The Poisoner’s Handbook by Deborah Blum

 

So many crime novels of the Golden Age dealt with murders that involved poisons such as chloroform, arsenic and cyanide. It was the ‘weapon’ of choice in many cases back then because at that time (during the 1920’s and 1930’s) commercially made poisons were readily available and there were few tools available to detect those substances in a corpse. Solving a suspected murder was fraught with difficulties due to this inability to detect poison in the body and the lack of proper coronial procedures. Murderers often could not be convicted due to lack of substantial evidence.

The Poisoner’s Handbook: Murder and the Birth of Forensic Medicine in Jazz Age New York by Deborah Blum details the rise of forensic medicine in New York during the Jazz Age and concentrates on the work of two men: Charles Norris, a pathologist, and Alexander Gettler, a talented chemist. Both men were extremely driven and over a period of many years battled corrupt coroners, who often had no medical background, and a lax justice system. In the face of pathetic working conditions, lack of resources and meagre pay, Norris and Gettler pioneered forensic chemistry in the USA.

The author explores ten poisons, their use throughout history, and criminal cases in which they were used during the Jazz Age: 

Chloroform

Wood Alcohol

Cyanide

Arsenic

Mercury

Carbon Monoxide

Methyl Alcohol

Radium

Ethyl Alcohol

Thallium

'Carbon monoxide can be considered as a kind of chemical thug. It suffocates its victims simply by muscling oxygen out of the way…

The attraction between hemoglobin and carbon monoxide is some two hundred times stronger than that between hemoglobin and oxygen. No wonder that CO - as an invading gas - can cram into the blood cells, its tighter grip allowing it to displace the looser oxygen bonds…

In the alcohol-hazed 1920’s doctors tended to mistake CO poisoning for drunkenness, according to records kept by Norris’s office.'

The early twentieth century brought a flood of modern poisons into the USA. Morphine could be found in teething medicine, opium in sedatives, arsenic was included in pesticides and cosmetics, and many poisons were available to the general public in grocery stores.

January 20th, 1920 saw the official introduction of Prohibition in the USA. With legal drinking at an end, the availability of illicit alcohol grew and with it some deadly brews. In that same January, poisonous alcohol deaths increased and ‘speakeasies’ (unlawful places selling alcoholic drinks) became part of American life. This illicit alcohol could contain traces of other substances such as carbolic acid, Lysol or kerosene. The years after the introduction of Prohibition saw an increase in alcohol consumption and an associated recklessness. The Prohibition era was a great source of material for building an excellent science of alcohol intoxication if nothing else.

Forensic medicine in those years was quite gross. Gettler obtained organs from cadavers that were often months old and putrefying. He minced up these organs, boiled them, decanted, distilled, tested and retested them and came up with specific procedures for determining if poisonous substances were present. It was a growing technology that took years and a massive amount of effort to develop into a science that was finally recognised.

Norris and Gettler’s work not only helped to solve murders but also assisted in determining a person’s innocence. 

Indifference, greed and ignorance had allowed poisonous substances to become a part of everyday life in the USA. Doctors believed there were beneficial effects to smoking – it helped to control the appetite and therefore obesity and enabled people to cope with the stresses of living. Companies often mislabeled products and sometimes it took a major crisis for the government to take action. In 1938 Congress passed the Food, Drugs and Cosmetic act which gave the FDA the power to hold manufacturers legally responsible for harm caused by their products after a pharmaceutical company marketed a cough syrup that killed more than a hundred people, most of them children.

Thallium was put into depilatory creams and advertised in magazines like Vogue. Yes, thallium containing creams removed facial hair on women but it also made them bald. 

In 1928, Norris was approached by a colleague, a fellow graduate and crusader, Harrison Stanford Martland. Martland had some bones that belonged to a young dial painter who had died and he wanted to check them for radioactivity. Marie Curie’s ‘beautiful radium’ was the new miracle cure for all sorts of things, the ‘next best thing to drinking sunlight.’ It was anything but beautiful.

Martland discovered that radium has an affinity for bones. The dial painters, who practiced 'lip-pointing' their paint brushes covered in paint containing radium, became known as the ‘Radium Girls.’ They swallowed bits of the paint and absorbed radium into their bones. The radium blasted holes in their bones causing jaws to disintegrate and anaemias to develop in the bone marrow. As their bones decayed, they produced radon gas that the women exhaled while they were alive. Even five years after their death their bodies were found to be strongly radioactive. 

I enjoyed the medical and historical aspects of this book and Prohibition was an interesting thread running through it. The criminal cases were a bit too detailed for my tastes. Golden Age crime writers such as Agatha Christie, Dorothy Sayers and Ngaio Marsh tended to stay clear of the gory side of the crimes and concentrated on plot, character, motives and solving the crime. Most of the perpetrators in Blum’s book were just nasty and evil; others did not intend to kill but covered up their actions that caused harm – some companies, the U.S. Radium Corporation, for instance, who treated their staff abominably and used their legal team to wrangle themselves out of responsibility and deprive their staff of compensation.

It was the research publications of Martland and Gettler that enabled the women who were still alive to get a settlement in the case.

When Norris died at the age of sixty-seven, he left behind a carefully built team of forensic detectives who had a reputation for excellence.

Overall this was an interesting look at poisons and forensic detection. The author is a scientific journalist and the book reads like a journalist wrote it – a bit too much of a chatty sort of writing with too many diversions. She also concentrated on alcohol poisoning more than the other poisons.

A good read that was written in 2010 that would suit anyone interested in forensics, medical issues and the pharmaceutical industry.

The Island of Doctor Moreau by H.G. Wells (1896)



In January of 1888, a brig sailing between Samoa and California, discovered a man floating alone in a small open boat and rescued him. The man was Edward Prendick. Eleven months earlier he had been on a ship which collided with a derelict vessel and he was thought to have drowned. The tale he told his rescuers was so strange that they believed the solitude and danger he went through had made him mad.
His tale was thus:

After the collision he managed to climb onto a dinghy and some days later a schooner carrying a menagerie of savage beasts chanced to pick him up.
Montgomery, a man with a scientific background, was on board and he had been collecting animals to take back to an uncharted island in the Pacific where he worked with Dr Moreau, a scientist engaged in vivisection and bizarre experiments.
After an incident with the drunken captain, Prendick was evicted from the ship and stranded on the island when Montgomery disembarked. Moreau and Montgomery reluctantly allowed Prendick onto the island as his only other option was to drift in the ocean in an unseaworthy boat until he succumbed to the elements.
Bit by bit the secrets of this island began to reveal themselves. Moreau was breaking the laws of nature by experimenting with vivisection, blending one animal with another, and had created the strange ‘Beast People.’

‘Scarcely six weeks passed before I had lost every feeling but dislike and abhorrence for these infamous experiments of Moreau’s. My one idea was to get away from these horrible caricatures of my Maker’s image, back to the sweet and wholesome intercourse of men.’

Augustin Filon, a contemporary reviewer of the book, said that Moreau’s ‘...absurd and sublime dream is that of condensing the innumerable slow stages of evolution into a few weeks or months.’

However, one of Moreau’s victims escapes from his laboratory and attacks the scientist. The taste of blood causes the creature to relapse and incites the rest of the ‘Beast Creatures’ to similar behaviour. As they start to revert to their former animal states the island becomes a very dangerous place to be.

The Island of Doctor Moreau is a work of science fiction but it raises ethical questions that are relevant for today. In the pursuit of scientific knowledge and advancement, what ethical dilemmas should be considered beforehand? Even though we have the capabilities to push biological boundaries, how far should we allow ourselves to go?
This is an interesting book and H.G. Wells was a superb writer. I think it would be a good book for biology students to read & discuss but some sensitive souls may want to give it a miss.



Linking to Back to the Classics: An Abandoned Classic. I started reading this a few years ago but I wasn't in the mood for it then. As much as I enjoy this author's literary gift, his subjects are often a tad depressing!

Our High School Archaeological Studies



The Ring of Brodgar, Orkney


Gods, Graves & Scholars: The Story of Archaeology by C.W. Ceram

I’ve used this book in the past with my older ones and it’s very good. Ceram, a journalist and not an archeologist, traces the development of a highly specialised science in a way that the ordinary person can read it with genuine excitement as they would if they were reading a detective thriller.
The book was originally published in 1949 and was later revised and substantially enlarged. We have the 1971 edition and it is well-illustrated with black & white photographs, pen drawings and maps. There are 32 chapters, an appendix with chronological tables and a bibliography for the topics he covers.



The Folio Society have published the book and of course it's lovely, but expensive. Here is what they say about it:

'From Pompeii to the Rosetta Stone and from Nineveh to Chichén-Itzá, this hugely influential book was the first to tell the story of archaeology. First published in German in 1949, it was translated into 26 languages and became an international bestseller. More than any other book, it helped stoke a passion for archaeology in the imagination of the post-war world, and remains one of the world’s most widely read books on the subject...
Ceram tells us that ‘the great Palace of Minos was as large as Buckingham Palace’, that the bronze statues of Pompeii ‘rang like bells’ when they were first struck by the workmen’s shovels, and describes how our modern superstition about a black cat crossing our path stems from ancient Babylon.'

We're using Ceram's book as our main 'text' for the year and this term I'm adding in some fiction that is centred around archaeology. 

The Boy with the Brown Axe by Kathleen Fidler


This book is geared towards a younger audience (around 9 to 13) but I included it because it's a fictionalized account set in the Neolithic village of Skara Brae on the Orkney Islands which dates back 3,000 to 5,000 years ago. It describes how the village may have been destroyed and weaves in some geographical detail such as the Bay of Skaill, the Standing Stones of Stenness and Maidstowe. One of the characters in the book is a stone mason who is working on the Ring of Brodgar. Both my daughter and I enjoyed it even though it was a quick read for us.
Thanks to Sarah @delivering grace for suggesting this book.



The Rediscovered Village of Skara Brae





Crocodile on the Sandbank by Elizabeth Peters (1975)


This is the first book in the author’s Amelia Peabody series and it was a delightful read. We've both read this and my daughter loved it. While her characters in these books are fictitious, historic figures do make an appearance from time to time. For example, in Crocodile on the Sandbank, a well-known French Egyptologist plays a small part in the story. William Flinders Petrie, the famous archaeologist, is referred to a number of times, as well as a some other Egyptologists.
Amelia Peabody had lived a quiet life with her father, a scholar and antiquarian, generally supporting him and keeping house as he got older. The story takes place in the 1880’s. Amelia is 32 years old, single, and very sure of herself. 
When her father dies he leaves her his considerable fortune and she decides to leave England and travel to see all the places her father had studied: Greece, Rome, Babylon and Thebes.
She engages a companion, a Miss Pritchett, to go with her. Miss Pritchett contracts typhoid while they are in Rome and is dispatched back to England. Amelia, musing whether or not she should find a substitute, comes across Evelyn, a young English woman on the street near the Roman Forum. She had been heartlessly abandoned by her false lover when he realized she had no fortune and had fainted from hunger and exhaustion. Amelia rescues her, nurses her back to health then two of them take a boat up the Nile to an archaeological site to embark on their Egyptian adventure.

I looked into this series of books for my daughter to read alongside her Archaeology studies this year, for enjoyment mostly, but the settings bring archaeology to life and certainly give a feel for antiquity.
Elizabeth Peters earned her Ph.D in Egyptology and her archaeological knowledge comes through into her mystery writing which adds an authentic touch.
The author writes well and there’s a good dose of humour in her writing. Both my daughter and I think this first book has some similarities to Agatha Christie’s The Man in the Brown Suit, which we both really enjoyed.
I've started reading the second book in the series, The Curse of the Pharaohs, and while it's a great read, I think it may be just a tad mature at the moment for my daughter. Fortunately our library has a good number of the Amelia Peabody books so I'll check them out to see if they're suitable. I think once you've read the first one it's not necessary to read them in order. But do read Book 1 first if you decide to try them out!

Murder in Mesopotamia by Agatha Christie - a murder mystery set in a Middle Eastern
archaeological dig.





Appointment With Death by Agatha Christie - set in Petra. When Christie was 40 years of age she met her second husband, Max Mallowan, an archaeologist who was assisting Leonard Woolley in Ur. Christie worked alongside her husband and became an invaluable aid to him in his work. 

Ur from the air, 1927 - about a year before Christie visited

Ambleside Online Year 7 Highlights

Year 7 has finished up for the seventh time in our home, although this was only the second time we've used Ambleside Online for Year 7.  As I usually do, I asked my daughter which books were her favourites from this year's work, but I gave her a limit of ten. These are the books she chose:





I read aloud The Brendan Voyage, The Daughter of Time, and All Creatures Great and Small (which we are only half way through. It’s an omnibus edition and isn't scheduled in AO year 7.) She read the others on her own. The Magna Carta was a book we had that I added in - she really enjoyed this. The Daughter of Time and Fallacy Detective sparked a lot of interest, conversation, and ‘that’s a red herring’ type of comment on a regular basis!

As I mentioned, this is the second time we've done AO Year 7, and when I asked my next child up, Benj, who did Year 7 in 2014, what books were highlights for him. These are the books he chose:

Whatever Happened to Penny Candy
Ivanhoe
Watership Down
The Age of Chivalry
Eric Sloane's Weather Book
The Lord of the Rings Trilogy
The Talisman
Hereward the Wake
The Birth of Britain 


They almost have opposite tastes in reading. Ivanhoe, Watership Down, and Eric Sloane's Weather Book were not among Moozle's favourites and she still hasn't read The Talisman because she says she does not like Sir Walter Scott. Actually The Talisman was everyone else's favourite Scott novel.
Moozle loved the science selections but Eric Sloane's Weather Book went above her head at times - it was one of Benj's favourites. He didn't care for The Life of the Spider by Fabre (we have one of the world's deadliest spiders in our area so that probably didn't help) but Moozle got right into it and just about every reading was accompanied by a science journal entry.
However, they both loved The Lord of the Rings trilogy!

This verse from Ecclesiastes, that Charlotte Mason quotes in Volume 6, is very apt:

'In the morning sow your seed, and at evening withhold not your hand, for you do not know which will prosper, this or that, or whether both alike will be good.'



Ecclesiastes 11:6

One child may imbibe certain ideas from a book, while a different child won't, but we can't predict what ideas will inspire them. Our job is to provide a wide variety of books the same way we would provide food for a scrumptious smorgasbord. I've been quite surprised at some of the books that have been the trigger for ideas; books that I wouldn't have expected to charm them, but they have. Having children who've had almost opposite reactions to books has made this observation even more apparent to me:

Education is a life. That life is sustained on ideas. Ideas are of spiritual origin...we must sustain a child's inner life with ideas as we sustain his body with food. Probably he will reject nine-tenths of the ideas we offer, as he makes use of only a small proportion of his bodily food, rejecting the rest. He is an eclectic; he may choose this or that; our business is to supply him with due abundance and variety and his to take what he needs...out of a whole big book he may not get more than half a dozen of those ideas upon which his spirit thrives; and they come in unexpected places and unrecognised forms...

A Philosophy of Education, Pg. 109

I don't think a child has to love a book. They might find it difficult, and we may be tempted to drop it, but there needs to be some books that make them work a bit harder, build some more muscle, or they won't grow. It's not a cruel & unusual punishment to require them to persevere.

Many children are fussy eaters but we don't allow them to just eat junk because that's what they like & it will help avoid conflict for us if we just give them what they desire. If a child is sick or is convalescing, we make allowances by giving them the food they desire, within reason, but a well and healthy child doesn't get the same treatment.
A child may not be ready for some of the ideas presented in a book, but they will seize some of them while others may give them a foretaste that could develop at a later time. Smoked salmon, haloumi, and blue vein cheese might be passed over for other better known foods the first or second time around, but then one day they decide to try them and find they are very moreish. The other thing we need to consider is if overall the material is at a suitable level for them. If every book is difficult, perhaps we need to rethink our choice of books or grade level. 
Something I've made a point of doing this last year is to stretch Moozle's reading so that she's just not reading books with lots of action. She is a good reader but doesn't like slow books. A couple of those books I've mentioned towards the end of this post.

Other Highlights From This Year

In my original plans for Moozle's Year 7, I mentioned we were doing Apologia's Anatomy & Physiology. We finished that and then continued with The Way We Work by David Macaulay. Moozle loves Macaulay's illustrations in this book and I was surprised at how in depth the text is.






This section covered lipids and Macaulay used a number of technical terms that she wasn't familiar with. I found a video on lipids to help out. We'll be continuing with this book in Year 8.




A notebook page 


When my children get to about 15 or 16 years of age, I have them do a Senior First Aid course. In the past I've organised this and opened it up to some other families with older children & it's an intensive 2 day course. A few months ago, a homeschooling friend organised a course that ran over 4 weeks, one afternoon per week. Both Moozle and I did the course (a refresher for me) & I thought that spreading it out over a month was a good way to do it. There is so much information and doing it this way was much easier & left more time to let it all soak in.




Another focus this year was on Natural History Illustration which I wrote about here and here.

Handicrafts - the past few months have been devoted to patchwork and quilting. This is her major project.

Cello - this year she's preparing for the AMEB Grade 7 exam and has also had the opportunity to play in church a few times.

On the family front, the role of Aunty has come very naturally & she is a favourite with her little niece. We're all looking forward to the birth of our son and his wife's first child due in October and the wedding of our second daughter in September.


Some of Moozle's reading this year:

The Refugees by Sir Arthur Conan Doyle - 'Quite a good book but the main character behaved stupidly at times. Conan Doyle tends to make the Frenchmen excitable little wimps, while in books like this the Frenchmen always think the English are calm cool and collected, with no emotions whatsoever.' 4 out of 5

Lorna Doone by R.D. Blackmore - scheduled in AO Year 8 as a free read. 'It took ages to get into the book, rambled on at times, but it was a good story.' 4 out of 5
An illustrated kindle version is here.




The Spy by James Fenimore Cooper - set during the American Revolutionary War and written by an author who lived around that time period. This was Moozle's first book by Cooper and she didn't mind it, but I think she'll appreciate some of his other books a bit more later on. 3 out of 5

Midwinter by John Buchan - a little different to his Richard Hannay series. Midwinter is a tale of the  Jacobite rising set in 1745. John Buchan always gets a good rap in our house. 4½ out of 5:

'The Jacobite army marches on into England and Alastair Maclean, close confident of Charles Edward Stewart, embarks on a secret mission to raise support for the cause in the west. He soon begins to suspect someone close to the Prince is passing information to the Government, but just as he closes in on the traitor his own life is put in danger.'

The Black Stallion series by Walter Farley - this is a series that Moozle has enjoyed for a few years now and she added a couple more to her collection recently. 4½ out of 5.  

I've been thinking about the next year's work and my plan is to cover AO Years 8 & 9 over eighteen months. I have a couple of reasons for this. One is that the school year here in Australia goes from February to December with a fairly long break over Christmas. We've never followed the school terms but I'm finding more and more that our outside activities do. Just about everything shuts down for the school holidays and the Christmas break and we often end up catching up with people during the official school holidays. There's also much less traffic at those times so it's easier to get out and about.
The other reason is so that Moozle isn't straddling two years - she started Year 7 in the middle of last year. At the end of next year she will have completed Year 9 and then she'll start Year 10 at the beginning of the next year...if that makes sense!  Anyhow, that's the plan & I'm looking at the AO schedule here - starting at Week 25, which will take us through to the end of the year and then continuing with this next year. So instead of doing AO Years 7, 8, & 9 in two years, we'll be doing Years 8 & 9 in one and a half years. Clear as mud?

Edited to add our weekly schedule. This is what I've done for many years - give the schedule out at the beginning of the week and let them decide which books to do each day. I check each day to see what's been done and if I find they've gotten a bit lax, I'll give them a list of things I'd like completed. Each of my children has had a preference for certain subjects so I make sure they haven't left things out and if they have, get them to attend to it the first thing the next day. 
They have all tended to like doing a book chapter in one hit & not spreading it out over a week - even the longer reads such as Churchill's Histories.







My original plan for Moozle's Year 7 - I made some modifications especially with Devotional reading and Science. 

Highlights from Term 1

Australian content

Apart from what I mentioned in my original plans, Moozle read & re-read some Australian titles this year. Many of the books I want to use I've either used in earlier years or plan to use later on when she's a little older. I picked up a couple of Nan Chauncy books we didn't haveTiger in the Bush & Tangara and she read those but they were easy for her. 
The Silver Brumby series are some she re-read and enjoyed doing so. They are excellent reading.

I have a page at the top of this blog where I record some of the Australian titles we've read.

My Homeschool
has some options for Australian families that includes assistance for those needing to register with the government.

In Defence of Old Science Books


A common charge against Charlotte Mason educators is that we use too many old books. When it comes to teaching science, this objection is even more vehement. How can you teach science using books that were written ten, twenty, thirty or worse still, over a hundred years ago?
Yes, we do tend to use older books but that's not because older books are intrinsically better than more modern titles. There are plenty of dud older books that we'd never use for the good reason that they aren't well-written. The reason we'd choose an older book over a more recent is because it has a literary approach, i.e. it presents facts that are clothed in literary language.
More and more, education has become utilitarian in its approach, and this is reflected in the teaching of science and the content of the books that are used. David Hicks made this observation:

'...as science took a technological turn and as education began preparing students for work rather than for leisure, for the factory rather than for the parlor, the school itself came to resemble the factory, losing its idiosyncratic, intimate, and moral character...
In its utilitarian haste, the state often peddles preparation for the practical life to our young as the glittering door to the life of pleasure; but by encouraging this selfish approach to learning, the state sows a bitter fruit against that day when the community depends on its younger members to perform charitable acts and to consider arguments above selfish interests.'




Norms & Nobility by David Hicks

When a book is too direct and factual there's the possibility that the student may not appropriate the material.
I've thought about this not only in relation to my children but also to my own reading. Some thoughts on uniting the literary & the scientific here.

Of course some things will have changed from when a science book was first written, but we could say that about a science text that was written a year ago. There are ways to bring the knowledge up to date without too much trouble while still giving your student the foundational concepts padded out in a literary medium. YouTube videos are one way that's worked well for us. The chapter from the book is read first and then an appropriate video is shown after that.
We take care that:


'...all knowledge offered him is vital, that is, that facts are not presented without their informing ideas.' 
Towards a Philosophy of Education, pg xxx


Some of the science books I've been using this year for my 13 year old daughter are in the 'old' category. Some are more modern, but they are all good. The first three book below are scheduled for Year 7 (Form III) at AmblesideOnline.


The Life of the Spider by Jean Henri Fabre (1823-1910)

Notebook page for The Life of the Spider 


The Wonder Book of Chemistry by Jean Henri Fabre - translated into English in 1922

These two books by Fabre are my daughter's favourites. Interestingly, Fabre was not only a scientist but a poet (see a short bio here). Charlotte Mason said of French scientists that,

'...they perceive that as there is an essence of history which is poetry so there is an essence of science to be expressed in exquisite prose.'


 Notebook page after reading Chapter 17 of The Wonder Book of Chemistry
 

I've used some of the University of Nottingham's Periodic Table of the Elements to not only bring some of the concepts in The Wonder Book of Chemistry (and other books we've used in the past couple of years) up to date but also to see demonstrations of science experiments that we wouldn't be able to perform safely at home.

Eric Sloane's Weather Book (1952)

The BBC's Wild Weather series narrated by Richard Hammond have been helpful with Sloane's book which on the surface looks simple enough but contains some difficult topics where a visual or simulated demonstration is helpful.

Architecture Shown to the Children by Gladys Wynne (1913)




This year we started Architectural Science and Gladys Wynne's book is our primary text. I've added in a couple of other books we have that relate to the science behind architecture such as String, Straightedge, & Shadow: The Story of Geometry by Julia E. Diggins (1965)
Although this would be classified as Mathematics and not Science, we're using it alongside the above book as it relates to Architecture in the Ancient World. The Grand Design DVD's are also an enjoyable addition from time to time.



Some examples from Moozle's Architecture Notebook






Secrets of the Universe by Paul Fleisher - this was originally published in 1987 and is out of print but it was re-issued as five separate books in 2002. Moozle is reading this one at present:




This is a series that a few of my children have enjoyed and learnt quite a lot from. Fleisher has explained the concepts well and included experiments that are do-able in the home situation. This was one Moozle did on light reflection last week:





Signs & Seasons by Jay Ryan (2007) is a more recent science publication but I'm supplementing with The Constellations & How to Find Them by Sir William Peck (1942) as he writes from a Southern Hemisphere perspective.





I managed to find a sundial in a local park


Natural Science

The older books really shine with this subject and just about every book I have related to this field is old. I have up to date field guides for studying birds and plants in our part of the world but reading the writing of earlier naturalists is very inspiring. An interesting article I found about this: What Early 20th Century Nature Study Can Teach Us.
Some of the books I use the most are:

Natural History in Australia by William Gillies & Robert Hall (1903)

Handbook of Nature Study by Anna Botsford Comstock (1911)

Bush Calendar by Amy Mack (1909)

I posted a list of some of these that are available free online here. 




Mother Culture Science


These are some science titles I've read for my own education, or have used with my older children in the high school years. I've linked to reviews I've written on them or where we've used them in high school.

Uncle Tungsten: Memories of a Chemical Boyhood by Oliver Sacks (2001) - my own reading and one of my sons read it around the age of 16 years.

Longitude by Dava Sobel (2011) - this was a book I read aloud about 5 years ago to multiple ages

Madame Curie by Eva Curie (1937)

The Immortal Life of Henrietta Lacks by Rebecca Skloot (2010)

The Double Helix: A Personal Account of the Discovery of the Structure of DNA by James D. Watson (1968)

Understanding Physics by Isaac Asimov (1966) - we used this in Years 9-11

Mr. Tompkins Inside Himself by George Gamow & Martynas Ycas (1967)

The following books are medically related, inspirational/devotional & highly recommended:

Fearfully & Wonderfully Made by Philip Yancey & Dr. Paul Band (1980)

Ten Fingers for God by Dorothy Clarke Wilson (1965) - a biography of Dr. Paul Brand

Free stuff for the Study of the Human Body - Updated

Some free stuff we're using for studying the human body:

August 2017: some of the links I originally put here don't work anymore so here are the updated ones:

The website http://www.ue.net/body-eng/ contained the text from 'Your Body & How it Works' by Dr. J. D. Ratcliff, the author of  I Am Joe's Body but I haven't been able to link to it lately.

I did find that I Am Joe's Body is now available at Archives.org, which wasn't available when I last covered Anatomy & Physiology.


Khan Academy also have a series of videos on Human Anatomy & Physiology - I haven't viewed these yet but they look like they are for upper level highschool.


The next three videos cover Genetics. They are done quite well but if viewing with a younger child check the third one as it explains fertilisation. It's tastefully done and shouldn't be a problem:
















The next two are videos on the Integumentary System. The first one explains the layers of the skin and the second how first, second and third degree burns affect the skin.












This one is a journey through the human eye which I thought was one of the simplest and best explanations I've come across. It only covers the main parts of the eye but enough to make its function clear.

The Immortal Life of Henrietta Lacks by Rebecca Skloot




For many years scientists had been trying to grow human cells outside of the human body in order to have a continuous (immortal) line of cells that would constantly replenish and that could be used to study any number of things,  especially viruses. Mouse cells had been cultured successfully, but every attempt to culture human cells had failed.
That was, up until 1951. That year, Henrietta Lacks, a 30 year old black mother of five young children, was admitted to the coloured ward of John Hopkins Hospital to have a biopsy of her cervix. A sample of tissue from her cervix was sent to George Gey, the head of tissue culture research at Hopkins.
At that time, if doctors wanted to use tissue from patients for purely research purposes, patient consent was not required, although it is now.
Henrietta Lack's tumour cells were put into culture and they didn't merely survive, but grew like nothing else had before.
The tumour turned out to be a very aggressive form of cervical cancer, and before long, millions of the cells had reproduced themselves in the laboratory. Gey and his assistants had grown the first immortal human cells which they named 'HeLa,' for Henrietta and Lacks. These cells became one of the most important tools in medicine and have been used in the development of the polio vaccine, in gene mapping, cloning, cancer research, and researching the effects of zero gravity and radiation on the human body.

The Immortal Life of Henrietta Lacks is a real page turner of a book and quite fascinating generally.
Rebecca Skloot is a journalist, which partly explains the readability of her book, and also the style in which she writes the story. To me this was both positive and negative. Positive, in that the scientific concepts were explained well enough for a lay person to understand and in a narrative style; negative, where the author injected certain incidents, such as the abuse of Henrietta's children by family members after she died, and other intimate family details, throughout the book.
I wondered whether this was really necessary, but an important aspect of this book is the recognition that behind all the science and research, there are real people. The author certainly portrayed this well.

I'm not American, so I didn't come to this book with any personal background experience of USA race relationships or much knowledge of the history and implications of segregation, therefore my reactions to this book are as an outsider looking in.
I had the impression at times that the culture of Henrietta Lacks' cells and the subsequent profits derived from their use (that the family never benefited from) was blamed for everything that went wrong with the Lacks family afterwards, but there was some serious dysfunction in the family before Henrietta ever went to hospital.
It was tragic that five young children lost their mother, but she had fairly advanced cervical cancer by the time she presented to John Hopkins' Hospital, and the treatment of cervical cancer wasn't clear cut at the time. She had the standard treatment of the time: radium and X-ray therapy. (See my comments on Cancer Ward, set in the 1950's.)
The author reveals scientific research that went beyond the bounds of decency, although not in Henrietta's case: research using cancer cells perpetrated upon unsuspecting black patients (see the infamous Tuskegee Study) that were likened to the Nazi experiments of WWII. Prison inmates were used as human guinea pigs, and the conditions of the 'Negro' mental institution where Henrietta's eldest girl was sent before her mother died were disgusting. Were other mental institutions at the time any better? I don't know.

There were also privacy concerns raised by the family. Henrietta's medical records were released without their consent, and blood was taken from various family members for research purposes without full disclosure. In fact, the family had no idea what was happening.

Henrietta's family were uneducated and ignorant of science so when they found out that her cells were 'alive' it was very confusing for them and this misunderstanding caused them a lot of unnecessary anguish. They thought that parts of her were still alive and that she could feel pain when experiments were performed on her cells.
The family also wondered, if Henrietta had been so important to medicine and scientists were buying her cells, why couldn't the family afford health insurance?
This is one of those areas where science leapt ahead before the ethics had been worked out. And this still happens.
The author included a very informative afterword that addresses tissue research and patient rights at the time the book was first printed in 2009, and gives examples of other individuals who took action against medical practitioners who profited by the sale of their patients tissues.
Fascinating!
Cell research is vital. It needs to be done ethically and in an informed manner, but what a huge can of worms we've opened up!

Some other thoughts:

Henrietta Lacks was an uneducated woman from an impoverished background and like most black patients at the time, she only went to hospital when she thought had no other choice. As I mentioned above, there had been some very unethical research conducted at the Tuskegee Institute, and other incidents, that generated suspicion of the medical profession amongst black communities.

Many doctors back then used public patients for research, generally without their knowledge - these patients were being treated for free so it was considered fair enough to use them as research subjects.

In the 1950's "benevolent deception" was commonly practiced and so it was not uncommon for patients to have no idea of their diagnosis, especially if it was something as distressing as cancer. This was also the practice in the USSR in the book I mentioned above.

Henrietta was not told that her cells were replicating themselves in a laboratory and her family only found out inadvertently about twenty years later. By this time HeLa cells were a huge business and were sold and sent all over the world.

When the family realised that people were making money out of their mother's cells, they became angry, especially when they couldn't even afford medical insurance.

At the time this book went to press, blood samples and body bits taken during procedures such as removal of moles, ovaries, appendices, and tonsils - which are given voluntarily - are often kept indefinitely and later used to develop things like vaccines and drugs and no permission is required.

Rebecca Skloot first heard about HeLa cells when she was sixteen and doing a community college biology class. She spent a decade researching Henrietta's background including time spent getting to know Deborah Lacks, Henrietta's daughter, who helped provide much of the information for the book.

The documentary below, The Way of all Flesh was filmed in 1998 and is a very interesting account of the science behind the HeLa cells:





I read somewhere that a version for younger readers was published in 2012: The Immortal Life of Henrietta Lacks: The Young Reader's Edition by Gregory Mone, Rebecca Skloot, 256 Pages, Published in 2012, but it looks like it's out of print.

Potpourri: Reading, Commonplacing & Leisure


 The view at the end of an impromtu bush walk


Over the Easter period I've been soaking up all the loveliness I've found in this complilation of literature: 'Between Midnight and Dawn.' I love poetry and there are some poignant pieces in this book, old and new, and although I'm not usually drawn to contemporary poems but there were some that hit me hard. And this one - Oh my! This made me catch my breath! 'Preparing for Joy: Waiting to be Filled'

I've come to the end of The Count of Monte Christo by Alexandre Dumas, which I'll write about in more detail later. What an epic this is! All the way through I kept thinking of the biblical admonition, 'Vengeance is Mine!' says the Lord.

"Oh!" he exclaimed, as though a redhot iron were piercing his heart. During the last hour his own crime had alone been presented to his mind; now another object, not less terrible, suddenly presented itself. His wife! He had just acted the inexorable judge with her, he had condemned her to death, and she, crushed by remorse, struck with terror, covered with the shame inspired by the eloquence of his irreproachable virtue, -- she, a poor, weak woman, without help or the power of defending herself against his absolute and supreme will...
"Ah," he exclaimed, "that woman became criminal only from associating with me! I carried the infection of crime with me, and she has caught it as she would the typhus fever, the cholera, the plague! 

Wildflowers in bloom


I'm about half way through The Weight of Glory by C.S. Lewis, which is a compilation of essays on diverse topics. The quotations below are from the essay, 'Why I am not a Pacifist.'

How do we decide what is good or evil? The usual answer is that we decide by conscience...an autonomous faculty like a sense cannot be argued with; you cannot argue a man into seeing green if he sees blue. But the conscience can be altered by argument...Conscience, then, means the whole man engaged in a particular subject matter.

Good philosophy must exist, if for no other reason, because bad philosophy needs to be answered.





The Disappearing Spoon by Sam Kean

I was looking forward to reading this book as part of my ongoing science education but I've been a little disappointed so far. I'd describe the author's writing as 'breezy' which annoys me, as well as his gossipy style and the inclusion of slang in places. Oliver Sacks and even James Watson were more literary in their style of writing, whilst still being humorous and entertaining. Kean's attempts at both feels forced  - but I should reserve my judgement until I've read more of the book, I suppose.
He does have some helpful suggestions such as looking at a blank periodic table without all the clutter before introducing it to students, and his comparison of the structure or 'geography' of the periodic table to a castle made of bricks - each brick being an element, which if taken out of its position would result in the castle tumbling down, was a helpful one.




Norms & Nobility by David Hicks

Continuing my SLOW read of this book. This book is expensive but you could spend years chewing on the ideas expressed by the author. I gave up trying to keep up with the AmblesideOnline Forum discussion on this book which started at the beginning of this year, but am progressing at a snail's pace on my own regardless. One idea that seems to be popping up in various places for me is that of utilitarianism. One of our boys is in the first year of a Liberal Arts degree and he is constantly asked, "What does that qualify you for?"
 Life??

Dr. Johnson recognized the temptation to make education a preparation for the practical life either by concentrating exclusively on science or by turning all studies into sciences. Predictably, as science took a technological turn and as education began preparing students for work rather than for leisure, for the factory rather than for the parlor, the school itself came to resemble the factory, losing its idiosyncratic, intimate, and moral character...
In its utilitarian haste, the state often peddles preparation for the practical life to our young as the glittering door to the life of pleasure; but by encouraging this selfish approach to learning, the state sows a bitter fruit against that day when the community depends on its younger members to perform charitable acts and to consider arguments above selfish interests.

The Double Helix: A Personal Account of the Discovery of the Structure of DNA by James D. Watson


In 1953, Francis Crick and James Watson (who was only 24 years of age at the time) presented a scientific paper that proposed the double helical structure of DNA. Up until about 1944, DNA had been ignored and was considered to be 'the stupid molecule.' It was so simple, that it couldn't possibly play any major part in the body.
With the discovery of the double helix formation, the replication of genes and their role in the transmission of information from parents to their offspring became obvious. This discovery was a major turning point in science and the beginning of modern genetics.




The Double Helix, first published in 1968, is an honest, humorous, chatty, and at times sarcastic, first-hand account by James Watson of his version of how DNA was discovered. An American, he moved to Cambridge University in 1951 after studying in the USA and Copenhagen. It was at Cambridge that he met Francis Crick, who, like himself, was interested in how genes were constructed and the role of DNA, and together they made the discovery that revolutionised biochemistry.
James Watson has written a unique book in many respects. This is the inside story - a glimpse into the rivalries, the insecurities and the ambitions of scientists; their struggles, triumphs and disappointments. Watson didn't hold back on his opinions and at times he was crude and unkind to his fellow scientists, but his honesty in portraying the attitudes and eccentricities of the scientific community was a refreshing approach.
I was impressed with the positive reactions from the various scientists when Crick and Watson's discovery became known. Previous rivals and runners in the race were genuinely thrilled with the news and recognised its huge impact for the development of science.
This is a good read for anyone interested in science and genetics. It does get a little technical in places but not enough that you'd miss the gist of the story, although a good grasp of chemistry would definitely help. Watson gets sidetracked at times with comments on pretty girls, parties and random misogynist observations so I'd recommend a pre-read if you're thinking of using it in high school.

'I have never seen Francis Crick in a modest mood...'

'...there existed an unspoken yet real fear of Crick, especially among his contemporaries who had yet to establish their reputations. The quick manner in which he seized their facts and tried to reduce them to coherent patterns frequently made his friends' stomachs sink with the apprehension that, all too often in the near future, he would succeed, and expose to the world the fuzziness of minds hidden from direct view by the considerate, well-spoken manners of the Cambridge colleges.'

'One could not be a successful scientist without realizing that, in contrast to the popular conception supported by newspapers and mothers of scientists, a goodly number of scientists are not only narrow-minded and dull, but also just stupid.'

'Meeting the Requirements of Mind' - Year 11 Science


I have so far urged that knowledge is necessary to men, and that, in the initial stages, it must be conveyed through a literary medium, whether it be knowledge of physics or of Letters, 
because there would seem to be some inherent quality in mind which prepares it to respond to this form of appeal and no other. 

Philosophy of Education, pg 334

From what I've observed, the teaching of science is generally not conveyed through the literary medium that Charlotte Mason thought was so necessary. At first I had to grapple with the idea myself, but later on I saw that this approach worked when a factual presentation failed to accomplish its purpose.
However, I have observed that some of my children, after a period of time, are quite comfortable with a textbook format for some areas of science, and actually enjoy using it - shock & horror!
What about living books?
Charlotte Mason had some interesting things to say about the use of books and it was a very profitable exercise to study what she'd observed in her experience of many years when I was writing a post for Brandy's CM Myths series a couple of years ago. It helped me understand that textbooks are not anathema and may have a place in a CM education.

Benj is doing Year 11 science this year. Ambleside Online have some wonderful 'living book' science options up to year 8 at present, but they are still working on the later years. They have a few options at present for Year 11 and one of them is Apologia Science.

Three of Benj's older siblings used Apologia Chemistry at this stage. His two sisters had no problems using this and it sparked a real interest in the subject for the eldest. She studied chemistry at university level and said that Apologia Chemistry gave her a solid preparation for this. My eldest son had a different experience but we didn't have anything else to substitute at that time so he just endured it.

To continue with what Charlotte was saying in the quote above:

I say in the initial stages, because possibly, when the mind becomes conversant with knowledge of a given type, it unconsciously translates the driest formulae into living speech...        

This observation was an eye opener for me as I didn't understand why my girls did so well with the chemistry text and my son (who had no problems academically and had a 'sciencey' way of thinking) struggled. I knew it wasn't an intelligence issue but from what Charlotte Mason observed, the girls must have been able to translate the material into living speech.                         

I'm not saying that Apologia Chemistry is dry and formulaic. I don't believe it is, but it does require a student to 'translate.' They need to have a solid working knowledge of Algebra to make sense of this course. Although my son had completed Algebra 1, he didn't have the fluency required:

...perhaps it is for some such reason that mathematics seem to fall outside this rule of literary presentation...

I've read this quote numerous times but only in a maths context, with no connection to anything else. Our minds need to be familiar enough with the maths involved in the science so that it may be translated. Charlotte Mason observed that mathematics has a language of its own:


...mathematics, like music, is a speech in itself, a speech irrefragibly logical, of exquisite clarity, meeting the requirements of mind.

I had further confirmation of Charlotte Mason's observations with my fourth child who needed a literary presentation of science all the way through high school. He was required to study Physics as part of the Cadetship he entered after graduating, and I wasn't sure how he would handle the 'driest formulae.' He turned 18 the year he started his Cadetship and within a short time he had made the transition from the 'initial stages' to the 'translation' phase.

So back to the present:


Contrary to my earlier expectations, Benj appears to have made this transition from the initial stages into the translation phase in the past year and a half and as we were approaching Year 11, we talked about options for science. He had a look at Apologia Chemistry and said he'd like to try it. This is the plan we decided upon:

The Microbe Hunters by Paul de Kruif (1926) - this book is used in previous AO years and Benj will just continue on with the chapters scheduled for this year.
The author presents the lives of the 'microbe hunters' in a sympathetic and affectionate manner; not as supermen but with all their foibles and humanity meshed with their brilliant minds. It's a very engaging book.




Koch was as coldly logical as a textbook of geometry...Koch always recited his failures with just as much and no more enthusiasm than he did his triumphs. There was something inhumanly just and right about him and he looked at his own discoveries as if they had been those of another man of whom he was a little overcritical. But Pasteur! This man was a passionate grouper whose head was incessantly inventing right theories and wrong guesses - shooting them out like a display of village fireworks going off bewilderingly by accident.

*   Understanding Physics by Isaac Asimov - this contains  three volumes in one that Benj started about a year ago. This book has been around since 1966 and there are some good reviews on Goodreads and Amazon. This website explains the content of each volume. Benj is reading through the third volume: The Electron, Proton and Neutron and really enjoys Asimov's writing.
He remembers quite a bit of this from his earlier reading of The Mystery of the Periodic Table and the early chapters of Apologia Chemistry overlap a little also.






*   Apologia Chemistry - as I mentioned above, this text requires a good working knowledge of Algebra and my children who have done well with it have completed Algebra 2 (in our case this was Saxon Maths). I'm using the 2nd edition that I used with his older siblings and haven't seen the newer editions. We've always managed to get most of the experiments done with basic household products. Benj will use a few different ways to narrate what he has learned - record the experiments in a lab format, do a notebook entry or write a series of questions which he needs to be able to answer.







*  Natural History - keep up his nature notebook, outdoor observations, special studies. This term we're concentrating on birds and are using The Handbook of Nature Study by Anna Comstock and Nature Studies in Australia by William Gillies & Robert Hall.

*  Science biographies - a couple of possible options which I've read and written about include:

Madame Curie by Eve Curie
Uncle Tungsten: Memories of a Chemical Boyhood by Oliver Sacks


How to discern whether or not to use a textbook for science:


There are textbooks, and there are textbooks. If a student can't narrate what they've read in a book it's usually a good sign that the book isn't suitable. There are other ways to determine if a book is suitable and I referenced some quotes from the Charlotte Mason series in the article I linked to above that address this.
Apologia Chemistry differs from standard textbooks in that it has been written by one person, not a committee. Jay Wile, the author, obviously enjoys his subject plus he has a positive attitude to home education and has written specifically to that audience.

Update: I just found this by Jay Wile - he's written a new Chemistry book & discusses the differences between the edition we're using and the new one.

This blog has some information on teaching science using Apologia in the higher grades, the maths required for certain texts, plus a format for lab reports.
