Science Anecdotes for 9-year-olds

Help me brainstorm anecdotes from the history of science that kids will enjoy.

I've found that one interesting way of teaching science to my 4th-grade students is to tell them anecdotes from the lives of scientists. I don't mean the autobiographical curios; I mean episodes when they behaved as scientists and, perhaps, reached a profound insight. I invite the kids to think along with the scientist and share in the sense of discovery. The kids really enjoy these.

The only problem is, I only have a few of those (and some of them may be dubious historically). Some examples:

-- Galileo, daydreaming in church, observes one of the lanterns swinging as a pendulum. He decided to measure the timing of it movement against his heartbeats and discovers that its sweeps, long or short, always take the same amount of time.
-- Archimedes, bathtub, "eureka." (I explain it's probably fictional.)
-- Newton, apple, universal gravition. (Ditto.)
-- Hippasus thrown overboard for proving that the square root of two is irrational. (Lots of legends in science, eh?)

They don't have to be canonical moments with famous scientists; they can be obscure, as long as they're revealing and illustrate something about scientific thought. Any suggestions?

(p.s. Yes, I've read A Short History of Nearly Everything and am flagging pages.)

The discovery of radium by Madame Curie is pretty much the Gold Standard (so to speak) of this sort of thing, yes?

Seems like a rich source of these sorts of anecdotes would be television programs like James Burke's Connections or the similar parts of Carl Sagan's Cosmos.

from wikipedia on Pythagoras


According to legend, the way Pythagoras discovered that musical notes could be translated into mathematical equations was when one day he passed blacksmiths at work, and thought that the sounds emanating from their anvils being hit were beautiful and harmonious and decided that whatever scientific law caused this to happen must be mathematical and could be applied to music. He went to the blacksmiths to learn how this had happened by looking at their tools, he discovered that it was because the anvils were "simple ratios of each other, one was half the size of the first, another was 2/3 the size, and so on." (See Pythagorean tuning.)

Flatow's They All Laughed is chock-full of anecdotes and would be required reading for any kids I had.

Also, Burke's TV shows are also books. Circles, The Knowledge Web, etc.

In 1854, Dr. Snow gets a water pump handle removed and ends a cholera outbreak. His use of statistical information overlayed with maps moves epidemiology and public health forward.

A Short History of Everything also has tons of anecdotes of the type you describe from pretty much every branch of science.

They don't have the razzle-dazzle of running into the street naked shouting 'Eureka!,' but Mendel's pea-plant experiments in genetics appealed to me as a youngster.

And there's that thing about burrs and the invention of Velcro.

DERAIL/re Bozoburgerbonanza's link: In 1976, the microwave oven became a more commonly owned kitchen appliance than the dishwasher, reaching nearly 60%, or about 52 million U.S. households.

1976? That early? I remember microwave ovens still being a big deal--an exciting household purchase--in the late 1970's and even into the early 1980's. (..And it took an entire roll of holiday wrapping paper to wrap one of those monsters.)

A favorite of mine was always Kekulé's having realized that benzene had to have a ring-like structure during a dream/daydream/vision of a snake biting its own tail. Some historical dispute there, but he claimed it at any rate.

The story of Barry Marshall's discovery that Heliobacter Pylori is the cause of most stomach ulcers is a wonderful anecdote that illustrates the scientific method, the value of persistence in the face of conventional wisdom, and has a bonus gross-out factor that ought to appeal to 4th-graders (SPOILER: he drank a vial of bacteria to test his hypothesis on himself).

The New Yorker published a good little article on the story a few years back. Abstract here. I might I have a pdf of it somewhere if you're interested - mail me.

Well, before people used anesthetics for anything useful, ether and nitrous oxide were used as recreational drugs. The story goes that William Morton was at one of these ether parties one day when friend of his broke his leg but didn't seem to notice or care while he was all up on the ether. Morton decided to start using ether in his dental practice as an anesthetic, and now we don't have to be awake for surgeries anymore.

Ignaz Semmelweis worked in a teaching hospital with two maternity wards. The women and babies in the ward treated by midwives were thriving. The women and babies in the ward treated by medical students were all dying of puerperal fever. Semmelweis conducted a series of observational experiments and realized that his medical students had dissection lab every day before seeing the mothers (these were the days before anyone ever washed their hands). He made his students wash their hands in chlorinated water before and after seeing every patient. People died less. It was geat. (No one believed him, though.)

I always found the science-related deaths of scientists to be quite fascinating as a kid. Archimedes was slain during the siege of Syracuse when he asked one of the invading soldiers to move, since the shadow the soldier cast was obscuring Archimedes' diagrams. Sir Isaac Newton left a pot of mercury boiling next to his bed (for an experiment, one presumes), and died a lunatic from inhaling the fumes. Thales, an early astronomer/naturalist, was so absorbed in looking at the stars that he fell down a well.

More topically, we have, in the field of biology:

Francesco Redi, who refuted the theory of spontaneous generation by showing that no maggots would grow in meat which was enclosed in a glass jar.

Jean-Henri Fabre, the famous entomologist/naturalist, describes his experiments (on things like discovering the existence of pheromones, or the ability of a honey bee to locate nectar and communicate it to the hive) in a very picturesque and anecdotal manner, full of childlike wonder. Selections from his writings would make a great reading assignment.

Darwin sailing around the Galapagos Islands and finding multiple species of finches which were very similar, but had subtle adaptations of beak size and shape, adapted to the food sources available on the island they were on - these observations helped him to develop the theory of evolution.

Perhaps while discussing Isaac Newton and his light experiments, you could mention his invention of the "cat door" - his cat constantly wanted to go in and out of the room in which Sir Isaac was working (as cats are wont to do), but constantly opening and shutting the door not only took up too much of his time, it also let too much light into the room. He solved the problem by cutting a small hole in the door and covering it with a cloth which kept the light out but allowed Puss to come and go.

This could lead to a discussion about how even scientists have a soft spots for pets, and also how "necessity is the mother of invention."

Another thing I'd read from Darwin's voyage, although this is more oddball-anecdotal than scientific -- Darwin had noticed that unlike other kinds of lizards, the marine iguanas on the Galapagos could swim, and wanted to make sure that the one he'd seen swimming wasn't just a fluke. So he spent a good half-hour at one point throwing this one iguana into the water again and again, watching it swim to shore and then throwing it back.

I just always wondered what the iguana thought.

James Starley being thrown into a ditch by the unequal pedalling of his son on an early two-seater tricycle caused him to develop the differential gear.

I would certainly also mention Isaac Newton's cutting a smaller hole alongside after his cat had kittens. It's a funny anecdote, but there's a real insight there: Being confident you know the answer has little to do with knowing it, so always be ready to have a second look.

Descartes got the idea for his coordinate system (i.e. the Cartesian coordinate system) while lying in bed and looking at a fly on the ceiling. He realized that a coordinate grid would allow him to describe the exact location of the fly, wherever it might land.

Didn't the astronomer Tycho Brahe basically just build a gigantic compass and hold it up to the sky so he could measure the angles between stars better? At any rate it had something to do with just building a much bigger instrument and being very methodical. He also a pet moose, and one day he brought it over to a friend's house and it got drunk and fell down the stairs. He also lost his nose in a duel and replaced it with a gold nose. There are rumors that he died from bladder explosion because he was too polite to excuse himself from a dinner party, but I think they're unfounded.

The one where he made himself into a sort of paper-bus driver for household ants, in order to figure out how ants could find their way back home, is the sort of thing that kids can try at home. (Described in "Surely You're Joking Mr Feynman")

Wilder Penfield, applying current to the awake, neurosurgically exposed human brain, and provoking motor movement, or more dramatically, making patients relive childhood memories in great vividness. Mapping out the entirety of the cerebral cortex.

What a sense of wonder he, and his colleague the neurophysiologist Herbert Jasper, must have felt at that time.

When I was in high school, when my geometry teacher finished her lesson early, she would fill the few remaining minutes of class time by sharing little facts about math and science. Once day she told us how Mendeleev put together the periodic table, and how his ideas made so much sense to him that he left slots for elements that weren't known to exist, but would have specific properties if they did. And then, years later, elements with those very properties were found. I found that beautiful and amazing, and I've remembered it for almost 30 years.
