What Can 4-yr-olds Understand About Science? 192
dr.karl.b asks: "My 3 and a half year old son is in Kindergarten. Here in Germany that includes 3 to 6 year olds. He is supposed to explain what his parents' occupations are. I am a scientist, and despite all the advice I have received saying he can't understand what I do, I am determined to try. I study self-motion perception, from basic-science vestibular processing to the role of real-motion cues in flight simulation. We have several cool labs in my institute, like robot-arm motion simulators and full-immersion virtual reality set-ups. We can easily compete with amusement parks for wow-factor, but I have 2 questions: How can I explain my work to my son? How can I invite his class (3-6 yr olds) to our institute to have them learn AND have fun, rather than ONLY have fun?"

But, she's just learning basic addition and subtraction now, so I'm not even bothering with conceptual models of chemistry, physics, etc. I also don't think she gets how far it is to her grandmother's house, much less what a light-year is.
These are a few guidelines I find useful:
Because of the building-blocks nature of science, I'm not sure how much you can teach to an entire group of kids who may be at square-1, but you can start with square 1. Maybe make them aware of their physical presence. Have them notice that they feel something when you flip them over. Play a movie for them with lots of motion while they're standing up and have them notice that they sway side-to-side.
Perhaps the greatest realization is that those first basic concepts are just as important as understanding the curvature of space in a warped fifth-dimension string theory, because you can't get anywhere without any of the underlying layers. And the sooner you start, while the brain is making connections like mad, the better off they're going to be later in life.
Oh, and make it fun. Science is a kick.

For a small child, they'll be able to understand that they know when they are moving, and in what direction, and they might even be able to tell you how they [think] they know that. If you have models of the canals in the inner ear, (I'm imagining tubes filled with coloured dye) you can provide an excellent demonstration that they should easily understand.
(BTW, I agree with Janek Kozicki's comment on high expections. While I was able to understand fairly advanced concepts at a young age, it wasn't because I was under pressure. My environment simply encouraged it; one family friend was a physics professor, another let me help out at the local natural history museum, etc.)

I knew from an early age that I would not be happy doing anything else but using my brain for a living. Despite a momentary lapse in sanity and earning a Bachelor's in Philosophy, I am now working full time as a network engineer while I spend my nights working toward a Computer Science degree. People don't know where I get the energy to spend my evenings after a long day at work doing mathematics and programming, but I say this-- if you had had the opportunity to look through a periscope that your own father had built, or help your father set up a helium-neon laser in front of the rest of the Cub Scout troop, or any of the other countless cool things I was able to do because of science-- you'd have no end of enthusiasm for the pursuit of knowledge either.
Just take your kids to work. Build rockets. Build anything with them, really. Anything but science or engineering simply will not be an option for their fervid minds.

I would bet that most 4yos understand the scientific method, even if they couldn't explain it. My daughter is 2 years 7 months and I can see the wheels turning in her mind. She has delaying her bed time down to a science. She has learned thru trial and error that being fussy at night results in her being put in bed. So she is extra cute and eager to play new games and show how smart she is. She has also learned thru trial and error that any loud noise from her room will bring one of her parents. The most important thing she has learned is that when Daddy puts her in bed, that's it, she's done for the night and any loud noises will not be rewarded by more time running about.
My wife, unfortunately, is insane, because, as we all know insanity is doing the same thing over and over and expecting different results. That's what I get for having a trophy wife.

The 6 year old then said "But our Dad's a scientist". The youngest then said "So you mix things together to make explosions then Dad?"
I said "Some Scientists do that, but I don't. But all scientists ask questions, measure or count things, and then write about it".
"Oh" he said. "so what do you do then?"
"It's like this - see how the road is a bit slippery?" - it had just rained that morning. "I start by having an idea that might explain why the road is slippery. Maybe there's lots of tiny little slimy fish on a wet road, and that makes it slippery". He had been amazed by how slippery fish are just the week before.
"That's silly Dad!" he retorted.
"Well, let's see if we can find a way to check if that's why the road is slippery. What do cats do when there's a fish lying on the ground?"
"They lick it" He said. suddenly looking very serious.
"Is our cat licking the fish on the road? What about the cats that live in both houses next to ours?"
He looked about. "No, I don't see any cats"
"So if we counted the number of cats licking little tiny fish so small we can't see them we'd get the number zero."
"Yes" he said.
"And we all agree that if there were tiny slimy fish lying on the road making it slippery there would be at least one of the 3 cats licking them?"
"Yes" he said.
"So is it likely there are tiny slimy fish on the road making it slippery?"
"No, there are no cats there".
"So we decide that the fish idea isn't right. A scientist will then get another idea about why the road is slippery, and he thinks up a way to measure or count something to see if it's a good idea. We keep on going until we get an idea that we can't prove is wrong. That's what all scientists do, no matter what sort of science they study"
He now has a fair understanding of the scientific method, and he knows that we have to measure (or count) things.
