What Can 4-yr-olds Understand About Science?

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?"

4-year-olds don't understand

[Coryoth]

According to the studies I've seen 4-year-olds don't tend to have a very good grasp of abstract concepts, and in general understand a lot less than we tend to think -- we adults take a lot of knowledge and conceptual understanding for granted. That doesn't mean you can't make things educational, it just means you have to be careful with exactly what your goals are. I'm guessing that for 4-year-olds even getting them to realise that there is a problem (that we can be cued to think we're moving when we're not) would be a good start. You can probably do that by tricking them into thinking they are moving and then showing them that they weren't. That's relatively abstract -- that their perception of the world isn't always accurate -- but it is the sort of thing that they are starting to get a grasp of at that age anyway. They might not fully grasp it, but there is also the fact even if they don't get it at the time, such experiences have a habit of sticking around and helping inform later realisations, so make it memorable and it will be good. The sort of dawning realisation that could occur, that the world is stranger and more than it appears, and the idea that people (such as yourself) explore such things, well that's a good way to start a fascination with science and trying to understand the world.

be careful

I remember reading an article about demographic problems in germany. People have a very small amount of kids, and due to this problem they have unreasonably high expectations about their kids. It is frequent to hire a private teacher to work with the kid, to find many extra exercises for them like swimming, studying foreign languages (even at the age of 3!), etc.

The problem arising from that is a very high psychological stress the kid must cope with. High expectations from their parents cause headaches and other health problems, especially when a kid fails at some task. Give a kid free time.

In fact at that age all kid's time must be a free time. Your job is to find a method to put fun into a learning. Small kids decide what they want to do with their free time only directed by their enthusiasm at some activity. When you find yourself trying to convince him to do something you have already failed. You can only show your own enthusiasm, and show how fun it is. It's in fact easy to convince a kid when you are enthusiastic yourself (which is not frequent with teachers who are bored with their job). But when you see that the kid loses an interest you must immediatly stop.

And expect nothing! If you will expect that the kid will be successfull at anything you will only increase the stress level.

Hi kids! I'm a scientist, and I get to help figure out why people don't just fall over. Everybody stand up. Now, stand on one foot! Good -- Your muscles help keep you up, but why don't you fall? That's part of what I work on. OK, sit down, and I need a volunteer...

Ok volunteer -- have you ever caught a ball? Well, step back a little bit, and try this (tosses brightly colored sponge). You caught it! Toss it back, go a little further, and I'll try again. (Tosses sponge again) Great! Now -- just how did you know to do that? One time you were close, then you were far away! What happened to make it work? That is part of what I study too!

Who wants to pretend they're a tree? Stand up and hold out your arm! Wave arm with flappy winged bird doll. (Talk about flying birds coming in for a landing and not hitting the branch, or smacking into the tree.) Airplane pilots have to land their planes too, and not hit the ground too hard. I help figure out better ways to make that happen.

Visual stimulation and silly setups lead into simple explanations that kids can understand because they were entertained and their curiosity aroused. If they're giggling, they're able to learn becaue they're paying attention!
