Kids Science Experiments: Diffusion

I’m pretty proud of this one.

Elijah wanted to do an experiment.  He wanted to put food coloring in water.  I asked him what he would be testing with this, what was the objective, and he said we should put salt in it too.  I was pretty annoyed.  He just wanted to mix random stuff together!  That was no way to teach him the scientific method.  But when I thought about it, really, did it matter that much?  Did there need to be an objective every time?  Maybe the point should just be to encourage his creativity, which, after all, is a crucial skill for scientific thought later on down the road.

But I still felt that at least we needed something to compare, so I agreed to do two cups, both with salt, both with food coloring, but one with hot water and one with cold.  I figured it would be a lesson in diffusion, which one would mix all the colors better.  We put the salt in the cups, then the water, then the food coloring, and guess what happened?

Elijah has been super into what he calls science experiments lately. This makes me feel awfully proud, since that was always kind of my thing as a kid, but it has at times been a mess when I find his stashed concoctions and potions made of toothpaste, body wash, Halloween candy he can’t eat because of his food allergies, and God knows what else. I want to encourage it in a more directed manner, but I often find myself at a loss when he says he wants to make a potion or do an experiment. “Sure, you can help me make laundry soap!” Is not usually the kind of activity he’s hoping for.
