Science Experimenting

16 Sep

Walter’s most frequent request since we started homeschooling is, “Can we do another science experiment?” I bought a kit online that shows you how to do 11 different things, usually involving changing colors with acids and bases and making things fizzle. Yesterday we did a really fun one that I had never experienced before. I’m pretty sure no science teacher has ever talked to me about non-Newtonian liquids — or if they did they never showed me this really simple experiment that would make it stick in my mind.

I suggest even adults should do this one night if you haven’t already. Or if you are talking to your child about solids and liquids, this is something fun to play with.

In a bowl:

Take 1/8 cup of water (add a couple drops of food coloring if you want. We didn’t have any and it was fine without it).
Mix in 5 tbs of cornstarch.

Now, as you play with it and squeeze it and drop it and softly touch it and knock on it and try to stir it with a spoon, ask yourself, is that a solid or a liquid?

Apparently even scientists don’t know yet why it does what it does!
