Science: Day 12

Fun with Non-Newtonian Fluids

Ahhh, who doesn't love a gak experiment. That's what Zhara picked out of the Pop Bottle Experiments to do today. So cornstarch quicksand it was today.

Funnily her father and I have always had an inside joke about loving non-Newtonian fluids. Why, yes, we are nerds, thanks. :) To the best of my knowledge she is not privy to said joke, but nonetheless...

It was fun. Zhara LOVED the goo. I encouraged her (strongly) to start a science journal and write down the experiment, how she did it, what she used, her measurements, and her findings. She is not a fan of writing, but she did it with only minimal whining, so I will vote success.

We talked about matter and it's four states, and how the cornstarch and water mixture does not follow the scientific rule for solid or liquid. Zhara had fun adding more and less water to various parts of the mass, and seeing what happened and where the tipping point was. Wednesday had fun making a mess. Fun times all around.

Look, she's writing findings!

The more we mixed, the harder it got!

We turned it upside down to see what happened.

Wednesday liked making a mess the best.
