Some Science

One of my goals is to do more science related things with Bear.  Nothing major, just more of a conscious effort to include a bit of nature study, biology, chemistry (well, we do do a LOT of baking), or physics each week.

This week we made oobleck
If you haven't made oobleck before, go into your kitchen now
and get your cornstarch and some water (the recipe I followed didn't work, so I just eyeballed it.  Maybe 1/2 cup water to 1 cup or more cornstarch) and mix.  You will get a substance that is a Newtonian Solid. 
It flows and pours like water, but when pressure is exerted upon it, it is hard and crumbly.
Bear didn't want to touch it at first, but ended up playing with it in the end. 
It oozes between your fingers just like slime. 




We talked about solid, liquid, pressure, slime, texture words like oozing, gooey, soft, hard. 
We did this in French and English.  It was a great vocabulary builder.
Then Dad walked in and was amazed because he doesn't read blogs and had NO idea what this was. 
J-jo watched from his perch in the middle of the kitchen island.  He spends a lot of time there observing. (Don't worry, he can't roll off as he's really too fascinated by his big sister to even think of moving and he is VERY far from any edges.)
