I realized I really haven't been doing many crafts and such with Zack this summer. We've done some running around and some organized activities, but at home we've mostly been doing chores; so, this week we picked out some projects. At the top of our list was an experiment: what sinks and what floats?
We wrote a list of things we wanted to try the night before, along with a hypothesis about whether it would sink or float. Then we gathered up a bunch of items and gave them a try. It was a little messy and pretty fun. My ideas of stuff to try were things like a metal washer, a leaf, a piece of cork, cottonballs; Zack's ideas were more like "a chunk of peanut butter".
It was fun to talk about what makes us decide something will sink or float. Well, what was fun was my thinking I was doing some science instructing. No, no, I kept my inner science lecturer under wraps and we just played around. Well, played around and discussed the meaning of "density".
