Today in science we studied density, or why things float. The experiment was fairly obvious. Collect a bunch of stuff. Predict if it will sink or float. Then drop it in some water. Were you right? The boys LOVED it. In fact, an hour later, they are still at the kitchen table sinking and floating things. Aah, density.
Here are the pics:
Run, Luke, Run!
Sink or Float?
Our Sink or Float Chart. I started putting Y for "yes, it will float" but that became confusing so I switched to S for Sink and F for Float. The biggest surprise was the piece of wooden train track. The boys were positive it would sink. Explaining that wood is less dense than water made me feel like a genius and a magician all at once. They were VERY impressed.
Yes, I just added this one because it cracks me up.
