Sink or Float?

Our homeschool theme this week is "By Sea and By Sky." Basically, we're reading and learning about boats and planes. We did a little bit of science this afternoon. I had collected several items and we tested them in a big tub of water to see if they would sink or float. I figured this would be a very easy, but fun activity for the boys. It was, indeed, very easy for Ray. I was pleasantly surprised by the accurate explanations he had for why things sank or floated. He became quite the little teacher, helping Adam make predictions and explaining why each item sank or floated. The challenging part for him was learning how to correctly mark the chart we made.

Then, after the official lesson, they played for quite a while in the water. They tested lots of other items, turned the water green with food coloring, added shaving cream, scrubbed things. It was fun and not too messy.
