We cut up little pieces of tin foil and paper to be our fish. First we dropped in one and stirred the water. It was easy to spot. Then we dropped in a whole lot of fish, stirred it, and tried to follow just one with our eyes. It was much harder to follow one in the midst of many others. We talked about how there was safety in numbers.
This idea was adapted from Awesome Ocean Science by Cindy Littlefield. She suggests using glitter.
We went on to do a lot with this ocean unit. Be sure to check out this post at our new location, homeschoolden.com:
