Will it Float?

I can't say enough good things about Donors Choose!  One of the things we got recently was the Can-Do Science Kit from Lakeshore.  One of the kits was the Sink or Float kit which included a plastic container, a plastic boat, eyedropper, a little plastic boat, marble, key, rubber ducky, wooden block, metal block, a small sponge, and a large sponge.   These little fingers.. they are just ITCHIN' to plop something in that water!!

Just taking it out of it's cylinder and the kids were all over it!  We all gathered around a table and I laid out the supplies and talked about what we were going to be doing and instructed on how to place, not plop, the item onto the water in the plastic container.

The kit has great little kid friendly graphic instructions.  The first "directions" card had us put in the rubber duck.

Now, the fun part.. to observe what was happening.  Just the simple question of "What do you see?" brought on many answers.  We finally got to the point where we noticed that he was on top AND not on top of the water.  He was displacing the water.  I LOVE the looks on their faces in this picture!!

Of course, the most fun was when they got to use it in a center by themselves.  He is concentrating so hard to try to sink the boat... just one drop of water at a time.
