Chemist in our Classroom

 Today our class had a visit from a chemist.  Gabby's mom came into our classroom wearing a colorful lab coat and goggles. She came into reinforce the concept of absorption.  At first Mrs. DiVincentis spilled water on the rug and tried to clean it up with a block. We all knew that was a silly thing to do. Then she used a paper towel to clean up the water. She talked to them about how the paper towel absorbs and does not repel water.

 Then each child was given Instant Snow in a bowl and a beaker of water to pour into the bowl.  Each child was able to observe how when water absorbed into the snow it grew bigger.  To reinforce this concept further she also gave us little sponges to soak in water. They grew bigger as well. Then she had "jiggly jewels".  They are as small at first then they grew in water.

 We used our "alligator fingers" to try get the sponges to grow bigger.

Thank you so much for coming into our classroom and showing us how much fun science can be.
