Making Fossils





On Friday of last week, we took objects (like shells, twigs and rocks) and pressed them into clay. We filled the imprint with glue and let it dry over the weekend. When we came back today, they had all hardened. With this experiment, the kids demonstrated the difference between molds and casts. The imprint left in the clay was the MOLD. The dried glue demonstrated the CAST. They LOVED making their own fossils.

 FUNNY GUYS!
