Fossils

Today we had a great time hanging out with dinosaurs at the library. We learned a lot about how big they were, different ways we know about them, and how to make fossils.

One way we looked at fossils were some foot print fossils that I made for the kids. I took sand and pressed it firmly in the container. Then I pressed the feet of a toy dinosaur in. I added plaster of Paris and let it harden overnight. Then  I removed it, adjusted it so that I could cover it completely with sand in the container. The kids un-earthed their fossil foot prints and using tools were able to identify them.
