Making Rocks and Fossils

This week we are continuing our study on Rocks.  We did two lab activities.  We made Model Rocks and made our own Fossils!

Model Rocks

To make a model rock we added a spoonful of sand, a spoonful of gravel, and a spoonful of glue into a cup and mixed.  Then the students put the glob on wax paper and when it dries, they will have their own homemade rock!

Making Fossils

To make a fossil the students flattened out a piece of clay.  I gave them a shell or a plastic dinosaur bone to press into the clay.  They pulled the piece out and filled the indention with white glue.  When it dried, we peeled the glue off and they had a fossil mold!

Since we have learned about different rocks and minerals and how they are formed, we played a game.  I have a True or False book about Rocks and Minerals.  We divided into groups and kept score.  The class loved it!  This is the book below and it went along very well with everything we have been studying!
