Making Fossils

Yesterday, the students followed the directions that were in our story MonsterTracks for making fossils. The students did a terrific job sequencing the steps. We started with clean milk cartons. Water was added to sand until it could be shaped into a ball that held its shape. Each student put a ball of sand in the milk carton. They then pressed an item into the sand to make an impression. Equal parts of plaster of Paris and water were mixed in a bucket and poured over the impression. On Monday, we will release our fossils from the cartons. I can’t wait for the children to show you their finished products!
