In this project, students will make their own fossils using plaster of Paris. They will learn about how fossils are formed and the history of life on Earth. It's a fun way to explore geology and paleontology!
If I create fossils using plaster of Paris, then I can replicate the fossilization process and understand how real fossils are formed.

Gather your materials and choose natural objects to create fossils.
Mix plaster of Paris with water in a bowl according to package instructions.
Pour the mixture into the plastic mold.
Press the natural objects into the wet plaster.
Cover the mold with plastic wrap and let it set for 24-48 hours.
Carefully remove the fossil from the mold.
Use sandpaper to smooth out any rough edges.
Label your fossil and display it.
You should have durable, realistic-looking fossils that replicate the fossilization process. This will help you understand how fossils are preserved over time.
