Science fair project that examines the behavior of water and gravel in creek beds and the formation of sedimentary rocks.

In this science fair project, students use the streak test to tell minerals apart from each other.

In this science fair project, students learn how pressure can make the minerals in a rock line up in the same direction and form bands and foliation.

In this science fair project, students discover how sedimentary layers form as sediments like mud, silt and sand settle over time.

The next time you've got a restless second grade earth scientist on your hands, use this experiment to demonstrate crystals and make a tasty treat, too!

Learn about the layers of the Earth and make a model! Create a earth layer book, cake, or clay diagram.
