Sedimentary Rock

Sedimentary rock which was formed out of soil, silt, sand, seashells, bits of pieces of everything. The tiny bits settled and built up in thick layers. Minerals from water seeped into the spaces between the particles and bonded them into solid rock. The Grand Canyon is made up of sandstone, limestone, and shale which are all sedimentary rocks.

You will need:

Mixing bowl
Epsom salt
Small paper cup

Please have an adult's supervision for this activity.

Mix 1 cup of water and 1/2 cup of Epsom salt in a mixing bowl. Stir until most of the salt dissolves. Place about 1 inch of sand in a small paper cup. Add enough salt solution to just cover the sand. Mix well. Let the mixture stand until dry (about 2 to 3 days). Cut off the paper. 

Take a close look at the rock. Where is the salt? How does it hold the sand together?
