Use Sand Art to Teach Kids about Sedimentary Rocks

Every year I use Sand Art to teach kids about how Sedimentary Rocks form in layers. This is always one of my camper’s favorite activities. Sand Art gives kids a great visual representation of these different layers. Over the years, I’ve found a great way to do this activity without breaking the piggy bank. Pre-colored sand can be very expensive at craft and hobby stores. A great alternative is using salt that you color at home with liquid food coloring.

The Geology of Blue John Cavern

The Blue John Cavern is located in the Peak District in England near the town of Castleton, Derbyshire. The area of the cavern is formed within limestone strata that deposited in deep ocean waters millions of years ago. Layers of shale and some gritstone, a type of coarse sandstone common in this area, covered the limestone.
