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.
