‘Bread Rocks’ Make a Fun Metamorphic Science Experiment

As sediments build up in layers over time, they may become compressed and turn into a sedimentary rock. A significant increase in pressure with low to moderate temperature increases may cause metamorphism to take place and turn the rock from sedimentary to metamorphic. This experiment will allow you to create your own sedimentary rock then with exposure to heat and pressure, change it into a metamorphic rock!

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.
