“Bread Rocks” Make a Fun Metamorphic Rock 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!
