Jaclyn Lockett’s sixth-grade science classes are learning about metamorphic, igneous and sedimentary rocks within the rock cycle. Students used Starburst candy to recreate them! (How cool is that?)
“I had a lot of fun. I learned that when I made a sedimentary rock I could turn it into metamorphic by putting extreme heat and pressure on to my rock,” said Trace Dejong.
Metamorphic rocks are any rock type that has been altered by heat, pressure, and/or the chemical action of fluids and gases. Igneous rocks are those that solidify from a molten or partially molten state. Erosion and deposition play a key part in the formation of sedimentary rocks. Wind, water, ice, and chemicals break down existing rock into sediment that is then transported and deposited by wind, water, and glaciers.
