RHMS Grade 7 students explored a hands on experiment with the rock cycle. Using Starburst candy, the students developed a model and observed the transformations that occur with the cycling of Earth's materials and the flow of energy that drives these processes. The rock cycle is a never-ending process. Igneous rock forms from cooling of magma or lava. Weathering breaks down rock into sediments that are compacted and cemented into sedimentary rock. Under great heat and pressure inside the Earth's crust, rocks are changed into metamorphic rock.
This was a fun STEM lesson that allowed students to see how different rocks are formed and what they look like.
