Summary:"In this activity, students take a """"crayon rock"""" through different parts of the rock cycle. Students first create """"sediments"""" by shaving crayons to create a pile of bits and pieces (sediments)). Next, students apply pressure to the """"sediments"""" causing them to stick together. This """"sedimentary rock"""" is then heated until it gets soft, creating a """"metamorphic rock."""" The students apply more heat to melt the """"metamorphic rock"""" creating an """"igneous rock."""""
