Investigate the rock cycle. What is a rock? What is the rock cycle? How do rocks form? How are they classified? Your students will answer these essential questions as they conduct a series of hands-on activities. Using the set of rock specimens included, they will observe the distinct characteristics of each type of rock and explore the igneous, sedimentary and metamorphic processes of rock formation. Your students will Understand the processes that form igneous, sedimentary and metamorphic rocks. Identify rocks by their physical characteristics. Classify igneous rocks as extrusive or intrusive. Classify sedimentary rocks as clastic, organic or chemical. Classify metamorphic rocks as foliated or nonfoliated. Model the effects of metamorphism on rocks. Relate different types of rocks to the processes of the rock cycle. Class Size: 40 Students. Grades: 7-10.
