Interactives: The Rock Cycle is a collection of activities, with accompanying readings and animations, that provides information on rock types, the processes that affect rocks and the interrelationships among the three types. In Part 1,Types of Rocks, students read information on igneous, sedimentary and metamorphic rocks, concentrating on the characteristics that can be used to identify these general types. A short quiz that provides immediate feedback concludes this section. In Part 2, How Rocks Change, students read text and view animations that describe the processes that transform rocks from one type to another. The processes discussed in this section are Heat & Pressure, Melting, Cooling, Weathering & Erosion and Compacting & Cementing. Again, this section ends with a brief interactive challenge that provides immediate student feedback. In Part 3, students complete a diagram of the rock cycle that combines the processes studied in Part 2 with all three rock types and magma, creating more of a “rock web” than a simple rock diagram. All questions in this quiz involve one of the physical processes involved in the cycle. There is an additional “Test Your Skills” interactive quiz which teachers can use to assess student knowledge. The site includes an “About This Interactive” page for teachers and a glossary for student use.
