This lesson is part of a larger Earth science unit that combines the concepts of the rock cycle and the water cycle and how they interact to change landforms. The authors refer to it as the “make it and then break it” unit. They spend half the unit making metamorphic, sedimentary, and igneous rock models, and the second half of the unit weathering and eroding their models and other rocks. Students use the lessons learned to answer an open-ended question describing the process of weathering. They also make decisions regarding the chemical and mechanical weathering on monuments and buildings.
