In this hands-on sequence, students explore how the three major rock types—sedimentary, metamorphic, and igneous—are formed. Using food items and modeling clay as analogs for geological materials, students simulate the processes of pressure, heat, and cooling. This tactile approach helps concrete learners visualize abstract geological timescales and deep-earth processes. By the end of the sequence, students will be able to identify key visual characteristics that signal how a specific rock was made.
