Stories in Stone is an earth science unit that deepens understanding of the processes that lead to the formation of igneous, sedimentary, and metamorphic rocks. Working with a set of ten rock and mineral samples students learn the distinction between rocks and minerals, classify the samples, and attempt to classify “mystery rocks.” They observe formation of salt crystals and make models of crystal shapes. A crystallization experiment, using salol at different temperatures, models processes in the formation of igneous rocks. Unique clay modeling activities with geological narratives provide students with “hands-on” insight into the rock cycle and plate tectonics.
