• Mimic real-world geological procedures.
• Investigate careers in the geologic sciences.
Students are tasked with creating clay geologic models that display stratigraphic layers with embedded “fossils” and “mineral deposits.” During the hands-on building phase of the strata, students are assigned the roles of chief geologist, sedimentologist, paleontologist, and geologic historian. Students trade models with classmates and a core sampling method is applied to investigate the Earth history of the other group’s model. Then, students extend the application of stratigraphy to a larger landscape, using a model of a mountain and valley, where they compare and discuss the variability of core samples. The activities in this kit may be performed in one or two 45-minute class periods.
Kit includes: clay, corers, the mountain model, beads, cups, and teacher’s guide.
