Students to develop brochures or guides explaining the geologic history of their communities to be used by their local bed and breakfast association. The use of maps and models is incorporated into learning activities throughout the unit. As students move through the unit, they examine sedimentary, igneous, and metamorphic rock samples and learn how they form. Students then learn how rocks are distributed in Earth’s crust and how to read geologic maps and cross sections. By the end of the unit, students should be able to put their acquired knowledge to use, detailing the geologic history of the their communities and also placing this history into the larger perspective of the geologic history of the United States.
