This instructional packet is one of 14 school environmental education programs developed for use in the classroom and at the Dahlem Environmental Education Center (DEEC) of the Jackson Community College (Michigan). Provided in the packet are pre-trip activities, field trip activities, and post-trip activities which focus on various geological concepts. Strategies for using these activities with fifth grade students are also provided. The pre-trip activities focus on: (1) igneous, metamorphic, and sedimentary rocks; (2) the rock cycle; and (3) weathering and erosion. These and other geological concepts are then reinforced during the indoor and outdoor activities conducted at the DEEC. Instructions and objectives for these activities are provided in a separate field trip guide. The post-trip activities include exploring geology at the school site and examining the effects of Mount St. Helens, and looking for geology in the news. (JN)
