Teaching Techniques and Tools

The PARK Teachers Geology resource site includes several teaching tools designed to make an earth science unit engaging for secondary education students. To begin a student inquiry of our essential question, ”How do I recognize geologic change in my environment?”, click on the Magic Windows button on right side of the screen. To use a constructivist approach while introducing the rocks of the Franciscan Complex, click on Edible Geology. The Geo-speak button brings you to links for I Have Tectonics and Geo-Lingo Bingo materials. Both are participatory, fast-paced reviews of the vocabulary-rich language of plate tectonics. To model the geologic assembling of the Franciscan Complex with a sandwich cookie, click on Cookie Tectonics. And to sharpen your rock identification skills and assemble a Cretaceous Period subduction zone, play our online Subduction Construction game by clicking here. While all of these tools are part of the PARK Teachers Geology resource site, you may see many opportunities to adapt these lessons to your specific science teaching needs. Enjoy!

If you are a middle school earth science teacher from a school in the San Francisco Bay Area, your class can participate in Rocks on the Move, a curriculum-based, field geology program in the Golden Gate National Parks which includes these teaching tools. Program information is available at Rocks on the Move.
