ESS has fantastic, educational and fun introductory classes to get you into earth sciences. Many of these provide hands on learning experiences and opportunities to get outside and see geology in action. Introduction to Geology and Societal Impacts (ESS 101), taught by Terry Swanson, is taken by thousands of students every year. (Terry has won four distinguished teaching awards!)
There are many other offerings for those interested in volcanoes, geologic hazards, climate change, dinosaurs, glaciers, and more. For more about our classes, and more advanced offerings, go to the ESS Course Catalog (linked below).
