Fixed-Pace Course





In this course, students explore the planet Earth, its history, and the physical processes that continue to shape it. Major topics include the Earth’s origins and geologic time, plate tectonics and seismology, the formation of rocks and minerals, volcanism, weathering and erosion, glaciers, deserts, beaches and the ocean floor, rivers, floods and groundwater, and fossils and their relationship to Earth’s past. Students will deepen their understanding and hone their scientific problem-solving through participation in hands-on labs, group projects, virtual field trips, and (where practical) on-site experiences.

Completion of this course requires regular access to a laptop or desktop computer with working microphone and webcam, as well as a reliable internet connection.

This Fixed-Paced course incorporates a blend of synchronous and asynchronous elements. Students and teacher meet live via zoom on a regular weekly schedule. In addition, students complete coursework including guided readings, interactive videos, text and video-based discussion threads, problem sets, individual and collaborative projects, and so on. While these activities are time-flexible, teachers sequence them with weekly deadlines to help students keep on track and encourage and support the development of productive time management skills.
