This document outlines the objectives, content, activities, and evaluation for four classroom sessions on plate tectonics and earthquake epicenters. The sessions aim to teach students about the relationship between volcanoes, earthquake epicenters, and mountain ranges. Students will learn about plate tectonics and how to use triangulation to locate an earthquake epicenter on a map. Assessment methods include a pre-assessment quiz, board work, and activities having students apply triangulation to find epicenters. The final day will include a reflection on what understanding of plate tectonics reveals.
