Overview

This 3-day lesson series engages 9th-grade Earth/Environmental Science students (all boys in a Middle College setting) in exploring plate tectonics, mantle convection, and earthquake and volcano data using the 5Es instructional model. The lessons align with Common Core State Standards and Next Generation Science Standards, particularly ESS.EES.2.1 and ESS.EES.2.2, emphasizing critical thinking, model use, and data analysis to prepare students for college-level coursework.
