Mechanical vs. Chemical Weathering Lesson Plan: How Geological Features are Formed

In this lesson plan, which is adaptable for grades 6 through 8, students use BrainPOP resources to investigate the scientific view of how the Earth’s surface is formed. Students will explain the effects of physical processes (plate tectonics, erosion, deposition, volcanic eruption, gravity) on geological features including oceans (composition, currents, and tides.) They will also describe soil as consisting of weathered rocks and decomposed organic material. The lesson includes a free PowerPoint presentation.
