This unit was designed using the three stages of Understanding by Design

In this unit, Middle School students (Grade 6-8) will learn that the Earth’s crust is composed of plates that are moving (Theory of Plate Tectonics), analyze evidence for this theory (continent shapes, fossils, rock formations and ages), and discover that the causes of this movement (convection currents in the mantle) are also responsible for mountain building processes, volcanoes, and earthquakes. The significance of location of landforms (mountains, rift valleys, ocean trenches) and events (earthquakes) are also explained in terms of Plate Tectonics. (Note: This unit assumes students have a working knowledge of density.)
