Students in Rowann Hoy’s sixth grade science class at Polk County Middle School recently explored the concept of plate tectonics with Rice Krispie treats, graham crackers and orange frosting.

Students used the food products to model different types of lithospheric crust, the Rice Krispie being a continental plate and the graham cracker being the more dense oceanic plate. The frosting represented the molten rock of the upper mantle.

Students used Chromebooks to take pictures of their models. They will then use those photos to create a poster in Google Drawings that explains how the movement of the plates creates geologic features such as mountains and events such as earthquakes.
