Students in Ms. Lake’s sixth grade class learned about the Plate tectonics theory which deals with the dynamics of Earth’s outer shell (the lithosphere) that has revolutionized Earth Science by providing a uniform context for understanding mountain-building, volcanoes, and earthquakes as well as the evolution of the Earth’s surface and reconstruction in past continents and oceans.
Students used fruit roll ups to represent the oceanic crust; graham crackers to represent the continental crust; and icing to represent the mantle. By manipulating the graham crackers over the icing or the oceanic crust, students were able to see how changes affect Earth. They learned about divergent, and convergent, boundaries and how the earth reacts when these events occur.
At the end of the activity, students were able to eat the graham crackers, icing, and fruit roll ups for a reward!
