STEM Learning Module:

Ocean Silicate Geology

Using marshmallow modeling tools, in this activity students will model the formation of silicates–the family of minerals that make up more than 90% of the Earth’s crust. Silicates range from mafic to felsic. And since not all silicates are made equal, the composition of each of these minerals varies greatly on the depth within the Earth.

STEM Learning Module:

Tectonic Plates

Build students' understanding of boundary types and tectonic plate movements through three activities: modeling plate boundaries with graham crackers and frosting, video analysis, and analyzing real-world earthquake data to make predictions.

Tectonic Plates Teaching Animation

Convection, the movement of fluid beneath Earth's crust, drives the planet's tectonic plates. This process can result in seafloor spreading, which can result in the formation of new areas of oceanic crust.
