Teaching About Plate Tectonics and Faulting Using Foam Models
Young scientists learn about plate tectonics and the three different types of faults (normal, reverse, and strike-slip) using foam models. The activity also covers common types of locations where these faults are found.
Curated OER
Introduction to Minerals
Young scholars discover how crystal structures go together to create minerals. In this earth science lesson, students work in groups to create 3-dimensional shapes of crystals that they then put together in a compact structure.

Shapetown
Students identify basic geometric shapes. In this geometry lesson, students read the book Shapetown and identify the various shapes from the story. Students are given a sheet and draw part of a town using only shapes.
Curated OER
Protein Puzzles
Learners examine the concept of protein structure. They read an article, construct a three-dimensional model of an insulin protein, take a quiz, conduct Internet research, and answer discussion questions.
