Curated OER
Geometry in Nature
Students examine how the circumference, diameter, and the relationship of Pi of a circle are related. They count the summer rings of a tree to determine its growth.

TE Activity: A Roundabout Way to Mars
Students investigate Hohmann orbit transfers using cardboard and string while focusing on the orbits of Earth and Mars. They look at the planets orbits around the sun and transfer orbit form one planet to another to determine what a...
Curated OER
Minerals
Students explore the concept of minerals. For this minerals lesson, students discuss how cooling affects the size of crystals. Students discuss how the structure of minerals is a tetrahedron. Students discuss the structure of silicates...
