Virial Theorem Lesson
Ninth graders describe how equilibrium can occur as the balance of two effects. They model the stability of elliptical galaxies based on how fast stars within the galaxy are moving.
Curated OER
Earth's Orbit Lesson
Tenth graders devise a computational model to explore how the orbit of the Earth might change if its velocity were different. Using accurately recorded data, 10th graders defend a scientific argument.
Curated OER
Collisions Lesson
Tenth graders explore the role that collisions and near collisions of galaxies play in determining the shape of galaxies. They model the collision of disk shaped and spherically shaped galaxies.
Curated OER
Investigation 6 - Celestial Model
Third graders investigate why stars appear to move across the night sky.

Students discuss the application of frames of reference to an airplane flying with a constant velocity v through the air.
Curated OER
Airplane flight
Students learn the basic concepts about airplane flight. They learn the reason jetliner wings are swept back and why jet engines have replaced propellers in high-speed flight.
Curated OER
Pilots, Drivers, and Captains
Students listen to the song, The Wheels on the Bus, then change the words for a boat.
