Space Unit: Modeling Gravity

Use a computer simulation to observe how gravity is responsible for the motions within our Solar System. By modifying the distance between objects and the mass of objects, students are able to observe how these variables affect the orbital periods of planets in our Solar System. Extending this concept, students are able to calculate the mass of the Sun. Students are then asked to develop and use a model to describe the role of gravity in the motions within galaxies and solar systems.

Space Unit: A Year Viewed from Space

Each year on Earth, we observe patterns of changing temperatures, daylight hours, and seasons. In this activity, you will use a computer simulation to model Earth’s orbit around the Sun to help understand why we observe these patterns.

Space Unit: Moon Phases

Use a computer simulation that will allow you to observe the Moon’s orbit around Earth from a different point of view. In this case, your point of view will be looking down on the Earth–Moon system from out in space.

Geology Unit: Plate Boundaries

Through this computer simulation, students investigate how Earth’s surface changes over time due to geological processes caused by plate motion. Students analyze and interpret data from the simulation to identify the similarities and differences between the geological processes that happen at the three plate boundaries.
