Kepler's Laws Orbit Simulator: experiment guide

This browser-based 3d simulation helps you connect orbit shape and orbital speed with Kepler’s three laws. Designed for Grades 7–12, it turns an abstract idea into a model you can control, measure, reset, and test without signing up.

What you can investigate

Explore Ellipses, orbital period, swept area, semi-major axis by changing the available controls and comparing the model’s visual and numerical evidence. Try one variable at a time, then combine changes to test a stronger explanation.

How to use this simulation

1Read the mission and make a prediction before moving a control.
2Change one variable so its effect is easier to identify.
3Run the model and record a value, pattern, or visible change.
4Reset, test a different setup, and explain the result from evidence.

For students, teachers, and independent study

A typical investigation takes 7–12 min. Use it as a lesson demonstration, a guided inquiry activity, a homework experiment, or a quick review. The simulation runs in a modern web browser and does not require an account.

Level: Intermediate
