Lesson Description

Use the pattern of sound to observe transits. Derive Kepler’s Third Law from the data collected within the solar system. Then apply Kepler’s Third Law to extrasolar systems and the search for exoplanets while collecting rare coins along the way.

Central Question

What is the relationship between a planet's distance and its orbital period?

Instructional Objective

Develop and use a model of the solar system to derive Kepler’s Third Law and apply the equation to search for exoplanets in orbit around their stars.


Learning Outcomes

  1. Use a sound diagram to identify patterns that indicate the period of a planet in the solar system
  2. Determine the orbital distance of a planet needed to generate the pattern of sound in a given model.
