In this space science activity, learners explore transits and the conditions when a transit may be seen. Learners use models to investigate how a planet's size and distance from its star affects the behavior of transits. Learners also use mathematics to interpret graphs of brightness vs. time to deduce information about planet-star systems. This lesson includes educator instructions, photocopy masters for Transit Light Curves, Option Math for Transit Tracks, Kepler’s 3rd Law graphs, cube root tables, an account of Jeremiah Horrocks' 1639 observation of the transit of Venus, and an answer key for the Transit Tracks Light Curves.
