Using a model of a planet transiting a star, students learn what a transit is, under what conditions a transit may be seen, and what effects a planet’s size and distance from its star have on transit behavior. Students will interpret graphs, derived from actual Kepler mission transit data, of brightness vs. time to deduce characteristics of a star-planet system. Two methods for data interpretation are offered in the lesson, and are adaptable for middle and high school students. http://bit.ly/stR2rk
