Lesson Title: Finding Earth-Like Planets
Description
This lesson combines activities used to provide students with an understanding on how extra-solar and Earth-like planets are detected.
Objectives
Students will:
• Detect a slight flicker when a small ball passes in front of a light bulb illustrating how astronomers detect extra-solar planets as they pass in front of stars.
• Simulate how light collected from a space object converts into binary data and reconverts into an image of the object.

Lesson Activities and Sequence-
Detecting Planet Transits
This lesson incorporates activities that help students understand how astronomers can detect extra-solar planets by noting dimness in the total light output of a star by using a light bulb from a table lamp and a small bead attached to a string. A student moves the ball on a string in front of the light, which is known by astronomers as a "transit." Other students should be able to detect a "flicker" or slight dimness of the total light output from the light bulb.
- Count Your Lucky Stars
Students will readily understand that the number of stars in the galaxy is truly astronomical, not to mention the total number of stars in the universe.
- Paint by Numbers
The Kepler mission's goal is to detect Earth-like planets within our galaxy and acquire images of planetary transits by possible Earth-like planets around stars. Students will use printed grids to demonstrate how digital imagery is deciphered.
