In this lesson, students will learn Kepler's three laws of planetary motion and learn about the properties of ellipses. The lesson includes an activity in which they construct the orbit of a planet, and use Kepler's third law to calculate its period of revolution. Objectives, background information, a materials list, instructions, and a student worksheet are included. Full description.

This online pamphlet discusses the concept of geologic time. Topics include the relative and radiometric time scales, the use of index fossils in making age determinations, and current thinking on the age of the Earth. Full description.
