Eighth graders draw the paths of the planets in the solar system. In this astronomy activity, 8th graders calculate speed of objects using distance and time information. They research about the work of scientists in the 16th and 17th...

Introduce your physics or astronomy class to Kepler's laws of planetary motion with this straightforward learning exercise. It covers the basic concepts of each and has learners answer questions to demonstrate their grasp on them. You...

Looking for a terrific lesson on the phases of the moon that has lots of good worksheets? With two excellent websites are embedded in the plan, the activity is sure to spark some interest in your astronomy unit. Some common...

Learners construct a solar system model. In this space science instructional activity, students calculate the eccentricity of a planet's orbit. They calculate the period of a planet's revolution using Kepler's formula.

The class examines graphs in the form r = F(¿¿) in polar coordinates (r, ¿¿), in particular with the circle, ellipse and other conic sections. They determine the nature of an ellipse by studying the role of the semimajor axis and...

Students identify the main components of the solar system. In this earth science lesson, students order the planets according to their distances from the Sun. They differentiate planets from dwarf planets.

Students research the two opposing views and biographical information about Ptolemy and Copernicus in order to be familiar with the societal viewpoints that influenced the thinking of these two scientists. Students role-play supporters...

Learners explain that planets actually orbit the center of gravity of the solar system, and that distant planets may be detected by motions of their central star around the centers of gravity of their planetary systems.

At this site from the Astronomy Department of Cornell University, Kepler's three laws of planetary motion are stated. There are brief explanations of each, along with links to additional information on related subjects.

An outstanding page describing Kepler's three laws of planetary motion.
