Winter, spring, summer, and fall—Earth experiences them all! But what about Mars? Scholars compare the planets in terms of distance, tilt, and rotation during a lesson from PBS's Space series. Great visual models of Earth and Mars, plus...

Use the following lithographs to envision the scale of our solar system. View different models of planets at different scales, an infographic about the relative sizes of the planets and distance from the sun, and images of the largest...

This lesson will develop a map of the solar system in proportion to the distance between the planets. It is 1 of 3 in the series titled "The Solar System."

This page from NASA provides a chart of statistical information on planet Mercury. Its mass, diameter, average temperature, and distance from the Sun are among the characteristics listed.

This site has a data table of statistical information about Mars. Among the things listed are density, diameter, distance from the Sun, and much more.

These hands-on activities are are a great way for students to gain perspective on the relative sizes and distances of each planet, the relationship between the sun and Earth, and much more.

In this activity, "You will investigate the concepts of relative size and distance by creating a basic model of our solar system." Planet printouts are provided and this site contains related links.
