The Moon has no atmosphere or magnetic field. Most rocks on the surface of the Moon seem to be between 4.5 and 3 billion years old, older than those usually found on Earth. Thus the Moon provides evidence about the early history of our solar system.
"Fast Facts: The Moon" is a table that lists the Moon's age, location, average distance from Earth, diameter, orbital period around Earth, mass, and distinguishing features. A picture of the Moon is included.
Use this resource as:
A source of information. Read the table to find out about this object.
A large-number recognition and ordering activity. Have students review several Fast Fact moon tables, including this one. Have students read the tables to find each object's mass. Then ask them to arrange the objects according to their mass, from smallest to largest. Students also can arrange the objects according to their diameter.
A math activity. Use Newton's law of gravitation, the distance between Io and Jupiter, and the masses of the two objects to determine the gravitational force between them. (Recommended for grades 10-12)
An inquiry tool. Have students write down questions they would like answered about the image and the information in the Fast Facts table.
An engagement tool. Involve students in a discussion.
