This is an activity about electromagnetism. Using a battery and a length of wire, learners will construct an electromagnet and investigate the number of paperclips the electromagnet can hold for an electromagnet with twenty loops of wire versus one... (View More)

Audience: Elementary school

This is an activity about magnetic fields. Using iron filings, learners will observe magnets in various arrangements to investigate the magnetic field lines of force. This information is then related to magnetic loops on the Sun's surface and the... (View More)

Audience: Elementary school

This is an activity about Earth's magnetosphere. Learners will use a magnet, simulating Earth's protective magnetosphere, and observe what occurs when iron filings, simulating the solar wind, blow past and encounter the magnet's field. This is the... (View More)

Audience: Elementary school

This is an activity about magnetism and magnetic forces. Learners will explore objects to which a magnet is attracted or repelled, and investigate the attractive and repulsive forces of two like and two unlike magnetic poles. This is the first... (View More)

Audience: Elementary school

This is an activity about magnetic induction. Learners will induce a flow of electricity in a wire using a moving bar magnet and measure this flow using a galvanometer, or Am meter. This is the fifth activity in the Exploring the Earth's Magnetic... (View More)

Audience: Elementary school

This is an activity about how impacts in space increase the heat of planetary bodies. Learners will demonstrate the conversion of kinetic energy (energy of motion) to heat (thermal) energy by hammering a nail and feeling its temperature increase.... (View More)

Audience: Middle school

This is an activity about gravity in space. Learners will use water in a cup to demonstrate “weightless” conditions in free-fall. This activity is part of "Ways of Seeing," an interactive, educational CD-ROM from NASA's Cassini Program. The... (View More)

Audience: Middle school

This is an activity about orbital speed. Learners will create an analogy to planetary orbits using weights on a string that demonstrates the farther a moon is from a planet (or a planet from the Sun), the slower its orbital speed. This activity is... (View More)
