Students use a dipole magnet and compass to model and map Earth's magnetic field. They then induce a magnetic field to represent a Ring Current in order to observe the response to a fluctuating electric current caused by a solar storm. The lesson... (View More)

This textbook chapter traces the historical development of the modern scientific understanding of light, and reviews the electromagnetic spectrum and the Earth's atmospheric shield. The resource includes links to current news articles, and a suite... (View More)

This book offers an introduction to the electromagnetic spectrum using examples of data from a variety of NASA missions and satellite technologies. The 84 problem sets included allow students to explore the concepts of waves, wavelength, frequency,... (View More)

Audience: Middle school, High school
Materials Cost: Free

This is an activity about magnetism and magnetic forces. Learners will explore objects to which a magnet is attracted or repelled and record information in a learning log. Additionally, learners will identify magnetic devices or phenomena they... (View More)

Audience: High school

This is an activity about depicting the relative strength of magnetic fields using field line density. Learners will use the magnetic field line drawing of six magnetic poles created in a previous activity and identify the areas of strong, weak, and... (View More)

Audience: High school

This is an activity about depicting magnetic fields. Learners will observe two provided drawings of magnetic field line patterns for bar magnets in simple orientations of like and unlike polarities and carefully draw the field lines for both... (View More)

Audience: High 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: High 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: High school

This is an activity about depicting magnetic polarity. Learners will observe several provided drawings of magnetic field line patterns for bar magnets in simple orientations of like and unlike polarities and carefully draw the field lines and depict... (View More)

Audience: High school

Students investigate magnetic fields in two and three dimensions, and compare the magnetic field of a pulsar to that of the Earth and other astronomical objects. This is Activity 3 of the Supernova Educator Guide developed by the XMM-Newton and... (View More)
