This is a unit of 8 sessions about the Sun-Earth system. Learners will construct a model to show the relative size and scale of the Sun-Earth system, investigate the visible and electromagnetic spectrums, discuss solar flares and solar weather,... (View More)

Audience: Middle 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)

In this lesson, students observe the surface of rotating potatoes to help them understand how astronomers can sometimes determine the shape of asteroids from variations in reflective brightness.

This 28-page coloring and activity book includes general information on X-ray astronomy, Chandra and the STS-93 mission. It also looks at black holes, supernovas, galaxy clusters and more. Each image is accompanied by a summary of information.... (View More)

This is a hands-on lab activity about the composition of salt. Learners will explain the general relationship between an element's Periodic Table Group Number and its tendency to gain or lose electron(s), and explain the difference between molecular... (View More)

This is a lesson about the formation of glaciers, ice layering and stratigraphy, and the cryosphere and cryobotics. Learners will collect evidence of layering, explore the science story that layering tells, study snow and ice for insights into... (View More)

In this activity, identified as the capstone activity, students will be asked to examine and analyze spectra from a past mission and compare it to simulations of data from future missions, including Suzaku. A thorough comparison will show better... (View More)

This is a lesson about water and water-ice. Learners will explore the molecular geometry and mechanics of ice. They will create a model of H2O, investigate its molecular structure and its consistent shape. Faraday's experiment is used as background.... (View More)
