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 is an annotated, topical list of science fiction novels and stories based on more or less accurate astronomy and physics ideas. Learners can read fictional works that involve asteroids, astronomers, black holes, comets, space travel where... (View More)

This is an activity about albedo, which is a measurement of the reflectance of a planetary surface. Learners will classify areas on an image in terms of albedo values and then sketch their own portion of an image from space. These sketches are... (View More)

The 9-session NASA Family Science Night program invites middle school children and their families to discover the wide variety of science, technology, engineering, and mathematics being performed at NASA and in everyday life. Family Science Night... (View More)

Audience: Informal education

Students will learn about NASA's Fermi satellite and gamma ray sources through reading a NASA press release. They will also learn about gamma rays and the electromagnetic spectrum by viewing a NASA eClips video segment. Then, students will use... (View More)

In this activity, students are introduced to light and colored gels (filters). Students make and test predictions about light and color using gels; learn about the importance of gels (filters) to astronomers; then analyze images taken with regular... (View More)

In this activity, students build a photocell detector, and use it to detect different colors of light in a spectrum. Then they place the detector just outside the red region of the visible light spectrum and see that the detector detects the... (View More)

In this activity, students learn that infrared light is reflected in the same manner as visible light. Students align a series of mirrors so that they can turn on a TV with a remote control when the remote is not in a direct line with the TV. As a... (View More)

In this activity, students learn that light carries information. Students also discover that infrared (IR) radiation is a form of light that in some cases behaves like visible light and in other cases behaves very differently. For example, some... (View More)

This interactive illustrates how images from space get to earth and how we interpret the images. Users are encouraged to experiment with images to get a firm grasp of how scientists use color filters to interpret data.
