This Amazing Space science lesson teaches students about the electromagnetic spectrum and how its interpretation enables scientists to gather information about the universe. Computer activities help to explain the wave-energy relationship, and the color-wavelength-temperature relationship. Each section includes questions, 'brain teasers', and reference material for teachers. Full description.

In this lesson, students use a Web-based customized version of ImageJ to examine images of atmospheric ozone levels over the South Pole to determine the months of lowest ozone levels and changes in ozone levels since 1979. Some of the causes for the decline in ozone are introduced. Full description.

In this lesson, learners use WebImage, a Web-based customized version of ImageJ, to investigate changes in snow cover and sea ice in the Northern Hemisphere over a period of 24 years. The images are obtained from satellite measurements of visible and microwave radiation. The lesson follows from Snow and Ice: A Hemispherical View. Full description.

In this article, The Why Files examines our star, the Sun, and its features. It discusses how the Sun creates energy through fusion and the solar maximum that occurs every 11 years. Solar wind, solar prominences, solar flares, and sunspots are all described and explained. There are sections on sunquakes, which explains how we use vibration data to tell us about the Sun, on the Sun's magnetic field, ... Full description.
