Students investigate the importance of water historically and in their daily lives and examine the nature of water as a limited resource. Working in groups, they will list the various uses of water, discuss why water is a limited resource, research technological systems that are intended to use water as productively as possible, and create "How It Works" posters for presentation to the class. The ... Full description.

Flowing water from rivers and streams is a valuable and plentiful energy resource that people learned to use centuries ago to operate the machinery that was important to their livelihoods. This page features diagrams (some animated) that show the three main principles of water; various types of water wheels; and the modern hydroelectric turbine. There are also animations of various types of mills ... Full description.

This is the Image for Magnetopause-to-Auroral Global Exploration (IMAGE) archive of weekly math, science, reading and art problems. New problems involving near-Earth space technology are emailed to participating teachers each week on Tuesday. The problems can be used in related lessons or as extra credit assignments. This web page is part of the outreach program of the IMAGE Satellite team to give ... Full description.

This website is part of the Space Telescope Science Institute, and contains a set of interactive, web-based activities and lessons designed for classroom use. Topics include the Hubble Space Telescope, galaxies, comets, black holes, light, and the solar system. Full description.

This interactive diagram allows the user to follow a drop of water from the source through the treatment process. Water may be treated differently in different communities depending on the quality of the water which enters the plant. Groundwater is water located under ground and typically requires less treatment than water from lakes, rivers, and streams. Users are invited to click on each treatment ... Full description.

In this lesson plan students will learn the basics about how tornadoes are formed, and where and when they are most likely to occur. They will then study the current research on tornadoes and explore how scientists are trying to predict them. They will learn about the equipment storm chasers use to study tornadoes and will develop their own research plans. Full description.

This resource includes a classroom activity, background information and a set of temperature and surface pressure data from the Pathfinder Lander. Students analyze data on temperature and pressure graphs from the first 30 days of the Pathfinder Mission to determine whether water could have existed under these conditions. A set of 15 images is also available, which can be reproduced on a photocopier ... Full description.

In this activity, students download NASA Hubble Space Telescope (HST) images of the Martian polar ice caps in summer and winter. Using image processing techniques, students measure and compare various images of the changing Martian and Earth polar ice caps. By completing this activity, they will understand that the sizes of the polar ice caps on Earth and Mars depend on the lengths of the seasons. ... Full description.

This lesson plan uses NASA satellite data to contrast amounts of cloud coverage over different climate regions in Africa. It introduces the circulation pattern of Hadley Cells and the band of convergence and convection called the Intertropical Convergence Zone (ITCZ). The lesson also discusses how frequent cloud cover and precipitation occur along the Intertropical Convergence Zone (ITCZ) and how ... Full description.

This lesson plan uses NASA Clouds and the Earth's Radiant Energy System (CERES) instrument percent coverage surface data with a world map to locate landmasses and bodies of water at the Earth's Equator. When using satellites to study Earth system processes, especially atmospheric processes, it is important to know what is the background that one is seeing on the Earth. This lesson provides an introduction ... Full description.
