This lesson is intended to make students aware of the need to respect their environment and its natural resources. They will apply that knowledge in developing an "ecologically sound" city. Using an outline, they will design a city that has ecological laws, power source(s) for lights and heat, a river, two industries, and homes for its population. Full description.

This activity has students explore the role that forests play in their own lives by listing everyday products made from trees. They use the Internet to find as many uses for trees as possible in order to develop a class list that should include foods from trees, products derived from all parts of a tree, environmental benefits of trees, and recreational uses of trees. Students are then asked to imagine ... Full description.

Most people today get their water from public utility companies, who obtain it from a natural source. Some of our water comes from surface water such as lakes and rivers. Other utility companies get water from underground sources (rock, clay, sand, gravel) called aquifers. Public utility companies must clean this water to make it safe. This process is called water treatment. This lesson has students ... Full description.

The purpose of this lesson is to examine the role of technology in identifying and tracking hurricanes. It is the second in a two-part series on the science of hurricanes and the kinds of technology being used to identify and track them. Students broaden their study by exploring how technology and science are used today to identify, measure, and track powerful tropical storms to better warn and secure ... Full description.

This lesson allows students to compare and contrast three NASA satellites: The Extreme Ultraviolet Explorer (EUVE), The Cosmic Background Explorer (COBE), and the Hubble Space Telescope (HST). The lesson includes access to data and images from these three NASA astronomy satellites, contrasting the way the sky appears in three very different electromagnetic wavelengths or colors of light. Other satellite ... Full description.

At this site, students learn about the history of Earth imaging and the Landsat satellite program. They develop interpretation skills as they play a game that involves inferring the subjects of various Landsat images. This lesson will help students to be able to show understanding of the history and development of Earth sensing, describe Landsat and its role in modern Earth imaging, and use knowledge ...

This activity will help students to understand and explain where drinking water comes from and where wastewater goes once it leaves the home, as well as how the water we use fits into the water cycle. It is based on a story that describes the journey of a water drop from the well to the septic leaching field of a rural system. In a conversation with a little girl, the drop also describes a journey ... Full description.

These activities allow students to explore many different ways to measure and record time. The most important points are that almost any regular, predictable phenomenon can be used to record the passage of time and orderly patterns of these phenomena help to construct useful frames of reference from which calendars evolved and are still evolving. In addition, any proposed calendar must be compatible ... Full description.

This resource is part of the Science Education Gateway (SEGway) project, funded by NASA, which is a national consortium of scientists, museums, and educators working together to bring the latest science to students, teachers, and the general public. Students learn about the history of Earth imaging, and the LANDSAT satellite program. They read illustrated pages about the history and development of ... Full description.
