InterWET was created to help officials and concerned citizens about groundwater resources. Using a case study of the Spring Creek Watershed (central PA), the site gives a multi-layered view on the issues surrounding watershed use and availability. The site uses a series of webpages from three perspectives: a researcher, a conservationist, and a local official. Each page offers interactive lessons ... Full description.

This site presents two case studies regarding the Wheeling Creek area of West Virginia. The scenario asks students to research problems and come up with answers to a ficticious local water board's concerns over water quality in the watershed. The site provides students with extensive, yet easy to understand background information on the following topics: Importance of Water, Water Cycle, Hydrosphere, ... Full description.

The Federal Emergency Management Agency (FEMA) deals with natural hazards such as hurricanes, floods, national security matters, winter storms, etc. in a non-threatening scientifc and fun manner for children. The site includes animations, videos, games, quizzes and questions areas that address hazardous situations that children may face at any given time. Full description.

This is a lesson that enables the student to describe how hurricanes move and change appearance over time through the use of the pubic domain image processing software. Full description.

This learning unit is designed to present a means to examine what factors influence the quality of water in the Chesapeake Bay: population increase, algal blooms, endangered species (shad, oysters and blue crabs), and different watersheds (such as the Susquehanna River Basin) draining into the Chesapeake Bay bringing nutrients and pollution. Students work in groups to take on the role of scientists, ... Full description.

This activity examines many of the reasons why it is important to construct large dams, specifically, the three major dams across the Gunnison River leading into Black Canyon (Colorado). The importance of the dams for irrigation, electrical supply and recreation throughout history is explored. Students will learn about the different types of dam constructions, with pros and cons for each. There is ... Full description.

In this lesson, students create graphs to explore how hurricanes extract heat energy from the ocean surface. It is designed to help students gain knowledge in using the MY NASA DATA Live Access Server (LAS) to specify, download and use a microset of data. Students will make graphs from the data microset, then use the graphs to investigate locations along the track of Hurricane Rita where lowered Sea ... Full description.

This yearbook includes feature articles illustrating how DAAC data are being used to improve live on Earth. NASA's eight Distributed Active Archive Centers (DAAC) located across the U.S. deliver data that underpin research and understanding of the Earth system. The DAACs distribute science data from both heritage and current NASA satellite missions that include NASA in-situ field campaigns and satellite ... Full description.

This activity prepares the student to launch an investigation of the relationship between precipitation and Streamflow for a local watershed. It can enrich a study of the water cycle. Following the step-by-step instruction in this case study, students will locate, download, format, and finally graph one year of Web-based data for these two variables. Included is a graph that highlights the details ... Full description.

This chapter walks users through a technique for documenting change in before-and-after sets of satellite images. The technique can be used for any set of time-series images that are spatially registered to show the exact same area at the same scale. In the chapter, users examine three Landsat images of the Pearl River delta in southeastern China. In these images, users observe changes in land use, ... Full description.
