This Web site features a daily image of an unusual aspect of the Earth's system. Each image includes a description, when and where it occurred, and other information. Search the archive by keyword or browse by topic going back to 2000. Full description.

The Global Climate Animations site contains animations of the Earth's climate system for educational and research purposes. The animations show the climatology of the seasonal cycle for selected climate variables for the time period 1959-1997, based on data from the NCEP/NCAR 40-Year Reanalysis Project. The individual frames in each animation show the map pattern of the long-term monthly averages ... Full description.

This field activity has two parts: Elementary school students are asked to draw and verbally describe clouds and are given web access to cloud pictures. High school students are taken outdoors to describe cloud height, shape, and cover; and wind speed before answering questions. The activity is part of the Atmospheric Visualization Collection (AVC), which focuses on data from the Atmospheric Radiation ... Full description.

This applet simulates the difficult concepts of adiabatic processes. A leaf visually symbolizes a parcel of air rising over a mountain. Users are allowed to vary the beginning temperature and vapor-pressure of the parcel of air, and the relative wind speed as it moves up and over a mountain. Graphs then display temperature verus altitude and vapor pressure as the leaf rises and falls. A series of ... Full description.

This website provides real-time and forecast weather maps and data for the United States. The Satellite section contains satellite weather images from the GOES 8 and GOES 10 satellites, the Radar section contains radar weather images from NEXRAD radars, the Surface Data section contains plots of various weather conditions (temperatures, winds, pressure, precipitation), and the Upper Air section plots ...

Weather or Not? is part of an online series of modules entitled Exploring the Environment. Emphasizing an integrated approach to environmental Earth Science education through problem-based learning, this module asks students to monitor the current weather and make predictions for up to a week. Using satellite imagery and monitoring resources, students predict the weather for an up-coming event of ... Full description.

This lesson plan is part of the DiscoverySchool.com lesson plan library for grades K-5. It focuses on basic information about the weather and how different weather maps depict conditions. Included are objectives, materials, procedures, discussion questions, evaluation ideas, suggested readings, and vocabulary. There are videos available to order which complement this lesson, and links to teaching ... Full description.

This activity is designed to give students an understanding of how to forecast weather and how to use weather reports for their personal benefit. They will be able to tell what weather is, read weather instruments, understand basic cloud formations in relation to the weather, and make forecasts for two days in advance. Full description.

This website contains summaries and lessons about various aspects of weather. This includes the seasons, types of clouds, air, winds, global warming, hurricanes, tornadoes and lightning. Worksheets are provided to accompany the lesson themes. Full description.

This applet provides a simulation of the type of precipitation that results from adjusting the temperature (dry bulb and wet bulb) at different altitudes. An updraft in the cloud can be produced in order to see its influence on precipitation. The precipitation types that are simulated include snowflakes/ice crystals, supercooled droplets, raindrops, drizzle, sleet, snow grains, and freezing rain or ... Full description.
