This problem-based learning activity uses Hurricane Katrina as the context for students to conduct an Earth system analyses in order the answer the following questions: Are recent increases in the number and strength of hurricanes a result of an increased greenhouse effect and a warmer climate? Or are they the result of a natural cycle? Full description.

This activity explores the potential for climate variability and change to trigger more frequent occurrences of El Nino, and the impacts that could result. Designed to teach through scientific inquiry, the activity seeks to stimulate thought about the long-term impacts of a warmer planet. Through their participation in this activity, students will access information at remote sites using telecommunications, ... Full description.

The Sun heats the Earth, but the Earth also emits some of the heat back into space. The net amount of energy determines not only seasonal weather, but also climate trends. According to NOAA, monthly snow and ice amounts have declined over the past decade. By matching maps of snow and ice amounts with maps of net radiation flux for the same time frame, this lesson will give students the opportunity ... Full description.

This lesson uses NASA satellite data to contrast amounts of cloud coverage over different climate regions in Africa. An an outcome of the lesson, the student will be able to explain how Earth's major air circulations affect global weather patterns and relate local weather patterns to climate as well as identify different climate regions. Students will also describe conditions for cloud formation along ... Full description.

This lesson plan uses NASA Clouds and 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.

Scientists have studied the physical properties of clouds and have developed instruments onboard satellites to characterize the types of clouds they see below. Some satellites have instruments that allow them to measure rainfall as well. For this lesson, students will hypothesize what types of clouds they believe will create the most precipitation (rainfall) over Nashville, TN. Students use the Live ... Full description.

One of the most studied and important ocean currents of the world lies along the eastern coast of the United States and is called the Gulf Stream. It derives its name from its source region of warm water in the Gulf of Mexico. For the past two decades, scientists have been collecting sea surface temperature (SST) data from satellites, buoys and ships in the Gulf Stream and Atlantic Basin. In this ... Full description.

Corals feed on algae that thrive in the sunlit water surrounding a reef. However, when water temperatures get too warm, the algae food source dies and corals turn a whitish color. Through scientific observation, it has been determined that coral bleaching may occur when sea surface temperature (SST) exceeds 30C or 86F for a week or longer. During late 2005, a major coral bleaching event occurred when ... Full description.

The Gulf of Maine Aquarium hosts this two-part activity. The focus is on seasonal changes in the mass balance of the Antarctic Ice Sheet. Part 1 uses an atlas and satellite imagery to examine the geography of the region and the changing boundaries of the ice sheet. Part 2 tracks annual changes in sea ice. There is an animation page showing changes in ice cover around Antarctica during 1991, and links ... Full description.

The majority of Ocean World is devoted to a series of ten reference sections: coral reefs, currents, El Nino, Fisheries, Ice Ages, icebergs, JASON-1 (a satellite), the role of the ocean in weather, satellites and ocean exploration, and waves. Each section culminates with an interactive quiz, links to sources of related real-time data, and a list of additional related links. Also available is a set ... Full description.
