The International Ice Patrol is a branch of the United States Coast Guard. They monitor iceberg danger near the Grand Banks of Newfoundland, and provide the limits of all known ice to the maritime community. This kids page provides an illustrated story of the life cycle of icebergs, as well as a list of questions and answers about icebergs in general. There is also a set of links to other sites that ...

This resource provides information on isostasy and the effects of glaciation on the Earth's lithosphere. The descriptions and scientific illustrations demonstrate how glaciers and the growth of continental ice sheets can put pressure on the Earth's crust, causing local and regional-scale depressions of the lithosphere. As the ice thins or decays, this pressure is released, resulting in an isostatic ... Full description.

In this activity, younger students enact the process by which precipitation (rain, snow, and hail) falls on an area and becomes standing water, run-off, or groundwater. They will learn general information about precipitation processes, aquifers, and the importance of clean groundwater. Full description.

This site provides information about rivers, coasts, and the processes affecting them. Students can view an animation of the water cycle, read about how rivers and coasts change, learn about estuaries, and view information on how rivers, coasts, and other water features influence people's lives. Glossaries and a teacher's page offering lesson plans, worksheets, and links to additional sites are also ... Full description.

This site uses a picture of a covered swimming pool as an example of a watershed and describes real-world watersheds and their processes, including precipitation, infiltration, evaporation, transpiration, and storage. Links to an interactive rainfall calculator and to related websites are included. Full description.

This site describes how snow and ice runoff become surface water and emphasizes how runoff from snowmelt is a major component of the global movement of water. A hydrograph from the U.S. Geological Survey shows a four-year time series of streamflow and illustrates how runoff from snowmelt affects the daily mean values, particularly at certain times of the year. Full description.

Students often hear that winters were colder or had more snow in the past. This activity will help them to determine if this is a true or accurate statement for their location. Students will access historic weather information from NOAA and NASA internet resources. They will determine changes in average temperatures, precipitation and cloud cover over time from data and relate global changes to local ... Full description.

This lesson is designed to help students gain knowledge in graphing a microset of data, then using the graphs to investigate trends in cloud coverage over a given locale. Students are provided content-related activities to enhance background knowledge in cloud types, and then are provided detailed instructions on how to download data from the MY NASA DATA Live Access Server (LAS) and to use Excel ... 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.

This national watershed education program is designed to involve young people in local environmental service projects. Visitors can download easy to follow Action Guides that show how to organize and carry out effective action-oriented water projects for youth groups or classes by learning about local watershed issues, investigating what needs to be done, enlisting the help of experts, and planning ...
