This United States Geological Survey site focuses on water and its properties. The site contains activities for teachers and students, along with pictures, data, maps, and an interactive center where users can give opinions and test their water knowledge. Unique aspects of this site include the sections that contain student work and a picture gallery. There are links to other resources for students, ... Full description.

The New Millennium Observatory (NeMO) is a seafloor observatory off the coast of Oregon, which studies the relationships between submarine volcanic events and the chemistry and distribution of hydrothermal vents and the biologic communities that depend on them. The research activities at NeMO provide an extraordinary educational opportunity, both from the daily reports from expeditions at sea and ... Full description.

The atmosphere is a mixture of gases including nitrogen, oxygen, carbon dioxide and other trace gases. Additionally, the atmosphere contains small, suspended liquid and particle matter called aerosols. Aerosols come from various sources, both natural and anthropogenic (man-made). Aerosols are important to study and monitor because they have direct and indirect effects on regional weather and global ... Full description.

Back in the days of Christopher Columbus, voyages made across bodies of water were dependent upon winds and currents to drive the sailing ships. Thus good navigation routes were often determined by prevailing weather conditions such as the Trade Winds, and then discovered by explorers. In this lesson, students will explore the wind climatology for the Atlantic Ocean basin (as determined by satellite ... 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.

El Nino and La Nina are important temperature fluctuations in surface waters of the tropical Pacific Ocean. In this lesson, students will create maps and line graphs of data to compare the effects of El Nino and La Nina at two different longitudinal locations, but at the same latitude, using sea surface temperature and precipitation from real satellite data. Full description.

Using the Internet as a resource to locate and graph scientific data, students will explore the seasonal changes in precipitation for the Costa Rican Region. They will generate and analyze satellite data for precipitation to identify the two seasons of Costa Rica and relate their importance to the travel industry. Full description.

This lesson is designed to help students gain knowledge in using the MY NASA DATA Live Access Server (LAS) to specify and download a microset of data, then to use the data to create graphs comparing the amount (percentage) of snow cover along selected latitudes. Students will make graphs from the data microset, then use the graphs to investigate the percentage of snow cover by latitude. The lesson ... Full description.

This lesson is designed to help students gain knowledge in using the MY NASA DATA Live Access Server (LAS) to specify and download a microset of data, then to use the data to investigate tropospheric ozone for several US cities. Using the LAS, student-groups will create line-plots of tropospheric ozone for a particular date and city. From that information they will investigate possible trends in ozone ... Full description.

In this lesson, students download cloud coverage and surface data from the NASA CERES S-COOL website student observation database, then use the Excel spreadsheet program to develop plots of the data. Students explore the relationship between cloud coverage and humidity for low-, mid-, and high-level clouds. The lesson provides detailed procedure, related links and sample graphs, follow-up questions ... Full description.
