This lesson explores El Nino by looking at sea surface temperature, sea surface height, and wind vectors in order to seek out any correlations there may be among these three variables. It employs group work where different teams work together to analyze a single variable, and then get together in different groups to compare all three variables. The lesson will guide students through data representing ... Full description.

This lesson will connect the idea of the tilt and orbit of the earth (changing of seasons) with monthly changes in snow/ice. Students will evaluate changes in the snow/ice cover from January 2008 to June 2008 and compare to the tilt of the Earth and position in orbit (seasonal change) using monthly Snow/Ice Data from January 2008 to June 2008 from MyNASAData website.

The depletion of the ozone layer is recognized as one of the Earth's most important environmental issues. The Antarctic ozone hole is recognized as one of the most striking indicators of ozone depletion. The location of the ozone hole is generally confined to the latitudes over Antarctica, although there are occasions when the ozone hole can move over lower latitudes locations such as South America. ...

Snow and ice are both precipitation, that is, the processes that remove water from clouds. Clouds, regions of the atmosphere with high relative humidity, are made of droplets of water and perhaps bits of ice. Even though water is much denser than air, these droplets and ice crystals are small enough to be suspended by random upward air motion. When these droplets or crystals join together, gravity ...

In this lesson students will build on knowledge gained in the Hurricane Research lesson and the Hurricane Frequency and Intensity Lesson. Specifically, they will discuss the interaction (pathway) between a specific 'sphere' and the 'event' (hurricane). Working in groups, students will be assigned a specific sphere to look at more closely in relation to hurricanes. When all groups are finished, each ... Full description.

In this lesson, students will examine a historical Category 5 hurricane, Hurricane Rita, that crossed the Gulf of Mexico during September 18-24, 2005. First, they will use the MY NASA DATA Live Access Server to obtain sea surface temperature (SST) data maps of the Gulf of Mexico. Then, they will construct a time series of SST data (line plot) for a location within the path of the hurricane where a ... Full description.

Students will use NASA satellite data to study temperature and snow-ice coverage in the South Beaufort Sea, Alaska. The data can be used to correlate with USGS ground tracking of polar bears, and to relate this to global change, sea ice changes, and polar bear migration. The data can be used to draw conclusions surrounding any migration patterns in the region. Full description.

The Darby Creek watershed encompasses an area of approximately 550 square miles in central Ohio. The Big and Little Darby Creeks are well known for their vast diversity and abundance of aquatic and terrestrial plants and animals. They are home to eighty-six species of fish, five of which are endangered. Forty-one species of freshwater mollusks live in these waters, eight of which are on the Ohio endangered ...

In this lesson, students will examine authentic NASA satellite data to explore how hurricanes extract heat energy from the ocean surface. They will practice finding data via the Internet and make line plots and data maps. Students will understand how hurricanes gain energy from the ocean surface. They will form a hypothesis, compare data parameters and draw conclusions. Full description.

Earth's albedo is the fraction of incoming radiation (sunlight) that is reflected into space. The Earth has an average albedo, which describes how much sunlight is reflected on average for the whole planet and the whole year. The Earth also has a local albedo, which determines how much of the Sun's light is reflected from a particular place at a particular time. The local albedo depends on the particular ...
