There are various local and regional climates on the Earth's surface. While the overall climate of the Earth is often the focus of research and discussion, individual local climates are important to consider when thinking of indigenous plants and animals. In this lesson, students will choose two locations, preferably in different climate zones, and compare real NASA satellite data for those two locations. ... Full description.

There are many factors that affect an area's near surface temperature. One factor is the tilt of Earth's axis relative to the sun as it moves in its orbit around the Sun. These changes are due to the orientation of the tilted rotation axis with respect to the Sun. In this lesson, students will compare near surface temperature at the time of the solstices, the astronomical beginning for either summer ... Full description.

The seasons on Earth are caused by the tilt of the Earth on its axis as it revolves around the Sun. The differences in climate along similar latitudes can be explained by local variations in heat transfer, such as sea and land breezes. The absorption of solar radiation by different surface materials also contributes to variations in temperature along similar latitudes. Students will learn to correlate ... Full description.

Solar cells have varying amounts of effectiveness depending on factors such as latitude and cloud coverage. For example, locations with more cloud coverage will produce less solar energy. By comparing the monthly averages of surface downward radiation in various locations around the United States, students can analyze areas that would be more or less beneficial to having solar panels per month. This ... Full description.

Solar radiation (light) strikes Earth's surface throughout the daylight hours. Radiation (heat or infrared) also leaves the Earth during daylight and at night. Averaged over time and space, these downward and upward energy fluxes are equal. If they were not, our planet would gradually heat up or gradually cool down. But the surface of our planet is not simply a mirror for radiation. Some of the incoming ... Full description.

The seasons on Earth are caused by the tilt of the Earth as it rotates on its axis and revolves around the Sun. Students will correlate surface radiation with mean surface temperature of several geographic regions. By observing the graphs of these parameters, students will construct an understanding of the reason for the seasons. 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.

Students will make predictions by linking current scientific satellite data to concerns about global climate change. Using maps of sea surface temperature (SST) and ocean surface winds, students will learn how differential heating of Earth results in circulation patterns in the atmosphere and oceans that globally distribute the heat. Students will learn the relationship between the rotation of Earth ... Full description.

Solar energy is radiant energy that is produced by the Sun. Every day the Sun radiates an enormous amount of energy. How much solar energy a place on Earth receives depends on several conditions. In this lesson, students will explore real NASA satellite data for energy from the Sun and cloud cover for their area to determine if they can harness this solar energy, a renewable energy source, by using ... Full description.

Our atmosphere is warmed by shortwave radiation received from the Sun. Some of the energy is reflected back to space depending on cloud cover and the surface characteristics of Earth. Some of the energy is absorbed by the surface, then re-emitted back to space as longwave radiation. As this occurs, clouds and atmospheric gases can reflect, absorb and re-emit this energy -- the so-called greenhouse ... Full description.
