Students will examine data in several formats in order to determine the presence or absence of seasonal variability in tropospheric nitrogen dioxide (NO2) concentrations. The dataset used in this lesson is monthly averages of NO2 as measured from NASA's EOS Aura spacecraft. Full description.

This description of the El Nino pattern in the eastern Pacific is from NASA's Earth Science Enterprise. In addition to text and diagrams, it provides three weather related activities for lab or classroom. Full description.

The purpose of this resource is to understand that physical factors - temperature and precipitation - limit the growth of vegetative ecosystems. Students observe and record seasonal changes in their local study site. They establish that these phenomena follow annual cycles and conclude the activity by creating displays that illustrate the repeating pattern associated with the appearance and disappearance ...

This lesson uses NASA satellite data to correlate cloud cover over Africa to the solar declination. The student will access NASA data using the MY NASA DATA Live Access Server and import the data into Excel spreadsheet software. The student will identify the relationship between solar declination and the four seasons and relate seasonal solar radiation patterns to cloud formation. The four seasons ... Full description.

This easy but effective lesson uses NASA CERES satellite percent coverage surface data along with a world map and asks students to locate landmasses and bodies of water at Earth's Equator. Students will map locations using latitude and longitude coordinates. Using the microset of satellite data included with the lesson to investigate surface characteristics, students will apply percentage to determine ... Full description.
