In this activity students will make observations about the objects, size, distance, and motion of the Sun, Earth, and Moon during a solar eclipse and manipulate slides to show the relationships.

This interactive takes students through the basic mechanics of a solar eclipse, using a NASA Space Place Handout, including an optional eclipse art activity.

In this activity students will calculate the ratio of the size of the sun to the moon and the distance of the sun and moon from Earth to determine the type of solar eclipse possible.

Students will identify and describe the relationship between land cover classification and surface temperature as they relate to the urban heat island effect. Students will also describe patterns between population density and the locations of urban heat islands. 

Students observe the surface temperatures of a variety of surface types found in a suburban environment.

Students interpret a graph of surface temperatures taken from city districts and other types of communities.

In this interactive, students will explore safe methods for viewing the Sun at home or in the classroom, including using solar eclipse glasses and a pinhole projector. The interactive includes a video that explains how the projector works and how to build one.

After learning about the different characteristics of satellite data, students will describe the advantages and disadvantages of using two different satellites to study the Urban Heat Island Effect.  

Students will analyze how surface (skin) temperatures vary across a community and determine what factors contribute to this variation. Students will describe how human activity can affect the local environment. 

Students will analyze a line graph that shows how the surface temperature and air temperature values change over the course of 24 hours.
