In this activity, students explore three indicators of drought are: soil moisture, lack of precipitation, and decreased streamflows. Students investigate each of these parameters develop a sense for the effects of drought on land.

The purpose of this activity is for students to create a desktop soil profile based on the biome region of the United States where your school is located.

In this activity, you will use an inexpensive spectrophotometer* to test how light at different visible wavelengths (blue, green, red) is transmitted, or absorbed, through four different colored water samples.

Students will review the NASA Space Place video, "Tectonic Forces", and answer questions about tectonic plates.

Students will describe the changes in a newly-formed volcanic island over the first three years of its life.  

Watch NASA videos about aerosols and volcanic ash.
