Watch NASA videos about aerosols and volcanic ash.

In this lesson, students will explore the effect of aerosols on sky color and visibility by using an interactive virtual model. 

These six graphs show Ocean Chlorophyll Concentrations from 1998 - 2018 in a variety of locations: East Bering Sea, Gulf of Alaska, California Coast, Southeastern US/Gulf of Mexico, Northeastern US and the Scotian Shelf, and the Hawaiian Islands.

In this lesson, students will explore the effect of aerosols on sky color and visibility by using an interactive virtual model. 

Students use albedo values of common surfaces along with photographic images of Earth taken from the International Space Station to make an argument about specific anthropogenic activities that impact Earth’s albedo.

Students analyze historic plant growth data (i.e., Peak Bloom dates) of Washington, D.C.’s famous cherry blossom trees, as well as atmospheric near surface temperatures as evidence for explaining the phenomena of earlier Peak Blooms in our nation’s capital.

This lesson contains a card sort activity that challenges students to predict relative albedo values of common surfaces.
