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

Compare images from two volcanic eruptions in the Kuril Islands which occurred ten years apart and complete a graphic organizer for impacts on different Earth spheres. 

Watch NASA videos about aerosols and volcanic ash.

Learn about volcanic ash and watch a visualization of the Calbuco volcano to see how ash travels around the world. 

Students will analyze how air pollution may be transported over time. Students will also differentiate between sources of air pollution and describe how air pollution interacts with the Earth System.
