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

This activity is one of a series in the collection, The Potential Consequences of Climate Variability and Change activities. 

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.
