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

Use the Earth System Data Explorer to analyze data and make a claim about which 2018 eruption was larger, Kilauea, HI or Ambae Island, Vanuatu.

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.
