This activity will help students better understand and practice estimating percent cloud cover.

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

In this mini lesson, students analyze a bar graph showing the relative forcings from natural and human factors that affect Earth's climate. They use information from this graph to assess the relative importance of these factors.

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.
