(14 pages) This is a very cool activity for students of all ages. Most of us are aware that the winter sun and the summer sun are different. We're just not sure exactly how they're different. This activity uses actual data from the U.S. Naval Observatory to illustrate the stunning difference between the summer sun and the winter sun at four U.S. locations. Data for four different cities are provided. Students will plot the Sun's paths as seen from Miami, Cincinnati, Duluth, and Juneau. In addition, another activity requires students to compare Sun altitudes for two northern and two southern hemisphere cities. The findings are surprising. Students might be amazed!
