Above are graphs representing the times for the sunset, sunrise and solar noon for Grand Rapids, Michigan and Buenos Aires, Argentina. There is also a graph for the shadow length for both locations. The document shows the data that the graphs were created from. Students can be shown these graphs or graphs similar to them and be asked to make conclusions about the type of seasons that would be experienced at the different locations throughout the year. They should see that during the months of June and July, Grand Rapids is experiencing its longest days and Buenos Aires is experiencing its shorter days. Longer days are found during summer, so Grand Rapids is probably experiencing Summer. The Shadow for Grand Rapids is also at its shortest during June, meaning that the angle of the sun is more direct overhead, which is also found in summer. Buenos Aires is experiencing its shortest days during that time, which usually occurs in winter, so in June, Argentina is experiencing winter. This can also be seen in the shadow graph that the shadows are at their longest during June and July which is caused by the sun being less direct overhead. This shows that the angle of the sun above the horizon (caused by the tilt of the Earth) affects the seasons we experience.
