2.

Use the simulator to complete the table. Use the angle measurements on the left side of
the dome to get the maximum angle of the sun. You don?t have to be exact, but you should
be within 5? of the correct answer. Estimate the length of the day to the nearest hour.

3.

Show how the length of day changes with latitude by plotting the following points. Use
the table below as a graph and place an X in the box where you want to plot a data
point. For example, if you find that a day is 10 hours long at 30? N latitude, represent this
data with an X in the box where 10 hours meets 30 degrees. (You may use a graphing
program like Excel if you prefer.) If you are able to print, connect the points.

4.

Based on your observations, describe how the length of day is affected by latitude in the
summer and in the winter. In your explanation, explain which latitudes are affected most by
the seasonal change and which latitudes are affected least.

5.

Measure the length of the day on the spring and fall equinoxes for latitudes 0, 15, 30,
45, 60, 75, and 90. With the exception of the North and South poles,

Score

(a) What can you say about the length of day for the fall and spring equinoxes?
(b) What happens above 66?? (the Arctic Circle) on the equinoxes?
(c) Where does the sun rise and set on the equinoxes?
