1. The region north of 66½° N latitude is the Arctic Circle. Use the simulator to describe the length of the day during winter, spring, summer, and fall. Answer: Winter Spring Summer Fall (6 points) Score

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. Answer: Latitude (in degrees) Time of Year Rise Position Choose one: – exactly east – north of east – south of east Set Position Choose one: – exactly west – north of west – south of west Maximum Angle of the Sun (in degrees) Length of Day (in hours) 0 winter solstice 0 spring equinox 0 summer solstice 0 fall equinox 40 winter solstice 40 spring equinox 40 summer solstice 40 fall equinox (6 points) Score

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. Answer: Winter solstice Summer solstice Hours of
