 Things to try on the Season Simulator

  1. Move the stick figure so the latitude line is at your home latitude. What happens to the sun's angle (attitude)?
  2. Place the stick figure at Palmer latitude, then at South Salem latitude. Describe what happens.
  3. Slide the red arrow across each month. Watch what happens to the sun's attitude at different latitudes.

How do you think the length of my shadowstick would compare to the length of the shadowsticks in Alaska and New York on Sept. 22? Why?
