As Earth goes through its different seasons, patterns of changes in shadows and temperature emerge. Let's investigate how this occurs.



  • Flashlight (one for every 2 students)
  • An object (such as a water bottle, whiteboard eraser, etc)
  • Journal


  1. Note: Dim lights for better results.
  2. Set object on desk.
  3. Shine the flashlight directly over object and observe the shadow.
  4. Move the flashlight so that it is slightly angled and observe the shadow.
  5. Shine the flashlight so it is coming from the side and observe the shadow.
  6. In Journal: If the flashlight represents the sun and the object represents the earth, what is the relationship between the angle of the sun and the size of the shadow?
Drag over the box and compare your journal entry with the answer.
During the year the angle at which the sun’s ray hit the earth changes from direct to slanting which causes the size of the shadows to change. The more direct the sun’s rays the shorter the shadow.
Now click on this link and find the graph that shows the high and low temperatures. Put in today’s date and then at the right click on one year.
Journal Entry: Observe the pattern of the change in temperature through the time period shown. Write a 3 sentence paragraph (using correct format) explaining your observation.
