Journal Entry - Take out your science journal and answer the following question(s) (use drawings as appropriate):

How does the appearance of the night sky change with the seasons?

Materials:

  • Four signs, one for each season
  • Constellations placed in their appropriate season

Procedure:

  1. Label each wall with the season sign.

  4. Your arms represent the horizon. You can see only what is within your horizon.
  5. Observe which constellations you can see.
  6. Move counterclockwise (this simulates the earth’s revolution) 1/8 of the way around the room and observe which constellations you can see now.
  7. Repeat Step 6 until you are back to their original position.
