Appearances Can Be Deceiving

 
Journal Entry - Take out your science journal and answer the following question(s) (use drawings as appropriate):
Are all the stars in a constellation the same distance from the earth?
 

Materials:

  • Four to eight stars that are 3 or 4 inches wide
  • String
  • Tape (or another method to secure stars to ceiling)
 

Procedures:

  1. Attach stars to string and hang from ceiling within a 2 foot by 2 foot area. Do not hang them in a straight row.
  2. Observe the stars by standing 50 feet away.
  3. Move closer to the stars and observe the stars again.
  4. How did the distance of the individual stars appear to change?
 
Use the picture below to graph each individual star in the Orion constellation. Each star is marked with its distance from Earth in Light Years (l.y.) Create the graph in your science journal.
 
 

 

Conclusion:

From this, what can you conclude about the distances of individual stars in a constellation?

Extension:

Make a T-graph comparing and contrasting the stars in a constellation.
