Extra Credit Opportunity There are 4 planetarium shows that are 8th grade age appropriate. You may attend any or all of the shows. I’ll give 15 point for each separate show you attend. You may not get points for attending the same show twice. You must bring me a ticket signed by a planetarium employee (or volunteer) or a program (if they have them). You must also write a brief summary of what you learned.60 points are possible.
