As an educator, I want students to see how science relates to them in the real-world. This document gives student a list of activities they can do outside of school each quarter. They are required to do something up to 2 points each quarter that is 10% of their grade. They can do this with classmates, friends, or family, and have to complete the assignment that goes with it.
I put available free dates so students don't have to pay (change as needed), and provide online assignments if they are really against going out and doing something related to the class. This can be applied to all science content areas, but the assignments would need to change to make it applicable to your class.
