Theory, Theory, Who's got the theory?
Students analyze 5 separate theories of evolution in order to help them explain the different meanings of theory, how human values influence science, and that the scientific view of the origin of life does not involve supernatural forces.

The Evidence is “Clear”!
Do you think you know better? Become a scientist and prove it. Scholars review the evidence for two different theories of the origins of the universe. They notice the empirical observations as well as the inferences to determine which is...

What’s the Problem with Isotropy?
Some patterns are so small, we can't see them without the help of technology. The same is true for cosmic microwave background radiation. During this activity and discussion, scholars examine both anisotropic and isotropic items and...
