Ms. Kahn’s science class is studying the concept of natural selection. Charles Darwin used this concept to explain how living things evolve over time. Some students, however, don’t think Darwin’s explanation is enough.

“Even if humans and animals evolved over time, didn’t the universe have to start from somewhere?” says Victor. “From my perspective, we should learn about the intelligent design concept, too. My dad says it should be considered a scientific theory just like Darwin’s,” says Victor.

“What?!” exclaims Kareema. “Intelligent design isn’t scientific at all! My mom says it’s creationism disguised as science. If some intelligent being created and designed all life on Earth, then who or what created that intelligent being? Can you explain that?”

“Hold on, Kareema,” says Ms. Kahn. “We can address your disagreement with Victor by investigating how we decide if something is indeed ‘science.’ Let’s consider some criteria for what makes a theory scientific, and then you and Victor can decide for yourselves.”

Kareema and Victor looked online and found the following list of criteria for judging whether or not a theory is scientific.

Discussion Question:

With a partner, discuss whether or not intelligent design is a scientific theory based on the above criteria. Try to use the focus words (design, creationism, concept, evolve, and perspective).
