Joe tells Gabby his theory about why sea turtles nest on the beach instead of in the ocean. He says, “The turtle eggs would sink to the bottom of the ocean, and the baby turtle would drown. I know this because my uncle is a fisherman, and he told me this information. Gabby tells Joe that his theory is not scientific. Why does Joe’s idea not meet the requirements to be a scientific theory?

Joe’s idea is not supported by scientific evidence.

a)

Theories more than ten years old are usually out of date.

b)

Scientists want to prove that the work of other scientists is wrong.
