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.

Joe’s idea is already a scientific law.
Joe’s idea is not supported by scientific evidence.
Joe’s idea is a good guess that can be tested by experiments.

In 1897, Joseph Thomson discovered that atoms contained electrons. He proposed a change in the atomic theory of that time, and the theory was modified because of his discovery. Since Thomson’s discovery, atomic theory has been further modified. What is the best explanation for why scientific theories are modified?
Theories more than ten years old are usually out of date.
Scientists want to prove that the work of other scientists is wrong.
New evidence that supports a change prompts scientists to modify earlier theories.
So much information is available today that it is harder to focus research and disprove theories.
