Joe tells Mai 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 turtles would drown.” Joe says his uncle is a fisherman, who told Joe this information. Mai tells Joe that his theory is not scientific. Which explanation supports Mai’s evaluation of Joe’s theory?

• 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. 

• Joe’s idea accurately explains why sea turtles nest on the beach. 

A scientific theory...

• is based on lots of evidence

• is not valid

• is not reliable

• has not been tested many times

Mai tells Jaz his theory about what sea turtles nest on the beach instead of in the ocean. She says, “The turtle eggs would sink to the bottom of the ocean, and the baby turtle would drown.” Mai says her uncle, a fisherman, told Mai this information. Jaz tells Mai that her theory is not scientific. Why does Mai’s idea not meet the requirement to be a scientific theory?

• Mai’s idea is already a scientific law

• Mai’s idea is not supported by scientific evidence.

• Mai’s idea is a good guess that can be tested by experiments

• Mai and her uncle are not scientists

Scientific theories are usually

• based on opinions and feelings.

• supported by evidence and widely accepted by the community.

• unable to change as new data or technology emerges.

• claims posed by individuals.
