Alyssa has taught her pet rat to run a maze. She thinks that the rat will go faster if she puts its favorite treat at the end. She has the rat run the maze ten times with the favorite treat and ten times with a regular food pellet. She uses a stopwatch to measure how long it takes for the rat to get to the reward.

Tamar is talking about evolution with a friend. The friend says, “It’s just a theory, so I don’t believe it. When they prove it and it becomes the law of evolution, then maybe I’ll change my mind.” Which of these possible replies best describes scientific principles or the work of scientists?
Scientific theories do not become scientific laws; they are explanations for natural phenomena based on evidence.
Science always finds the right answer; the answers that scientists and researchers discover never change.
He should be wary of science because it is based on research and evidence, not bias and opinion.
Scientists take each other at their word regarding experimental results, and the public should, too
