EVALUATE: A science fair group presents a project claiming that a roller coaster has equal amounts of potential and kinetic energy at the top of the first hill. Using your knowledge of energy transformations, evaluate the accuracy of their claim. Do you agree or disagree? Support your answer with scientific reasoning and include an explanation of how energy changes as the roller coaster moves along the track.

EVALIATE: During a class experiment, two students are arguing about a toy car rolling down a ramp. One student says, “The car speeds up because it's gaining energy.” The other student says, “No, it already had energy at the top, and that energy is just changing form.” Evaluate both students’ statements. Who do you agree with more, and why? Use scientific reasoning about potential and kinetic energy to support your answer.
