Tyler and his sister went to the beach. Tyler sat in the sun, and his sister sat in the shade. Infer what happened to each person's skin temperature. Explain.
Tyler's skin temperature increased, but his sister's did not because she was in the shade. Tyler received more heat energy from sunlight.

Carly is sitting at the top of the slide. What type of energy does she have? Is it possible for her to change her energy? If she changes her energy, what type of energy will it become? Explain your answers.
She has potential energy because she is just sitting at the top of the slide. Potential energy is the energy of position. If she slides down, she can change her energy from potential to kinetic. Kinetic energy is the energy of motion.
