Charlie placed a pencil in a glass of water as shown in the picture. Why does the pencil appear broken?

• The bottom part of the pencil refracts light.

• The light reflects from the surface of the water.

• The curved surface of the glass absorbs the light.

Alana and Juan used a meter stick to mark heights of 2 m, 4 m, and 6 m above the ground. Alana dropped a ball from each height. They repeated this several times to increase the reliability of the results. Juan measured how high the balls bounced each time and recorded the information. Predict which ball bounced the highest. Explain by describing the energy of the balls.
