Why would your pencil look like it was in two pieces if you placed it in a clear cup of water? (Answer in 2 or 3 complete sentences)
Your pencil looks different when it goes from air to water because light bends when it goes from one material to another. This happens because the light changes speed as it goes from air to water. Light can’t bend around objects, so it changes directions at an angle as it goes from one material to another.
