In this experiment we were trying to find out how light reflects off different objects. The objects we used were a mirror and a bouncy ball. We bounced the bouncy ball off the mirror to see how light reflected of the mirror. We saw that if you threw the ball at an angle it would bounce at the same angle when it comes up. If you dropped the bouncy ball straight down it came straight back up.
Claim. When light comes down at an angle it bounces and continues in the same direction you threw it. Only if light hits a smooth surface. If light hits a rough surface it bounces in many different directions.
Evidence. When we bounced the ball off a smooth surface, the angle we threw the ball was the same angle as the angle after the bounce. When we bounced the ball off a rough surface it went in many different directions. Mrs. Hansen took a piece of crinkled up foil and shined a lazar light on the foil, it reflected in many different directions. So, no one could see it. She shined the lazar on a smooth piece of foil and it reflected off and came to the back of the room and everybody could see it. What surprised us the most was that the ball did the same thing as the light.
