Ping Pong/Marble (Big, small), Golf Ball, Styrofoam Ball, Pink Plastic Ball

Reflection:

My partner and I had tested the reaction of the manipulated variables hit against the wall back and forth, bouncing. We marked as the manipulated variables hit the wall and bounced, also we had discovered that majorities of the manipulated variable hit against the wall forms a triangle shape. The reason behind this was the angle thrown; by looking at the graph or the test, we can see that some had bounced against the wall and some curved before hitting the wall.

Data:

Ping Pong: Well hit, bounced as well, formed triangle

Marble (Small, Large): Small has been curved; however large one had formed a triangle

Golf Ball: Formed a triangle

Pink Plastic Ball: Not much to probe, made an attempt but no result

Styrofoam Ball: Due to its lightness, it wasn't able to hit and bounce back easily.

In conclusion, I observed that angles and the size of the manipulated variable changed the test data. As you can see above the conclusion, the data suggests that large size variables had formed a triangle however the small variables haven't. Nevertheless, we are not sure if this test went well since the angle or the speed put in is not always the exact same. I assume that this test went well, and I hope there can be a photo to account for my test explanation.
