The Case of the Loaded Gun

Purpose I play paintball just about every weekend with my friend John. He always wins and I believe that it is because he has a better paintball gun. I want to even things up and was wondering if the angle of projection matters. I play paintball just about every weekend with my friend John. He always wins and I believe that it is because he has a better paintball gun. I want to even things up and was wondering if the angle of projection matters.

Question Which angle of projection (75, 60, 45) will send the potato the farthest? Which angle of projection (75, 60, 45) will send the potato the farthest?

Hypothesis I believe that the ___ angle will send the potato the farthest because…. I believe that the ___ angle will send the potato the farthest because….

Materials Potato gun Potato gun Tape ball Tape ball Air compressor Air compressor Plunger Plunger Meter stick Meter stick

Procedure Put tape ball in potato gun and stuff with the plunger Put tape ball in potato gun and stuff with the plunger Close the launch valve and fill the potato gun with air (40 psi) Close the launch valve and fill the potato gun with air (40 psi) Assemble the gun Assemble the gun Aim the potato gun at the desired angle (45, 60, or 75) and turn valve to launch Aim the potato gun at the desired angle (45, 60, or 75) and turn valve to launch Measure the flight distance of the tape ball in meters Measure the flight distance of the tape ball in meters

Data and results Table Table Graph Graph Explain the graph (AKA – statements) Explain the graph (AKA – statements) 45 degrees – (3 rd place) 175 meters 60 degrees – (2 nd place) 200 meters 75 degrees – (1 st place) 225 meters

Variables Independent – angle of launch Independent – angle of launch Dependent – the change will be measured in the distance (meters) that the tape ball traveled in the air Dependent – the change will be measured in the distance (meters) that the tape ball traveled in the air
