Hot Shot or Ice Cold?

In this project, I launched hockey pucks at different temperatures down an ice rink surface to determine whether warmer or cooler pucks travel further. I did this in an attempt to determine what the optimal temperature for a hockey puck to travel furthest down an ice surface is. I discovered that the National Hockey League keeps all of their game pucks at -10 degrees Celsius and wanted to see if that was allowing the pucks to travel at their highest potential distance at that temperature. When conducting my experiment, in order to keep the speed of the hockey pucks constant, I built a wooden puck slinging apparatus. To monitor the temperature of the hockey pucks between tests I used a Raytek laser temperature reader. I did this to ensure that the temperature of the puck did not change significantly between the various tests. After completing my experiment, I found that as the temperature of the hockey pucks increased the distance it traveled was further. I hypothesized the affect would be opposite to this because I thought as the temperature of the puck increased, it would cause pooling and increase the resistance. However, the pooling the increased temperature cause was so minor, it acted as a thin surface for the puck to glide upon and allowed it to travel further.
