Blasting Blades

Overview

Objectives/Goals Experiments were performed to determine which hockey stick blade length would produce the most speed. The focus was on the speed that was being produced by the different length blades. The adult length blade was thought to have been to produce the most speed. Methods/Materials To test the different blade lengths, a blade swinging machine had to be built. Then the junior length blade had to be swung forty times. Next, the intermediate length blade had to be swung forty times. Finally the adult length blade had to be swung forty times. After all the data was recorded, it was converted from miles per hour to kilometers per hour. Results The results showed that the junior length blade produced the most speed with an average of 24.74375. The junior length blade is the shortest out of all three. The adult length blade, which is the longest length blade, did the worst with an average of 15.2045. The intermediate length blade was thought to be right in the middle for length and speed and it was. Conclusions/Discussion In conclusion, the junior length blade did the best. The hypothesis, which was that the adult length blade was thought to produce the most speed, was proven wrong. The adult length blade did not produce the most speed.
