Big Question
Can you shoot a hockey puck faster from farther away or closer.
I want to do this to see if I need to improve my shoot or not.
Hypothesis
I think that you can shoot a hockey puck faster from a shorter distance.
Interesting Factso That the puck can go faster when you use a
composite stick not a wood stick.o When I shot it from the long distance the puck had
hit the ground before going into the goal net.o The shorter distance didn’t hit the ground before
going into the goal net.o That the harder puck went slower then the softer
puck.o That you can shoot a puck on wood floor.
Materials
You will need a tape measure, a hockey puck, a hockey stick, a goal net, a helper, and a stopwatch.
Step by Step instructions
1. gather up all of the materials you need.2. have the helper on one of the sides of the
goal net.3.Start the stop watch when the hockey stick
hits the puck.4. once it goes past the line stop the clock.5. Do the same thing over again except from a
different distance.
Variables
It’s a faster shot from the shorter distance (12ft.) then the longer distance (24ft.).
Observations
1. A wood floor is okay to hit a hockey puck on.
2. That shorter distances will travel faster.3. When the puck is in colder weather it goes
slower.4.Goes faster in warmer weather.
Data
• When I shot the puck from 12ft. it was clocked at 00:00:00.24.
• When I shot the puck from 24ft.it was clocked at 00:00:00.36.
Analysis of data
The hot temperature will allow the puck to go faster.
The colder weather will make it go slower.
Conclusion
• My hypothesis was correct that the shorter distance went faster than the longer distance.
