B i g q u e s t i o n

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.


H y p o t h e s i s

Hypothesis

  • I think that you can shoot a hockey puck faster from a shorter distance.


I n t e r e s t i n g f a c t s

Interesting Facts

  • That the puck can go faster when you use a composite stick not a wood stick.

  • When I shot it from the long distance the puck had hit the ground before going into the goal net.

  • The shorter distance didn’t hit the ground before going into the goal net.

  • That the harder puck went slower then the softer puck.

  • That you can shoot a puck on wood floor.


M a t e r i a l s

Materials

  • You will need a tape measure, a hockey puck, a hockey stick, a goal net, a helper, and a stopwatch.


S t e p b y s t e p i n s t r u c t i o n s

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.


V a r i a b l e s

Variables

  • It’s a faster shot from the shorter distance (12ft.) then the longer distance (24ft.).


O b s e r v a t i o n s

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.


D a t a

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.


A n a l y s i s o f d a t a

Analysis of data

  • The hot temperature will allow the puck to go faster.

  • The colder weather will make it go slower.


C o n c l u s i o n

Conclusion

  • My hypothesis was correct that the shorter distance went faster than the longer distance.
