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 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.

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.
