Broad Question
Does the material of a hockey stick affect the speed of a hockey puck being shot?

Specific Question
Which will affect the shot speed of a puck being shot more, a graphite or a wood stick?

Independent Variable:
Stick Material

Dependent Variable:
Shot Speed (mph) http://t0.gstatic.com/images?q=tbn:ANd9GcSyoMNnHInJ-I6vTDIFHWTkeBauz6Dk2ApkQZE7PZS5ShQmuNtF9w

Variables That Need To Be Controlled:

 * Which person is shooting
 * The amount of flex put down on the stick
 * Same blade/ curve on each stick
 * Same size stick

Hypothesis
I hypothesize that a graphite hockey stick will affect the shot speed of a puck being shot more than a wood stick.

Experimental Design:
 For the Science Fair I am testing “Which will affect the shot speed of a hockey puck being shot more a graphite or a wood stick?” My experiment will be conducted at an ice arena (The Ham Arena or Notre Dame Arena). In my experiment I will have one person shooting the puck on goal and one person clocking the speed with a radar gun behind he net. For shot speed I will be doing twenty trials to get a reliable conclusion that will show strong evidence on which stick material is better. When conducting my experiment I will be ice. In order to make it easier, I will be recording my data on a printed out data table. To show i did the test, I will be taking pictures to be uploaded and printed out, as well as a video.

Materials List:

 * Wooden one piece hockey stick
 * Graphite one piece hockey stick
 * Ice to skate on (a.k.a an arena)
 * Puck
 * Skates
 * Hockey Gloves
 * Helmet
 * Net
 * Radar Gun

Detailed Procedure:

 * 1) Grab hockey gear. (Helmet, Hockey gloves, Wooden Stick and Graphite Stick, Puck)
 * 2) Go to the ice rink
 * 3) Put on gear
 * 4) Go on the ice
 * 5) Set up the net
 * 6) Set up the radar gun behind the net
 * 7) <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">Skate and straddle a line across the tops of the face-off circles
 * 8) <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">When center in the line, shoot the puck on the net
 * 9) <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">Record the shot speed
 * 10) <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;"><span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">Repeat steps 7 through 9 until all data needed is recorded (I will shot each stick twenty times)

Background Research
<span style="background-color: transparent; color: #000000; font-family: Times New Roman; font-size: 16px; text-decoration: none; vertical-align: baseline;">1.Hockey sticks have a long slender shaft, at the bottom a flat surface called the blade is used to move the puck. The flexibility determines how much energy the stick absorbs and transfers to the puck when being shot. The energy is not directly transferred to the puck. The sick bends and keeps (stores) the energy before transferring to the puck. Today sticks are now designed to flex at certain parts of the stick to give off massive speeds to the puck, when it is being shot.

<span style="background-color: transparent; color: #000000; font-family: Times New Roman; font-size: 16px; text-decoration: none; vertical-align: baseline;">2.Flexing your stick while shooting turns the hockey stick into a spring storing energy. When the spring releases ( when the hockey stick snaps back straight to the original form) the energy is released and accelerates the puck. When shooting and the stick is to stiff for the player shooting the puck you will not get the extra acceleration push on the puck that you would get while flexing (bending) the stick.

<span style="background-color: transparent; color: #000000; font-family: Times New Roman; font-size: 16px; text-decoration: none; vertical-align: baseline;">3.The flex of a hockey stick is crucial. The right mount of flex could up your flex that much more in every shot you take. On the other hand to much or to little flex could down your shot every time you shoot. The stronger the stick and harder to bend, (like wooden sticks) the more muscle it takes to flex the stick. The flimsier the stick and easier to bend (like graphite sticks) the less muscle it takes to flex the stick 4. <span style="background-color: transparent; color: #000000; font-family: Times New Roman; font-size: 16px; text-decoration: none; vertical-align: baseline;">The flex of a hockey stick is the measure of stiffness in the sticks shaft. When pushing down with lots of power the shaft will gain more energy and realise the puck with a fast spring like motion sending it at enormous speeds. Depending on your weight and age group the amount of flex that you should have on your stick and the stick material is differd.
