The Best Kind of Arrow for Hunting

By: Dominic Strivens

Purpose Statement

The purpose of this experiment was to see which kind of arrow shoots the straightest. I became interested in this experiment because I want to get better at hunting with arrows. The information gained from this experiment will help others by telling them which arrow shoots the straightest.

Research

Before you release an arrow from a bow, it is straight, but when you let it go, it bends back and forth. A bow is usually made in a shape of a flexible arch which ends are joined by a string. When the string is drawn back together with an arrow, the ends of the bow are flexed. When the string is release, ends of a bow straighten. They pull the string with them and propel the arrow forward. The main parts of a bow are a pair of curved elastic limbs (upper limb and lower limb) that are held together by a riser.


Elastic limbs have at their ends nocks, which are used to attach the bowstring to the limbs. The riser is further divided into the grip (which an archer uses to hold a bow), arrow rest, and the bow window. The bow window is a part of the riser above the grip. It contains the arrow rest which is a small ledge on which the arrow rests before it is propelled. Bows can be made out of wood or be composite bows, made from different materials which are specialized for the different functions of a bow

Hypothesis

My hypothesis is the carbon arrow will shot the straightest. I base my hypothesis on the carbon arrows are lighter.

Materials

1 bow

3 different arrow types

1 target

1 range finder


IV: Arrows

DV: Shot straightness

CV: Shooting starting point

CV: target

Procedures

1. Get the arrows and bow.

2. Mark and stand at a shooting starting point.

3. Shoot one kind of arrow at the target

4. Use the range finder to determine the distance away from the center of the target the arrow landed.

5. Repeat steps 3-4 two more times.

6. Repeat 3-5 with each of the different types of arrows.

Results:

The original purpose of this experiment was to see the kind of arrow that shoots the straightest. The results of the experiment were the carbon arrow hit the middle 20 times, and it missed 15; the wood arrow hit the target 19 times and missed the middle 16 times; the aluminum arrow hit the target 11 times and missed 24 times.

Conclusion:

My hypothesis was the carbon arrow will shoot the straightest. The results indicate my hypothesis should be considered right because the carbon arrow hit the middle the most. Based on the results of this experiment, you should use a carbon arrow when hunting animals. If I were to conduct this science fair project again, I would use the same kind of arrows and different kinds of bows.
