Abstract

   

I first thought about creating an experiment involving parachutes when I was in fifth grade, and now that I am in tenth grade I finally fulfilled that desire. Some things that one must include when dealing with parachutes are: the types of material for the parachute, the weight of the object, the design of the parachute, gravity, and the wind. The main question I had in regards to this experiment was, “What is the most effective design and material for a parachute in terms of speed?” And my hypothesis was that if it did affect its performance, then the nylon material and the hemisphere design would perform the best in terms of speed of descent. When creating a parachute, one must first design the size of each of the gores of the parachute. Secondly, with scissors cut out each of the gores until you have six gores, then, using thread and a needle, sew each gore together to create the parachute. Next, punch two holes with a scissors or a knife on each side of each gore. Finally, place the string through the holes and tape all twelve pieces of string to the plastic bottle. When finished, complete the procedures again for a second time for the other parachute. Now, it is time to test the parachutes. First, find a tall place to drop the parachutes from. Then drop both parachutes and the plastic bottle one at a time, and simultaneously, using a stopwatch, time the amount of time it takes the parachute to hit the ground. Repeat the process five times. So after experimenting, my hypothesis was supported by the data; the nylon parachute and the hemisphere design performed the best followed by the cotton parachute. A future project related to this topic would be creating the best mechanism that would open the parachute from a backpack.
