During the past two weeks, the Ag Science class, taught by Mrs. Standley, was given the challenge of building and designing small, Co2 powered cars, also known as dragsters. The dragsters were put to the test in a race against each other in a bracket-style competition.The project begins with each student deciding the shape and size of their dragsters. Their intent when building their dragster is to be faster than their classmates.
The dragsters themselves are made of wood while the wheels are made of plastic. Each dragster is designed to be aerodynamic and lightweight, as each car has the same amount of force propelling it forward.
For the actual competition two 60 feet strings are laid on the ground in the gym and each car has a small loop on the bottom of the car for the string to go through. This string helps the car to stay moving in a straight line and stops the cars from flying in any direction it deems fit. Small Co2 canisters are put in the backside of the cars and when ready, the valve to the canister is opened. The escaping gas pushes the car forward at high speeds. Two dragsters race at once and to make sure each valve is released at the same time and placed in front of a starting bock where a leveler controls the opening of the valves to ensure proper timing.
Out of the ten dragsters that were built by the Ag Science class, Laura Minette's was the winner. Despite being smaller and oddly shaped, Laura's car prevailed. Some might say the race was a perfect example of the saying, don't judge a book by its cover.
