"The purpose of this experiment was to determine which antiseptic substance could deplete bacteria found in a sink most efficiently. My question intended for this project was, What plant or medication can reduce the most bacteria in a petri dish? My hypothesis was, If medication is added to a petri dish with bacteria, then it would decrease more bacteria than if plants were added. The procedure of this project was to grow bacteria for seven days in a controlled environment, count the number of bacteria using the quartering method, add the antiseptics, wait 2 more days, count the number again, and record the results. The results of this experiment were that Azithromycin and Cephalexin decreased more bacteria than ginger and aloe. My hypothesis was therefore correct. "
