The purpose of the experiment is to find out if the 5 second rule is true and if it is safe to eat food off the ground.
You asked a question that many people wonder about, and you tested it in a clear and organized way. You used multiple foods, different times, and repeated trials, which make your experiment stronger. Your results also made sense and showed good reasoning; moist foods like apples picked up more bacteria than dry foods like pretzels. This is a practical project that helps people think about their health and medical safety when it comes to picking up and eating food dropped on the floor.
Excellent project testing the “5-second rule.” I liked how you compared different foods and measured bacteria growth across multiple trials. Your experiment clearly showed that moist foods like apples picked up more bacteria than dry foods like pretzels. The photos of the Petri dishes, data tables and graph made the results easy to understand.
