We had an amazing time growing microorganism cultures on agar plates at Hazen High School. In pairs, we chose hypotheses and tested them out. We let the plates culture over the weekend, and caught up over a Zoom call the next week. We uploaded our results, along with our hypotheses and observations, to an online platform. Then we voted on peers’ work for extra credit. The top-3 hypotheses from each period were:

Period 2:
– “We predicted that the men’s bathroom would have more microbes and bacteria than the women’s bathroom”
– “Our hypothesis was Shoe number #1 would grow more bacteria than shoe #2 because they were worn more.”
– “The Janitors cart is more dirty than the main hallway floor.”

Period 3:
– “I predict that the main staircase will have more microbes because it is used more often.”
– “We tested how effective water really is. We predicted that the unwashed hand would have more microbes than the washed hands.”
– “The eyewash station that is located in the front will grow less bacteria because it is used more often”
