My project is about testing different disinfectants to see which one kills the most bacteria. I chose this project because cutting boards can have a lot of germs/bacteria and I wanted to know what works best to keep people safe/healthy. My results showed that bleach had the least amount of bacteria. It helps people understand which disinfectant cleans the best.
Your project followed a very strict scientific method with clear variables and organized measurements. Your ‘Real-World Connection’ to winter gardening was very practical.
Great scientific work, and inputting real‑world connection shows great thinking.
Good job
It is clear that you worked very hard on this experiment over three full weeks! Your organization of the different light groups and your detailed measurements each week show excellent scientific habits. good job!
