Abstract or Description

I hope to discover which disinfectant works best at killing common household germs so I can use that disinfectant to kill the most bacteria around my house. I picked this topic because I want cleaning products that work well and have good results to kill germs because I get sick a lot.

My hypothesis is that all of the disinfectants will kill roughly the same amount of bacteria. I used several petri dishes, sterile cotton swabs, sterile water, Clorox wipes, generic disinfecting wipes, and a homemade disinfectant spray. I also used tape and gloves and a marker. I used an incubator to speed up the growing process of the bacteria.

My hypothesis was rejected because my data shows that all of the disinfects cleaned differently on the different surfaces.
