Bacteriology Science Fair Project

Bacteria-Busting Chopping Boards

Bacteria-Busting Chopping Boards | Science Fair Projects | STEM Projects
Are you curious about how Microban chopping boards can help reduce bacteria growth? In this science project, you'll compare the number of bacteria colonies on plastic and Microban chopping boards to see which one has fewer bacteria.


The hypothesis is that Microban chopping boards have less bacteria growing on their surfaces.

Method & Materials

You will make scratches on the surfaces of 3 plastic and 3 Microban chopping boards, cut up pieces of chicken on them, and then rub a swab on the surface of the chopping boards and roll it over the surface of the Petri dishes.
You will need 6 agar Petri dishes, 6 disinfected swabs, 1 bottle of disinfected water, 3 plastic chopping boards, 3 Microban polymer chopping boards, 1 knife, 6 pieces of chicken, tap water, a piece of soap, and 1 marker pen.


The results showed that the samples taken from the Microban polymer chopping board had a smaller number of bacteria colonies. This proves that the hypothesis is true.

Why do this project?

This science project is interesting because it shows how Microban polymers can help reduce bacteria growth on surfaces.

Also Consider

Experiment variations to consider include repeating the science project to compare bacteria growth between Microban based products and anti-microbial sprays, or repeating the science project with other Microban based products like a computer keyboard or mouse.
