Germ Hotspots | Science Fair Projects | STEM Projects
Are you ready to explore the world of germs? In this science project, you will investigate the places with the highest amount of germs. You will use petri dishes and swabs to collect samples from different locations and observe the number of bacteria colonies that grow.

Hypothesis

The hypothesis is that continuously damp places such as the button/handle of a water cooler will have the highest amount of germs.

Method & Materials

You will use 5 agar petri dishes, 5 disinfected swabs, 1 bottle of disinfected water, and 1 marker pen. You will rub the swab on different surfaces and roll it over the agar in the petri dishes.
You will need 5 agar petri dishes, 5 disinfected swabs, 1 bottle of disinfected water, and 1 marker pen.

Results

The results showed that petri dish C (water cooler) and E (door knob) had the largest bacterial growth. This proves that the hypothesis that continuously damp places have the highest amount of germs is true.

Why do this project?

This science project is interesting and unique because it allows us to explore the world of germs and understand how they can affect our lives.

Also Consider

Experiment variations to consider include testing for bacteria at locations like restaurants, schools and other public areas, and repeating the experiment using personal items like mobile phones, wallets, watches, etc.
