- Grade 8
For our experiment, we collected bacteria from different surfaces, and observed the amount of bacteria, along with the type, shape, and form.
We are Mia Resnick and Kemi Komolafe. We are in 8th grade and are researching bacteria found on masks and other ‘often-touched surfaces’ such as doorknobs and tables. Because we are in a global pandemic, we wear masks and take other precautions to prevent the spread of infection. Therefore, we were interested in seeing how much bacteria is on certain surfaces and how easily things spread. Our goal is to observe the amount and types of bacteria that we find on these surfaces. We had seen previous videos on social media doing similar experiments, and we thought it would be interesting to try it ourselves. This experiment is an observational study, we do not measure anything, just observe what we notice.
To execute this experiment, first we used agar plates or petri dishes to incubate and collect bacteria on. Using sterile swabs, we swabbed and collected bacteria from surfaces. We then let the dishes incubate
for the recommended time, and then started our observations. We looked at amount, type, and size
of the bacteria hoping to come to the conclusion of which surfaces hold the most bacteria, and
what type it is.
