Bacterium in Novae Hamptoniensis
Germs and bacteria are everywhere, and in today’s world we don’t even seem to notice all the shared surfaces we touch without washing our hands. Most bacterium are harmless and they keep us healthy, by digesting food and protecting us from other harmful germs otherwise known as pathogens through vaccines and medications. Germs grow the best at high temperatures, in dark areas, with wet conditions. Madison Schumacher conducted a lab in her IB Biology class, investigating if location on NHS campus affects the number of bacteria living on the surfaces.
She swabbed over 50 surfaces and allowed the bacteria to grow in petri dishes with an agar mixture for 72 hours. She concluded that the bathroom sink handles, panini maker handles, ARC computer keyboards, and the water fountain buttons were some of the dirtiest surfaces on campus. So be sure to wash your hands and keep all your surfaces clean and remember to stay healthy!
