2 Red Investigates….

Last week, we rubbed small chunks of potato in a variety of surfaces and left them in a bag to see what happens to them over time. Today, 2 Red continued with our investigations. The potatoes have been left for a week, we used our observations to find which surface has the most germs.

Why do you think the carpet surface had the most bacteria?

Which other surface could we have used?

Where in the school do you think would have the most bacteria? Where would be the cleanest?
