This week, Primary 3 have been learning about germs and diseases. We are investigating how germs can spread and grow on different surfaces by conducting an experiment with a potato.
We cut the potato into 4 slices and put the first slice in a plastic bag. This is our control slice to see how a potato would decay normally. We then rubbed the other slices on different surfaces before putting them into bags to see which would result in the most bacteria growing. Our slices were then labelled and placed in a cupboard. We will have to wait until next week to find out the results.
