Today, we observed the potatoes which were rubbed on different surfaces last week to find out how bacteria grows. The bacteria grew the most on the potato which was rubbed on the toilet as there are lot of germs there. Whereas, the bacteria grew the least on the potato which was rubbed on the I-pad because we are constantly sanitising our hands in the school. Super observations 2 White.
