Science Project idea:
2. Potato Germ Prints. To show the number of "germs" on a finger, take a clean slice of potato and make a thumb print on it. Do the same with another slice after you washed your hands. Place these slices in clean containers and observe the growth of "germs". Do some research on other microorganism growth materials and how to conduct this type of an experiment.
