In this activity, students will observe different areas of the classroom and make predictions about which areas have
the smallest and largest amount of germs. They will then observe pre-made samples of colonies of microorganisms
from the different locations in the classroom.
Real World Science Topics:
- An exploration of how microorganisms grow
- An exploration of how the cleanliness of an area is related to microorganism growth
Students will gain an understanding of the concept of microorganisms, and will learn that there is a connection
between the cleanliness (or use) of an area and the amount of microorganisms in that area.
