Hands-on Activity

Clean Class

Fun Forces
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.

Activity Difficulty Rating: 1 Each hands-on science activity has been ranked based on difficulty of set up and how difficult they are to perform. The rating scale is from 1 to 5, with 1 being the easiest and 5 being the most complicated.
