Germs and the Body

Germs and the Body


If germs are able to get inside the body, they may keep it from working properly.This activity explores germs, where they exist, and how they can affect the body.


Where Bacteria Are Found

Discover where bacteria can be found by exploring Bacteria in the Cafeteria. When you get to the game, click the purple Play button. You'll go to a screen that shows a cafeteria and there are a bunch of white stars with blue outlines. Click on each star to answer a question about bacteria. Find all 12 stars in the cafeteria to solve the puzzle.

Answer these questions on your Germs and the Body student sheet once you've finished the game:

  • Where can bacteria be found? 
  • How does bacteria help the human body? 
  • How can bacteria infect the body and interfere with normal body functions?
  • How do you think too much bacteria (or other substances) in the soil, air, or water could affect humans? Explain.
  • Are there other ways that viruses or bacteria infect (get into) the body?
