Spreading Germs

Suggested Grades



Students will observe and learn about how and how quickly germs spread from person to person.


  • cooked rice
  • zip-loc bag


  • Pour rice into a zip-loc bag.
  • Ask students to stand in a circle.
  • Begin by putting your hand in the rice and getting a lot of rice sticking to your hand then shake hands with a child beside you. That child shakes hands with the person next to them and so on and so on.
  • The rice should stick to all the hands and works the same way germs do when people shake each other’s hands.
