How Sneezing Spreads Germs - No A? Walk Away!Guiding Question:
How can sneezing spread germs to food?

Materials:
spray bottle; water; blotter or colorful construction paper

Procedure:

  1. Fill the spray bottle with water. Cut the paper out in the shape of a slice of bread or other food item.
  2. “Sneeze” with the spray bottle aiming at the paper.
  3. Spray the bottle at another piece of paper, but this time from five feet away.
  4. Repeat at varying distances.
  5. Repeat with your hand in front of the spray bottle “nose.”
  6. Repeat once again, but this time “sneeze” into your elbow.

Be sure to record all of your observations.
