I saw this on a Bright Horizon email and thought that it was a fun way to help kids understand the importance of hand washing.
Flaked spices such as dill, parsley, and cilantro
Plates or bowls
Fill bowl or plate with water and have your child sprinkle flaked spices on the surface of their water. Tell your child to imagine the flakes are like the germs on their hands. They can then dip a Q-tip into the soap and touch the surface of their water. What happened to our pretend germs? Why do you think the germs moved away? Explain that soap does the same thing to real germs when we wash our hands.
