Protect your child’s health by using this experiment to demonstrate how germs are passed.
Demontrate to your child the scientific truth behind the saying “One rotten apple spoils the whole barrel.” This experiment will show why so many people can get sick at the same time.
Explain to your child that the toothpick transferred the bacteria (one-celled organisms that produce substances that build up or break down organic materials) from the sick apple to the healthy apple. This is what happens when someone who is sick passes on their germs to other people, by touching or breathing. This is why you should wash your hands before eating and cover your mouth when you cough.
