Even though we cannot see it with just our eyes, very tiny bacteria and viruses are all over the Earth. Some bacteria even live inside our bodies! Some bacteria make us sick, while other bacteria are actually helpful to us. Luckily, both our bodies and scientists have developed ways to protect us from the bacteria that makes us sick.
The following activities will help you discover how bacteria grow, how we fight harmful bacteria, and even what bacteria looks like. We hope you enjoy these activities and do them together as a family.
