Germ Science Activity

Germs, and fever, and sickness, OH MY! During cold and flu season, it's important to teach children about handwashing and proper sanitation practices. This intriguing activity is incredibly effective in illustrating how easily germs are transmitted and how perfectly hand washing can prevent further spreading.

Why It Is Important to Teach Children About Germs

Teaching children about germs is important to keep everyone as healthy and safe as possible. When children understand that germs and the spread of germs are what make people sick, we can then educate them on how to safeguard themselves and protect their environment.

How to Teach Children About Germs

Explaining that germs are so tiny that we can't see them is an abstract concept. Incorporating the germ science activity into a lesson about germs will serve as an illustration of how they are spread. You can emphasize this concept by using a microscope or magnifying glass to enlarge materials children may not normally see. Be sure to encourage children to cough and sneeze into their elbow to block germs from circulating in the air.
