How can we stop germs in their tracks?

GERMS. They lurk in every classroom. Each year, students miss an estimated 164 MILLION school days due to illness. In this project, students will fight back against these microscopic monsters with this public-service project designed to make your school—and the world—a safer and healthier place. They will collect germs from common surfaces such as desks, laptops, and more. Then they’ll test the effectiveness of disinfectants in fighting germs. Finally, they’ll create a public service announcement for their school!

Imagine if kids could keep themselves and their families healthier by developing smart habits to protect against germs. What a great way to build healthy routines to last a lifetime!

‘Hello! My name is Tammy Myers and I’ve been a teacher for Nixa Public Schools since 2000. I dreamed of being a teacher since I was a second grader, and after all these years, I’m just as passionate about it! I love getting to come to school everyday and learning with my fourth graders. I graduated from Missouri State University with a bachelor’s degree in Elementary Education and from Lindenwood University with a master’s degree. When I’m not at school, I enjoy spending my free time with my family and friends, reading, shopping, and serving at my church. On Saturdays you can usually find me at Busiek State Park riding my horse, Stormy.
