In this health activity (on page 3 of the PDF), learners will learn about the body‘s defenses against invasion from tiny particles. They will make their own "snot" and see firsthand how effective it is at preventing particles from entering the body. Although this was created as a pre-visit activity for a workshop about the human body, it also makes an excellent stand alone activity! This is a crowd favorite at our science center.
