Scenes from a field trip to the Lawrence Hall of Science “Grossology Exhibit” where students explored in hands-on and feet-on activities, giant animatronics, and computer games how the human body fights germs, breaks down food, gets rid of trapped air, removes waste products, and performs other critical functions. “Enter Grossology and discover the anatomy, biology, chemistry and physics of why we sneeze, vomit, belch, and even stink.”
