   What goes in one end and must come out the other end, or so the digestive system goes.

   In the Murray Park summer school class “Grossology,” third- through fifth-grade students learned about the digestive system by making “poop.”

   The kids mashed up bread, oats and half of a banana in a bag, which represented the breakdown of food in a person’s mouth when they chew.

   They then added a little bit of vinegar to represent stomach acids, which further breaks down food.

   However, they didn’t realize yet they were making poop. When teacher Terry Boe announced the purpose of the project, kids’ faces scrunched up with shock and then disgust.

   Afterwards, kids could dump their messy, goopy mixture onto a paper towel and roll it, to make a replica. The paper towel acted as the body’s intestines to draw out the liquid or nutrients.
