In this activity, kids will experiment with different mixtures to replicate how ruminant digestion works.
The digestive tract of ruminant animals, such as cows, sheep, and goats, differs from that of other animals because instead of the single-chamber stomach that humans have, it has four. These chambers help to ferment and break down food, and eventually absorb nutrients. Pop rocks and soda aren’t the healthiest of snacks, but in this activity you are going to use them to replicate the digestive system of a cow.
