We placed the biscuits and banana inside the ziplock bag, this represented eating. Added tablespoon of water-the saliva. We then crunched the food up inside the bag-chewing. Then mimicked the action of the stomach by adding acid-the orange juice. We discussed how the mixture moving over to the small intestine.
We the squeezed the food down to the bottom so it imitated the small intestine becoming the large intestine, or colon. We then squeezed the mixture and extracted as much water as possible over the bucket. What we were left with was the poo!
