What a merry time we had during our hands-on digestive system investigation! All the 3/4 classes got stuck in to learning how our body processes food. We learnt how our body extracts nutrients and how it gets rid of the bits we don’t use. Our investigations included cream crackers and bananas as food, water as saliva, orange juice as stomach acid, a stocking as our small intestine, a plastic bag for the stomach and a cup for our large intestine.
