This week in Science we have been learning all about the digestive system.

We carried out a practical investigation to show the journey of food through the human body. We started by tearing, breaking and grinding food by teeth (mechanical digestion). The food was then mixed with saliva (water) and travelled down the oesophagus into the stomach. Once in the stomach it was mixed with stomach acid (chemical digestion).  After breaking down in the stomach the food travelled to the small intestine. Did you know that an adult small intestine is over 6 metres long? The nutrients from the food were then absorbed back into the body while the rst of the food travelled through the large intestine ready to come out of the body.


The children had great fun with this very messy investigation!
