The Digestive System
P5 are learning about all the important systems of the human body. Last week we were finding out about the digestive system and we used bananas and crackers to represent the food we eat. We added some water to act as saliva and some orange juice to represent the acid in our stomach. We all enjoyed using our hands to mash up the food like the stomach wall would do in our bodies. Then we transferred the contents of the stomach into the small intestine and watched as the nutrients from the small intestine flowed through the wall of the intestine. When all the moisture had been squeezed out we transferred the remaining food waste into a cup which acted the large intestine and we pushed it out through a small hole, just like going to the toilet. What a messy way to learn about the digestive system!
