Year 4 had great fun, getting messy and exploring the human digestive system. We created a practical experiment to show how food travels through the digestive system. A plastic bag represented the stomach where we had placed some crackers, banana and orange juice. After squishing it all together we then passed it through the leg of a pair of tights to represent the intestine. Finally, any solid waste was pushed through two cups to represent the action of going to the toilet! The children's expressions show how much fun we actually had (even if it was a little bit gross!).
