Year 4 Science

To finish off our learning about the Digestive System in Science, Year 4 made Poo! We crushed up bananas and added some coffee in the mouth section then squeezed this through a pair of tights which were acting as the oesophagus. After that we squeezed the contents out in to a sandwich bag (the stomach) and added vinegar (gastric acid). Following this, the contents were squeezed through another pair of tights acting as the small and large intestine, before they were eventually cut at the end and the contents were pushed out of the end of the tights resembling poo coming out of the anus. It was disgusting but a lot of fun!
