Digestion in the Bag

18th September 2020

Year 4 students are starting the new academic year by learning all about the digestion system in their Science lessons.

They used a zip-lock bag to represent the stomach and added orange juice and water to symbolise the stomach acids and enzymes to help break up the food into a paste. The food paste then passed into the tights which represented their intestines. Here they squeezed the food to release all of the nutrients into their blood stream. The left-over waste food then passed into a cup [rectum] and squeezed out of the bottom of the cup as a stool. No place for being squeamish in this science class!
