Our Wonder questions…
Human Digestive System
Year 4 have been learning about the digestive system and have carried out an experiment to mimic human digestion.
To help us understand how our bodies break down food, Mrs Ilyas introduced what may just be the most revolting – but also the most memorable – experiment we’ve ever done in the classroom. The aim? To build a working model of the human digestive system… using real food!
The process began with some “chewing”: we crushed up crackers and bananas to represent the start of digestion in the mouth. Once our mixture was ready, it was placed into a plastic bag (our “stomach”), where sparkling water was added to act as stomach acid. The bag was sealed, squished, and mixed thoroughly – just like food in your tummy!
After this, things got even messier. We poured the contents from our ‘stomachs’ into a pair of tights to represent the intestines. This part of the experiment involved pushing out all the nutritious liquid (absorbed nutrients) into a bowl, mimicking what our real intestines do.
And finally… the grand finale. We turned over the tights to push out the final waste product – poo! By this stage, the classroom was filled with a very unique smell and a mix of wide-eyed fascination and scrunched-up noses.
