Year 4's Practical Science Experiment of the Digestive System (Enquiry skills: Research & Identifying, grouping and classifying)

Today in Year 4, we made our own digestive system using different ingredients and apparatus. First we broke up a slice of bread to model the idea of our teeth grinding up food into smaller pieces. Then we mashed up a banana and added water to create the idea of saliva. We used a funnel to represent the oesophagus and emptied this into our stomach (bag filled with orange juice). Lastly we used a pair of tights as our intestines. The children thoroughly enjoyed this lesson and actively taking part in being the different digestive organs!

After researching this topic over the last week, it was a great opportunity for the children to apply their subject knowledge. The children were able to confidently identify the main organs within the digestive system and explain the different roles they had to break down food. Fantastic work Year 4! ☺

'I liked looking at the food being squished in the orange juice which we used to represent stomach acid. We mixed it in a plastic bag to make it look like the stomach.'        Krystian
