Year 4 have been focusing on the digestive system in Science. We have been learning about the different parts of the digestive system and their functions. As part of this we conducted a gruesome experiment in which we had to re-create the digestive system using food, acid (apple juice), bags, a stocking and a plastic cup!
After completing our experiment, we discussed the following questions:
What would happen if we didn’t have saliva?
Why do you think some foods take longer to pass through the digestive system than others?
