Year 4's Digestive System
This week Year 4 continued their science topic of Animals including Humans by looking at how the digestive system works. They watched a short video explaining how the digestive system works and then watched a live demonstration!
It started with 'eating' bananas and crackers with some water as saliva. It then got mixed with orange juice to replicate stomach acid and all mushed together. After that it went to the small intestine, we got a lot of screams and yucks as it got squeezed through. Then it plopped out and went through the smaller hole in a paper cup. Definitely the highlight of the demonstration.
After the demonstration we then thought about how a piece of food would feel to travel through a digestive system.
