Mrs Hurley and Mrs McKenna would like to welcome you to the Year 4 page.
I hope you all had a lovely Easter break. We have got lots of exciting learning planned for this half term. There will be many opportunities for outdoor learning this half term as we aim to continue to consolidate the skills we have already learnt as well as learning lots of new things!
You can see this term's topic web on the link above:)
This term in year 4 we are learning about Teeth and Digestion in our topic entitled, ‘The Art of Food’.
We looked at teeth first and the effect soft drinks have on our teeth! As a class we conducted a science experiment over the course of 1 week using real teeth and drinks such as cola, diet cola, apple juice and water, and completed a daily log of what had happened to the teeth. The results were quite surprising!
We then moved onto digestion, the children thought about what we have inside our bodies to help us digest our food. We played a memory game where the children had to remember what they had seen and read and then report back to their team and draw their findings on the team body. It was a really fun lesson.
Carrying on with teeth and digestion, we carried out an experiment to recreate what happens to our food once it’s inside our body. Starting with when food goes in our mouths, the children used scissors to simulate what our teeth do to chew our food. Bananas and biscuits were the meal of the day!
Saliva was added (water really!) and the cutting commenced!
Following this, the process of swallowing and food going down the oesophagus was recreated and into the stomach by pushing the mushed up food into a bag by squeezing through rolled up greased proof paper, the bag represented the stomach.
The contents of the stomach were then forced into the small intestine and then the large intestine which was represented by using tights. This is where it got messy!
After passing through the small and large intestine the food was pushed through a hole in the tights and out through the anus. The results were as you can imagine….
We had so much fun doing this experiment and the children were able to show their parents what they had produced.
