To finish off our topic on sound, the children were set a task to design and make some ear defenders. The main objective was to find out which materials were the best to use to muffle or reduce sound.
The children looked closely at the resources available and then made predictions. They had to think carefully about making their tests fair.
- “I think that cotton wool will be best because you can pack it into all the space.”
- “The ear defenders need to fit securely to your head otherwise sound can still travel through to your ears.”
Time to get going ….
Time to test the ear defenders…

What a laugh we had! Ask your child to find out what happened.
Cooking with sound?
Year 4 staff and children thought about what ingredients, whilst cooking, would create sound. We came up with popcorn.
Honey and popcorn flapjacks
The children had to listen carefully to the sound of the popping corn and describe it. We all had great fun and the noisy flapjack tasted delicious!
- “I’ve had the best lesson ever.”
- “I understand how sound travels now.”
- “This learning has been great fun!”
Well done to all the children and many thanks to Mrs Pearson and Mrs Charlesworth for all their hard work. It has been a fun, and sometimes noisy, mini topic. We all now need some peace and quiet so enjoy the half term break.
