Everyone welcome! # Year 4 - Science: Sound Insulation ![](https://files.schudio.com/st-barnabas-primary-school/images/news/IMG_1287.jpeg) 14 May 2024 Last week, the children designed an investigation to test different materials for their ability to insulate against sound. They learned that soft materials with lots of holes, like foam, are best for absorbing sound. They made their predictions based on this information. This week, the children made their own ear defenders using different materials. They then tested them by holding them to their ears while a drum was played. The children tried out each material and decided which of them made good insulators. The majority of the class agreed that cotton wool and fabric made the best insulators. They found that foil was the worst insulator ![](https://stbarnabasdarwen.co.uk/images/news/IMG_1287.jpeg) [Year 4](https://stbarnabasdarwen.co.uk/news/tag/year-4) [Science](https://stbarnabasdarwen.co.uk/news/tag/science) [![](https://files.schudio.com/st-barnabas-primary-school/imagecache/100x100c/news/4D78E80A-E3E5-4ABB-9851-6A028A277593.jpeg)](https://stbarnabasdarwen.co.uk/news/2024-05-13-year-3-class-worship-passover) Previous ### [Year 3 - Class Worship - Passover](https://stbarnabasdarwen.co.uk/news/2024-05-13-year-3-class-worship-passover) [![](https://files.schudio.com/st-barnabas-primary-school/imagecache/100x100c/news/IMG_8469.jpeg)](https://stbarnabasdarwen.co.uk/news/2024-05-15-online-safety-school-avoidance) Next ### [Online Safety: School Avoidance](https://stbarnabasdarwen.co.uk/news/2024-05-15-online-safety-school-avoidance) ### Personal Development - [News](https://stbarnabasdarwen.co.uk/news) - [Events](https://stbarnabasdarwen.co.uk/events) - [Photo Gallery](https://stbarnabasdarwen.co.uk/photo-gallery-category/our-gallery) - [Calendar](https://stbarnabasdarwen.co.uk/calendar) - [School Council](https://stbarnabasdarwen.co.uk/academy-life/school-council) - [Attendance](https://stbarnabasdarwen.co.uk/academy-life/attendance) - [Fundraising](https://stbarnabasdarwen.co.uk/academy-life/fundraising) - [Extra Curricular Clubs](https://stbarnabasdarwen.co.uk/academy-life/clubs) - [Little Leaders](https://stbarnabasdarwen.co.uk/academy-life/little-leaders) - [Visits and Visitors](https://stbarnabasdarwen.co.uk/visits-and-visitors) - [British Values](https://stbarnabasdarwen.co.uk/british-values) - [Protected Characteristics](https://stbarnabasdarwen.co.uk/protected-characteristics) ##### Location Knowlesly Road Darwen Lancashire BB3 2JA ##### Contact Us 01254 702996 ##### Stay Connected - [Facebook](https://www.facebook.com/stbarnabasce/) - [X](https://twitter.com/stbarnabasce) © Copyright 2021–2026 St Barnabas Primary School, A Church of England Academy School & Trust Websites by [ ![Schudio logo](https://stbarnabasdarwen.co.uk/img/logo/light.png) ](https://www.schudio.com/)
