Please see our admissions page for further details. Everyone welcome! # Year 4 - Science: Volume & Amplitude ![](https://files.schudio.com/st-barnabas-primary-school/images/news/IMG_2538.jpeg) 13 May 2026 In Year 4, we are currently studying sound through our science lessons. This week, we were investigating the connection between amplitude and volume. We learned that volume is the loudness of sound and is measured in decibels, and that amplitude measures the height of the sound waves. After playing some digital simulations, we saw that when we increased the volume, the height of the sound waves increased. We then conducted an investigation into whether the height from which an object is dropped would affect the volume of the sound created on impact with the base. The children dropped a marble onto a drum from increasing heights and used a data logger to measure the volume in decibels. They recorded their results and then presented them in a line graph ready to discuss their findings. ![](https://stbarnabasdarwen.co.uk/images/news/IMG_2538.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/IMG_3001.jpeg)](https://stbarnabasdarwen.co.uk/news/2026-05-12-year-6-what-does-community-mean-to-us) Previous ### [Year 6 - What does community mean to us?](https://stbarnabasdarwen.co.uk/news/2026-05-12-year-6-what-does-community-mean-to-us) [![](https://files.schudio.com/st-barnabas-primary-school/imagecache/100x100c/news/IMG_1536(1).jpeg)](https://stbarnabasdarwen.co.uk/news/2026-05-14-dpssa-netball-league) Next ### [DPSSA Netball League ](https://stbarnabasdarwen.co.uk/news/2026-05-14-dpssa-netball-league) ### 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/)
