Everyone welcome! # Year 3 - Science: Clean Coins and Conclusions ![](https://files.schudio.com/st-barnabas-primary-school/images/news/IMG_3502.jpeg) 30 September 2026 Last week in science, the Year 3 class were testing liquids with litmus paper to find out which were acidic and which were alkaline. This week, they used the liquids to soak some dirty coins in order to investigate which liquids were the best at cleaning. They then had to use their results to write a conclusion. They found out that the more acidic liquids were better at cleaning the coins. By the end, we had some lovely, shiny two pence pieces! ![](https://www.stbarnabasdarwen.co.uk/images/news/IMG_3502.jpeg) [Year 3](https://www.stbarnabasdarwen.co.uk/news/tag/year-3) [Science](https://www.stbarnabasdarwen.co.uk/news/tag/science) [![](https://files.schudio.com/st-barnabas-primary-school/imagecache/100x100c/news/IMG_4987(2).jpeg)](https://www.stbarnabasdarwen.co.uk/news/2026-09-29-year-5-art) Previous ### [Year 5 - Art](https://www.stbarnabasdarwen.co.uk/news/2026-09-29-year-5-art) [![](https://files.schudio.com/st-barnabas-primary-school/imagecache/100x100c/news/IMG_8649.jpeg)](https://www.stbarnabasdarwen.co.uk/news/2026-10-01-give-like-dolly-day) Next ### [Give Like Dolly Day](https://www.stbarnabasdarwen.co.uk/news/2026-10-01-give-like-dolly-day) ### Personal Development - [News](https://www.stbarnabasdarwen.co.uk/news) - [Events](https://www.stbarnabasdarwen.co.uk/events) - [Photo Gallery](https://www.stbarnabasdarwen.co.uk/photo-gallery-category/our-gallery) - [Calendar](https://www.stbarnabasdarwen.co.uk/calendar) - [School Council](https://www.stbarnabasdarwen.co.uk/academy-life/school-council) - [Attendance](https://www.stbarnabasdarwen.co.uk/academy-life/attendance) - [Fundraising](https://www.stbarnabasdarwen.co.uk/academy-life/fundraising) - [Extra Curricular Clubs](https://www.stbarnabasdarwen.co.uk/academy-life/clubs) - [Little Leaders](https://www.stbarnabasdarwen.co.uk/academy-life/little-leaders) - [Visits and Visitors](https://www.stbarnabasdarwen.co.uk/visits-and-visitors) - [British Values](https://www.stbarnabasdarwen.co.uk/british-values) - [Protected Characteristics](https://www.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://www.stbarnabasdarwen.co.uk/img/logo/light.png) ](https://www.schudio.com/) ![](https://files.schudio.com/st-barnabas-primary-school/images/events/Open_Days_2026-27_(3).png)
