We used white eggs to set up a comparative test to see which drinks were most likely to stain our teeth. We soaked the eggs in different drinks for 2 days then cleaned them with toothbrushes and toothpaste. Can you spot which drink was our main offender? ![](https://st-barnabas-primary-school.schudio.com/images/news/A31E3D76-CF2D-4707-AA4F-8D5D987AD59A.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/4D0D3E64-042F-4286-9963-BD0E286716BF.jpeg)](https://stbarnabasdarwen.co.uk/news/2022-03-03-year-5-world-book-day) Previous ### [Year 5- World Book Day ](https://stbarnabasdarwen.co.uk/news/2022-03-03-year-5-world-book-day) [![](https://files.schudio.com/st-barnabas-primary-school/imagecache/100x100c/news/F51C4674-3F14-4DC3-9801-5D3D72B1BFEB.jpeg)](https://stbarnabasdarwen.co.uk/news/2022-03-07-jesus-as-a-miracle-worker-worship) Next ### [Jesus as a Miracle Worker Worship ](https://stbarnabasdarwen.co.uk/news/2022-03-07-jesus-as-a-miracle-worker-worship) ### 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/)
