Please see our admissions page for further details. Everyone welcome! # British Science Week- Year 5- Building Sand Timers and Sweet Reactions ![](https://files.schudio.com/st-barnabas-primary-school/images/news/activitymore-C42C186E-B517-499A-B379-48E778F475D3.png) 13 March 2025 This afternoon, Year 5 had a brilliant time getting hands-on with science, exploring time and sweet reactions. First, the children took on the challenge of building their own sand timers. They worked in teams to create timers measuring one, two, and five minutes and then tested them to see how accurate they were. Our Science Ambassador, Mathew, was on hand to support them, and it was fantastic to see the children applying their scientific knowledge and working together. Then, we moved onto a heart shaped sweet experiment. The children investigated what happens when heart-shaped sweets are placed in different liquids: water, vinegar, and a fizzy drink. Before they started, everyone made predictions about what they thought would happen. They then carefully observed the changes, noting how the sweets reacted in each liquid. This led to some lively discussions about dissolving, chemical reactions, and the properties of liquids. It was a fantastic day of scientific exploration, where the children learned about time and chemical reactions whilst enjoying the teamwork and excitement of discovery. We certainly lived life in its fullness, celebrating British Science Week with engaging and educational activities. ![](https://stbarnabasdarwen.co.uk/images/news/activitymore-C42C186E-B517-499A-B379-48E778F475D3.png) [Year 5](https://stbarnabasdarwen.co.uk/news/tag/year-5) [Science](https://stbarnabasdarwen.co.uk/news/tag/science) [![](https://files.schudio.com/st-barnabas-primary-school/imagecache/100x100c/news/0529363B-AA09-4FBE-BE66-EE8C865E48DA.jpeg)](https://stbarnabasdarwen.co.uk/news/2025-03-12-year-6-english) Previous ### [Year 6 English](https://stbarnabasdarwen.co.uk/news/2025-03-12-year-6-english) [![](https://files.schudio.com/st-barnabas-primary-school/imagecache/100x100c/news/IMG_3430.png)](https://stbarnabasdarwen.co.uk/news/2025-03-14-year-2-year-of-prayer) Next ### [Year 2 - Year of Prayer ](https://stbarnabasdarwen.co.uk/news/2025-03-14-year-2-year-of-prayer) ### 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/)
