Please see our admissions page for further details. Everyone welcome! # British Science Week- Reception- What can we 'Flush Away'? ![](https://files.schudio.com/st-barnabas-primary-school/images/news/Screenshot_2025-03-09_03.11.43.png) 7 March 2025 We have kicked off Science Week with a blast! Miss Kachwalla, our Science Lead initiated a discussion about what can and cannot be flushed down the toilet, encouraging the children to think critically about the impact of their choices. This activity helped develop observational skills and apply knowledge to real-life situations. The class explored key questions, such as: Have you ever flushed any of these items? What happened to them? Which materials broke down when flushed, and which did not? Why is it important to only flush items that break up easily? To investigate further, the Reception class conducted a practical experiment by shaking a bottle containing tissue, paper towel, and toilet paper for 15 seconds. They then observed how each material responded to water, noting which broke down and which remained intact. This helped them understand why only toilet paper, wee and poo should be flushed, while other materials can cause blockages. Science Ambassadors Cassidy and Naomi were on hand to support the lesson, helping to guide discussions and assist with the experiment. As an extra challenge, the children planted mung seeds in a sealed bag with moist cotton wool and used talk tactics to predict what might happen next. Will they disappear? Change colour? Explode? After just 24 hours, the seeds should start to pop open and sprout. Within 3 days to a week, they’ll be fully sprouted, and after a few more days, tiny leaves will start to emerge. This hands-on activity will allow them to observe germination in action and track the changes over time. ![](https://www.stbarnabasdarwen.co.uk/images/news/Screenshot_2025-03-09_03.11.43.png) [Reception](https://www.stbarnabasdarwen.co.uk/news/tag/reception) [Science](https://www.stbarnabasdarwen.co.uk/news/tag/science) [Discussions](https://www.stbarnabasdarwen.co.uk/news/tag/discussions) [![](https://files.schudio.com/st-barnabas-primary-school/imagecache/100x100c/news/41E7EF89-4C11-4883-BC9D-31C0FCFDEDA0.jpeg)](https://www.stbarnabasdarwen.co.uk/news/2025-03-06-year-1-world-book-day-2025) Previous ### [Year 1- World Book Day 2025 ](https://www.stbarnabasdarwen.co.uk/news/2025-03-06-year-1-world-book-day-2025) [![](https://files.schudio.com/st-barnabas-primary-school/imagecache/100x100c/news/activitymore-8B224054-A66B-49D2-B5C7-35BAA3612688.png)](https://www.stbarnabasdarwen.co.uk/news/2025-03-10-mad-science-after-school-club-super-sticky-stuff) Next ### [Mad Science After School Club- Super Sticky Stuff](https://www.stbarnabasdarwen.co.uk/news/2025-03-10-mad-science-after-school-club-super-sticky-stuff) ### 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/)
