Everyone welcome! # Year 6 - Exploring osmosis and diffusion ![](https://files.schudio.com/st-barnabas-primary-school/images/news/413C39B2-2C93-40B3-BCD8-75C51349B819.jpeg) 3 December 2024 Today, year 6 explored how our bodies get the water and nutrients they need through the process of osmosis and diffusion. To highlight these processes, we soaked gummy bears in 3 different liquids (Coca Cola, water and salty water) for 24 hours. We discovered that the gummy bear in the water grew in size because the water molecules moved from a higher concentration (water), to a lower concentration (gummy bear) which is exactly what happens in our bodies. The water in our blood would move into our cells in order to keep us hydrated. However, the gummy bear in the salt shrank. This tells us that if there is too much salt in our blood stream, the water will actually move away from our cells, where it is needed, and back into the blood to restore balance. As a result, we can become dehydrated and our cells become less efficient. ![](https://st-barnabas-primary-school.schudio.com/images/news/413C39B2-2C93-40B3-BCD8-75C51349B819.jpeg) [Year 6](https://www.stbarnabasdarwen.co.uk/news/tag/year-6) [Science](https://www.stbarnabasdarwen.co.uk/news/tag/science) [![](https://files.schudio.com/st-barnabas-primary-school/imagecache/100x100c/news/IMG_1629.JPG)](https://www.stbarnabasdarwen.co.uk/news/2024-12-03-year-5-online-safety-awareness) Previous ### [Year 5 - Online Safety Awareness ](https://www.stbarnabasdarwen.co.uk/news/2024-12-03-year-5-online-safety-awareness) [![](https://files.schudio.com/st-barnabas-primary-school/imagecache/100x100c/news/IMG_5527.jpeg)](https://www.stbarnabasdarwen.co.uk/news/2024-12-03-reception-year-of-prayer) Next ### [Reception: Year of Prayer ](https://www.stbarnabasdarwen.co.uk/news/2024-12-03-reception-year-of-prayer) ### 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/)
