Everyone welcome! # Year 6 Science - Does the number of components affect the output of a circuit? ![](https://files.schudio.com/st-barnabas-primary-school/images/news/61B10100-4CF8-4220-A63A-F81282785271.jpeg) 23 September 2024 In science, year 6 have been investigating whether the number of components in a circuit affects the output. To ensure this was a fair test we had a control test, which consisted of a battery, wires and a light bulb, and made sure only one variable was changed throughout the investigation: the number of bulbs. We noticed that as we added more bulbs, the dimmer they got. This is because the more components you have, the more resistance there is in the circuit. ![](https://stbarnabasdarwen.co.uk/images/news/61B10100-4CF8-4220-A63A-F81282785271.jpeg) [Year 6](https://stbarnabasdarwen.co.uk/news/tag/year-6) [Science](https://stbarnabasdarwen.co.uk/news/tag/science) [![](https://files.schudio.com/st-barnabas-primary-school/imagecache/100x100c/news/7CD2BCAA-5B4C-4B48-B116-09DB4754F222.jpeg)](https://stbarnabasdarwen.co.uk/news/2024-09-20-reception-pe-jumping-skills) Previous ### [Reception PE - Jumping Skills](https://stbarnabasdarwen.co.uk/news/2024-09-20-reception-pe-jumping-skills) [![](https://files.schudio.com/st-barnabas-primary-school/imagecache/100x100c/news/IMG_2217.jpeg)](https://stbarnabasdarwen.co.uk/news/2024-09-24-rev-ben-s-worship-god-the-rescuer) Next ### [Rev Ben’s Worship: God the Rescuer](https://stbarnabasdarwen.co.uk/news/2024-09-24-rev-ben-s-worship-god-the-rescuer) ### 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/)
