After planning their investigation and making predictions, the children carried out an experiment to compare soft, medium and hard toothbrushes. Working collaboratively, they took on different roles within their groups, including brushers, timers and observers, to help ensure the investigation was carried out fairly. The children repeated their tests with each type of toothbrush to help make their results more reliable. They then recorded their findings in a table so they could compare the results and see which toothbrush was the most effective. Well done, Year 4, for working so well as a team and developing your skills in planning investigations, carrying out fair tests and recording scientific results. --- ### Year 4 Science - Investigating Toothbrush Effectiveness [![](https://files.schudio.com/burtonwood-community-primary-school/imagecache/720x720s/gallery/year-4-science-investigating-toothbrush-effectiveness/Screenshot_2026-10-22_100244(1).png)](https://files.schudio.com/burtonwood-community-primary-school/images/gallery/year-4-science-investigating-toothbrush-effectiveness/Screenshot_2026-10-22_100244(1).png) [![](https://files.schudio.com/burtonwood-community-primary-school/imagecache/720x720s/gallery/year-4-science-investigating-toothbrush-effectiveness/Screenshot_2026-10-22_100339.png)](https://files.schudio.com/burtonwood-community-primary-school/images/gallery/year-4-science-investigating-toothbrush-effectiveness/Screenshot_2026-10-22_100339.png) [![](https://files.schudio.com/burtonwood-community-primary-school/images/gallery/year-4-science-investigating-toothbrush-effectiveness/Screenshot_2026-10-22_100406.png)](https://files.schudio.com/burtonwood-community-primary-school/images/gallery/year-4-science-investigating-toothbrush-effectiveness/Screenshot_2026-10-22_100406.png) [![](https://files.schudio.com/burtonwood-community-primary-school/imagecache/720x720s/gallery/year-4-science-investigating-toothbrush-effectiveness/Screenshot_2026-10-22_100521.png)](https://files.schudio.com/burtonwood-community-primary-school/images/gallery/year-4-science-investigating-toothbrush-effectiveness/Screenshot_2026-10-22_100521.png) [![](https://files.schudio.com/burtonwood-community-primary-school/imagecache/720x720s/gallery/year-4-science-investigating-toothbrush-effectiveness/Screenshot_2026-10-22_100544.png)](https://files.schudio.com/burtonwood-community-primary-school/images/gallery/year-4-science-investigating-toothbrush-effectiveness/Screenshot_2026-10-22_100544.png) [![](https://files.schudio.com/burtonwood-community-primary-school/imagecache/720x720s/gallery/year-4-science-investigating-toothbrush-effectiveness/Y4_5(1).png)](https://files.schudio.com/burtonwood-community-primary-school/images/gallery/year-4-science-investigating-toothbrush-effectiveness/Y4_5(1).png) [ Reception - Celebrating Diwali](https://burtonwoodcp.co.uk/news/2026-10-21-reception-celebrating-diwali) [Halloween Disco 2026 ](https://burtonwoodcp.co.uk/news/2026-10-23-halloween-disco-2026) ### Our School - [Welcome from our Headteacher](https://burtonwoodcp.co.uk/our-school/welcome-from-our-headteacher) - [About our School](https://burtonwoodcp.co.uk/our-school/about-our-school) - [Our News](https://burtonwoodcp.co.uk/news) - [Values, Vision and Mission Statement](https://burtonwoodcp.co.uk/our-school/values-vision-missionstatement) - [Open Events](https://burtonwoodcp.co.uk/our-school/open-events) - [Virtual Tour](https://burtonwoodcp.co.uk/our-school/virtual-tour) - [Our Staff](https://burtonwoodcp.co.uk/our-school/staff) - [Admissions](https://burtonwoodcp.co.uk/our-school/admissions) - [Governance](https://burtonwoodcp.co.uk/our-school/governors) - [School Prospectus](https://burtonwoodcp.co.uk/our-school/school-prospectus) - [Policies and Reports](https://burtonwoodcp.co.uk/our-school/policies) - [School Performance Data](https://burtonwoodcp.co.uk/our-school/school-performance-data) - [Ofsted and Academic Results](https://burtonwoodcp.co.uk/our-school/Ofsted-and-Academic-Results) - [The Equality Act](https://burtonwoodcp.co.uk/student-support/the-equality-act) - [Work for Us](https://burtonwoodcp.co.uk/our-school/work-for-us1) - [Omega MAT](https://omegamat.co.uk/) - [Contact Us](https://burtonwoodcp.co.uk/contact) ![Burtonwood Community Primary School](https://files.schudio.com/burtonwood-community-primary-school/images/logo/Omega_Part_of_Logo_White_Mono.png) **Burtonwood Community Primary School** Green Lane Burtonwood Warrington WA5 4AQ Tel: 01925 224072 Email: ## Follow Us - [Facebook](https://www.facebook.com/profile.php?id=100090550038773&locale=en_GB) - [LinkedIn](https://www.linkedin.com/company/omega-multi-academy-trust) - [Instagram](https://www.instagram.com/burtonwoodcps) ## Translation © Copyright 2020–2026 Burtonwood Community Primary School School & Trust Websites by [ ![Schudio logo](https://burtonwoodcp.co.uk/img/logo/light.png) ](https://www.schudio.com/) Update cookies preferences
