We also carried out an investigation to find out which material would be best suited to use as curtains to block out the light in a child’s bedroom. We used a torch and a big white card at the opposite end, placing three different materials between them. Only one made a dark shadow, so that was the one that would be best to use. It was opaque. The other two were translucent and transparent. ![](blob:https://st-barnabas-primary-school.schudio.com/868b7282-bdff-4533-8f11-c79a55500830) [Year 3](https://stbarnabasdarwen.co.uk/news/tag/year-3) [Science](https://stbarnabasdarwen.co.uk/news/tag/science) [![](https://files.schudio.com/st-barnabas-primary-school/imagecache/100x100c/news/9CC2819B-DC3D-4EAF-9D7D-8106A84DF1E1.jpeg)](https://stbarnabasdarwen.co.uk/news/2022-05-20-celebration-worship) Previous ### [Celebration Worship](https://stbarnabasdarwen.co.uk/news/2022-05-20-celebration-worship) [![](https://files.schudio.com/st-barnabas-primary-school/imagecache/100x100c/news/5A8F7DB9-E8AC-437F-9914-72012A7B9DDB.jpeg)](https://stbarnabasdarwen.co.uk/news/2022-05-24-year-4-les-opinions) Next ### [Year 4 - Les Opinions](https://stbarnabasdarwen.co.uk/news/2022-05-24-year-4-les-opinions) ### 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/) ![](https://files.schudio.com/st-barnabas-primary-school/images/events/Open_Days_2026-27_(3).png)
