Over the past few weeks we have been looking at light and it’s properties. We are rounding up the topic with two activities.

1. Making a periscope. These were critical pieces of kit back in WW1 and WW2 to look over the trenches at the enemy. They use reflection to bounce the light to a level which keeps soldiers safe. The children used two mirrors and a cut out to create their own.

2. Making a UV light. The children created a UV light using blue/purple pen to cover their phone light. They then created patterns with highlighters and used their UV lights to make them glow in the dark. This shows that there are still wavelengths of light that are visible in UV light. Which highlighter colour glows the brightest?  (ARTICLE 28)
