LKS2 Light Class Assembly Script | Updated for 2026-27

Bring one of Lower Key Stage 2’s most engaging science topics to life with this inspiring, interactive and curriculum-linked class assembly.

When a sudden blackout interrupts the school day, a group of Year 3 and Year 4 pupils sets out to discover why light is so important. As they investigate different sources of light, from the Sun and stars to torches and electricity, they also discover that light can represent kindness, hope and teamwork. Working together to solve problems and support their community, the children realise that even the smallest act of kindness can brighten someone’s day.

Designed specifically for Lower Key Stage 2, this ready-to-perform assembly combines engaging storytelling with meaningful scientific learning, helping pupils understand how light helps us see, stay safe and explore the world while encouraging empathy and positive citizenship.
