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

When a Year 3 and Year 4 class is preparing for a special science assembly, an unexpected power cut plunges the school hall into darkness. Rather than panic, the pupils become young scientists, working together to investigate what electricity is, where it comes from and how it powers our everyday lives. Along the way, they meet a colourful cast of scientists, engineers and even talking electrical objects, discovering how circuits work, why electricity needs a complete path and how to stay safe around electrical equipment.

Designed specifically for Lower Key Stage 2, this ready-to-perform assembly combines exciting storytelling with engaging scientific learning, helping pupils develop a secure understanding of electricity while encouraging curiosity, teamwork and responsible energy use.
