This Science scheme of work video introduces teachers to the skills needed to help Key Stage 2 pupils investigate how well space blankets insulate heat through a comparative test. Pupils wrap warm water bottles in space blankets and measure heat loss over time, comparing results to an unwrapped control. The video walks through the full inquiry cycle – from posing testable questions and planning fair tests to recording data, drawing conclusions, and evaluating reliability. It also supports pupils in plotting line graphs to represent continuous data clearly.

This video is part of Kapow Primary’s Science Making connections resources. It simplifies the process, ensuring teachers feel confident and prepared to support pupils in revisiting core scientific concepts such as insulation, temperature change, and materials. Pupils also explore the real-world application of science through the history and uses of space blankets, helping them connect classroom learning to scientific innovation in action.
