Tracking time with shadows

This Science scheme of work video introduces teachers to the skills needed to help Key Stage 2 pupils understand how to calibrate and use a sundial to track the movement of the Sun. Pupils learn how to align the gnomon with true North and record shadow positions to mark the hours, either outdoors using sunlight or indoors with a torch-based model. The video offers clear guidance on practical setup and simplifies concepts such as solar time for effective classroom delivery.

This video is part of Kapow Primary’s Science Space resources. It simplifies the process, ensuring teachers feel confident and prepared to support pupils in applying scientific methods to explore timekeeping, the Earth’s rotation, and observational science in lessons like the one below.
