About this worksheet
Twelve short actions for Year 4, six safe and six unsafe, set out as cards on page 1. They range from drying hands before touching a switch to poking a metal knife into a toaster and trailing a kettle lead across the cooker. Pupils sort all twelve into a two-column table, then pick the trickiest one and explain the danger. A final question asks for a new safe and unsafe example of their own, a safety rule, and why batteries are safer than mains for school experiments. The answers give the full sort, a rule for each unsafe action and the 230V against 1.5V comparison. It belongs with the Year 4 electricity unit in the England National Curriculum.
