In this lesson, students devise their own flood warning device and create a technical brief for an international audience using recognised circuit symbols. They also consider how people both here and in Nepal can best prepare for floods. Heavy monsoon rains can devastate communities in Nepal. The severe flooding leaves families destitute with homes, stored food, cultivated land and livestock destroyed. Lives are frequently lost. But now, with advanced warning systems in place in some areas, communities are able to prepare themselves and lives are being saved. During the lesson, students will: • use their understanding of conductors and simple circuits to design a flood alarm circuit • use their understanding of series and parallel circuits to create a combined warning and alarm circuit • use circuit symbols to create a technical brief for their design
