Lesson details
Key learning points
- There are sensors all around us to detect changes in things like temperature, motion, moisture, light, distance etc.
- Sensors are used in everyday appliances such as washing machines, lights, burglar and fire alarms.
- Strict safety rules must be followed when planning to use electrical components near water.
- Engineers generate ideas to invent, design, and build objects that matter.
Keywords
Switch - A switch is part of an electrical circuit that can stop or allow electricity to flow.
Circuit - An electrical circuit is a closed loop or path that electricity can flow around to make an appliance work.
Sensor - A sensor is a device that can detect and monitor changes.
Detect - To detect something is to discover or notice it.
Design - To design something is to make a plan and a drawing describing how it could be built.
Common misconception
For safety reasons, electrical circuits are never used in systems or appliances which involve the use of or are used near water.
Slides will discuss how engineers plan for the safe use of some electrical appliances near or with water. Pupils will design their own circuit to be used near water.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.

Equipment
This is a design lesson, but it would help if the pupils have access to a range of items that could be used to create a sensor and circuit to monitor water levels in a well. See additional materials.
