Lesson details
Key learning points
- Engineers generate ideas to invent, design, and build objects that matter to improve our lives.
- Strict safety rules must be followed when using electrical components near to water.
- Science is about thinking creatively to try to explain how things work.
- Trial and error is when you try different ways to solve a problem and learn from your mistakes.
Keywords
Design - To design something is to make a plan and a drawing describing how it could be built.
Detect - To detect something is to discover or notice it.
Sensor - Sensors are devices that can detect and monitor changes.
Trial and error - Trial and error is trying different ways to solve a problem and learning from your mistakes until you find a method that works.
Evaluate - To evaluate is to think about what you did and suggest any changes or improvements.
Common misconception
For safety reasons, electrical circuits are never used in systems or appliances which involve or are used near water.
Slides will discuss how engineers plan for the safe use of some electrical appliances near or with water. Children will design their own circuit to be used near water.
Equipment
Children will create a sensor and circuit to monitor water levels in a well. See additional materials.
