Students explore concepts of electricity, electric circuits, and electromagnetism to develop an understanding of how to create and regulate the flow of electricity through circuits.

 

Students must use this knowledge to create two signalling devices to ensure that they can be rescued off the desert island that they are trapped on   

 

Key tasks

 

• Food power. Students generate electricity using food as their power source. They experiment with different foods to determine which ones are best suited to producing and sustaining an electric current 

​​

• Homopolar motor. Students explore the concept of electromagnetism by creating a homopolar motor to generate electricity through the movement of a magnet
