Introduce the concept of electricity by thinking about objects that plug in and turn on.
Play a game of “20 questions” with your students to get them thinking about objects in their lives that use electricity.
No materials needed!
Most electricity in B.C. is generated inside hydroelectric dams. The dam holds back the water in a reservoir and then channels it through large pipes called penstocks. The energy of the falling water is used to turn large wheels called turbines, which then spin generators, which create electricity.
Electricity travels from generators through a network of high-voltage transmission lines to substations near our communities. The substation sends the electricity to the buildings and homes where it is needed over wires called power lines.
The grey cylinders you see on power poles are called transformers. Sometimes these are on the ground in metal boxes called padmount transformers. Transformers lower the voltage of the electricity so it can be safely used in our communities.
As electricity enters our homes, businesses and schools, it passes through a meter. The meter measures the amount of electricity we use. The electricity then flows through wires in the walls and ceilings of our buildings to outlets where it can power our appliances, lights, and other devices.
Assess the ability of your students to ask questions and make predictions about the objects during "20 questions".
Crash, swish, swirl! Do the energy stretch using actions to show how water generates electricity.
A fun activity booklet follows the journey of electricity from a dam to our homes.
Turn a pop bottle, skewers and corks into a model turbine to see how water powers B.C.
