Big Idea

Grade 7

The electromagnetic force produces both electricity and magnetism. 

Grade 9

Electric current is the flow of electric charge.


Learning Objectives

Students will be able to:

  • Identify their existing knowledge about electricity
  • Describe how electricity is relevant to their lives
  • Discuss topics related to energy and electricity usage


Activities

Background Info

‘Hydro’ is the Greek word for water. We’ve used water, like wind, throughout history to provide us with power and energy. The world’s first hydroelectric generating facility was built in Appleton, Wisconsin, in 1882.

Facts about water and electricity

  • Approximately 1.6 billion people around the world do not have electricity in their homes.
  • About 20% of the electricity used throughout the world is generated through hydroelectric power. This electricity meets 5% of the global demand for energy.
  • In B.C., hydroelectric generating stations produce about 80% of the electricity used. BC Hydro’s transmission lines carry electricity from generating stations to substations. From there, electricity is distributed to customers throughout the province. These systems are interconnect with electricity networks in Alberta and the United States.

Electricity in B.C.: The big picture

“Introduction to electricity” shows students the role that electricity plays in their lives and the lives of other people in B.C. Your students will consider their use of electricity and imagine what their lives would be like without it. The goal is to have students recognize the value of clean, renewable electricity through reflection on prior learning, brainstorming, and a trivia game. Having your students creating their own questions around the topics that they are curious about will focus and personalize learning.


Assessments

The activities for this lesson allow for assessment for and of learning, with a Know Wonder Learn graphic organizer that can be used and reviewed throughout the activities. Rubrics for teachers and students to assess group work are provided for two different activities.
