Grade 2Science

Focus: In this unit, students will trace the path of electricity from the power plant, through their home, and to wall sockets. They will explore different devices that use electricity, as well as safety precautions around the use of electricity. Students will also investigate how magnets are used to produce electricity.

Students are familiar with many devices that use electricity based on day-to-day life. Students understand that certain devices need to be plugged in or turned on to work. However, they may not understand that the power behind that work is generated by electricity because they cannot see it. In fact, the only experience students may have witnessing electricity is while watching a lightning storm. Electricity generated for everyday use often comes from human-made sources like batteries and power plants.

In this unit, students investigate phenomena associated with electricity and magnetism. They will further explore magnetism in Grade 3 Unit 1 Investigating Forces and electricity in Grade 4 Unit 1 Energy Transfer and Transformation.

Students explore concepts that include the following:

  • Identify examples of things people use that require electricity.
  • Express the danger associated with electricity and list safety rules.
  • Compare static and current electricity.
  • Trace the path of electricity in a home from a power plant, through lines, to wall sockets.
  • Compare devices that plug into wall sockets with those that use batteries.
  • Compare and contrast an electric motor that makes a fan spin with a spinning generator that produces electricity.
  • Explore how magnets can make something rotate.
  • Recognize the basic practice of an electrician.

Number of Lessons: 10

  • Lesson time: Most Core Lessons constitute one classroom session of thirty to forty-five minutes. Some lessons cover two or three days of instruction. Some single-day activities and performance tasks might require setting aside a longer block of time.
  • Lesson order: The lessons are coherently sequenced to build from one to the next, linking student engagement across lessons and helping students build new learning on prior knowledge.
  • Because Electricity and Magnetism is not designed to support any specific NGSS Performance Expectation, the instructional episodes are not grouped into multipart lessons. As such, they are identified simply as lessons instead of lesson segments.
  • Please note that a Pacing Guide is provided within the Teacher Guide so teachers can map out customized instructional days for this unit.
