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 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.


Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool.
Develop a simple sketch, drawing, or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem.
Analyze data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of how each performs.
