Wk.#8: Electricity & Circuits

Week #8: Electricity & Circuits

Objectives

  • Identify examples of electrical devices in the home
  • Construct and test simple circuits
  • Demonstrate multiple ways to build a circuit including two or more functions (lights, buzzers, switches)
  • Test materials for being conductive

Activities

  • Learners discussed examples of electrical devices.
  • Learners constructed circuits using a breadboard, starting with a simple circuit to power a light bulb and adding additional elements including switches and speakers.
  • Learners used their circuit to test and organize materials as conductive and non-conductive.
  • Learners used devices to test battery strength.
  • Learners explored using the tested materials to construct their own LED circuit.

Questions to Discuss

  • What three materials worked best as conductors?
  • Why are switches important to many electrical devices?
  • What harm can a short circuit do?

Things to Try at Home

  • Ask an adult how much electricity your home uses in a month and how much that costs. Is it more or less than you expected? Is there anything that you do to help reduce that amount of electricity used? Why is it important to be aware of the energy we use?
  • Search for three different ways that electricity is produced in Canada. What resources are needed for each of them? Which method of electrical production do you think Canada should be primarily using?

  • Interview someone who works with electricity or electronics. Ask them questions about what some of the dangers are when working with electricity, what do they do to keep safe from electricity, and how do they test if an electrical device is working or not.
