Lesson Number At-Home Activity
(Parental involvement and/or supervision are essential while students carry out these activities.)
Getting Started: Using Electrical Energy Safely and Efficiently

Look around your home and neighbourhood to identify areas where there are potential electrical safety hazards due to the placement of overhead electrical supply wires.

12.1
Investigation: Safety in the Home
  • With parental supervision, identify the location of the distribution panel containing the circuit breakers and/or fuses in your home. Identify the current rating of the circuit breakers and/or fuses.
  • Look around your home or school to identify where power bars are used. Why are power bars used in these instances?

12.2
Distributing Electrical Energy Safely

Look around your home to identify the locations of GFCI outlet sockets. If there are none, suggest locations where a GFCI outlet could improve safety, and why.

12.3
Activity: Practical Circuits

Identify some small appliances and devices around your home that are battery-operated. Use the knowledge and skills you have learned in this activity to carry out an analysis of two appliances or devices, and draw the schematic circuit diagram for each one.

12.4
Making the Most of Energy Resources

Examine the information on the Energuide label on the major appliances in your home. (Note that older appliances may not have these labels.)

12.5
Electrical Energy Use in the Home

Examine a recent electricity usage bill. How might you account for some of the monthly fluctuations that occur in the part of the bill labelled "Energy Management Information"? Discuss this with family members and try to identify ways to reduce energy usage.

12.6
Activity: The Family Energy Audit

Involve your family members in the completion of this activity.

12.7
Case Study: Efficiency, Conservation and Convenience

Examine the light fixtures in your home and determine how many of them use fluorescent bulbs or tubes, including compact fluorescent bulbs. If you find no compact fluorescent bulbs, can you suggest why these are not being used?

12.8
Optimizing the Use of Electrical Energy

Discuss the Try This activity (page 380) with your own family members.

12.9
Activity: Achieving Self-Sufficiency

Identify people or businesses in your community who are using alternative energy resources to produce electrical energy. Contact them for information.

12.10
Explore an Issue: Need More Energy?

Discuss the scenario presented on page 385 with family members. Their insights and viewpoints may help you prepare for your class presentation.

Chapter 12 Review

The Chapter Review (pp. 386-387) in your textbook lists all the Key Expectations you have covered in the chapter and identifies the specific lessons in which the knowledge and skills have been developed.

You can use the Key Expectations list to help you create a personal study guide in preparation for an end-of-chapter test:

  1. Copy down the list of learning expectations from your textbook.
  2. For each learning expectation, locate the appropriate lesson(s) in the unit where the expectation was covered. These are identified in parentheses at the end of each expectation (e.g., 12.2).
  3. Flip to the appropriate lesson(s) for each expectation and make study notes of the key ideas or skills you learned.
