Save the Energy! Investigating Electricity Consumption at Home

Introduction

Have you ever wondered why your electric bill increases when appliances are used more often? Electricity powers our homes, schools, and communities, but using it efficiently is important for saving money and protecting the environment.

In this activity, students will investigate how different household appliances consume electricity and discover ways to reduce energy consumption.

Task

WHAT TO DO:

You are an Energy Auditor assigned to help families use electricity wisely.

Your task is to create a digital infographic, poster, or presentation that answers the essential question:

"Which household appliances consume the most electricity, and how can we reduce electricity usage?"

End Product

Your output should include:

  • Common household appliances and their energy consumption
  • Factors that affect electricity use
  • Tips for conserving electricity
  • Recommendations for reducing energy costs

Process

Step 1: Ask Questions

Investigate the following:

  • What is electricity consumption?
  • Which appliances use the most electricity?
  • How is electricity measured?
  • What habits can increase electricity usage?
  • How can electricity be conserved?

Step 2: Conduct Online Research

Use the resources provided to gather information about electricity usage in homes.

Step 3: Collect Data

Create a table like the one below:

Appliance Estimated Power Rating (W) Hours Used per Day High, Medium, or Low Consumption
Refrigerator      
Electric Fan      
Television      
Air Conditioner      
Rice Cooker      

Step 4: Analyze Your Findings

Answer the following:

  1. Which appliance consumes the most electricity?
  2. Which appliance consumes the least electricity?
  3. What can families do to reduce electricity consumption?

Step 5: Create Your Product

Using Canva, PowerPoint, or Google Slides, create an infographic or 5-slide presentation showing:

  • Your findings
  • Graphs or charts
  • Energy-saving recommendations

Step 6: Reflection

Write a short paragraph answering:

"What energy-saving practices can you start doing at home today?"
