KS3 Geography: Understanding Electricity Generation

Introduction

Electricity is essential in our daily lives. We use it for many things, from lighting our homes to powering our devices. In this lesson, we will explore how electricity is generated and transported to our homes, and compare different natural resources used for electricity generation.

1. List of Ways You Have Used Electricity Today

Take a moment to think about how you’ve used electricity today. Write a list of everything you can remember. Here are some examples to get you started:

• Turning on the lights
• Using a computer or tablet
• Charging your phone
• Watching TV
• Using the microwave

Tip:

Keep your list specific! Instead of just writing “used devices,” mention which devices you used.

2. How Electricity Gets from the Power Station to Your Home

Electricity travels a long way from power stations to your home. Here’s a simple explanation:

1. Generation: Electricity is generated at a power station using different resources, like coal, wind, or solar.
2. Transmission: It travels through high-voltage power lines to reduce energy loss.
3. Distribution: Finally, it reaches your home through lower-voltage lines, so you can use it safely.

Activity:

Write a short paragraph explaining this process in your own words.

3. Comparing Natural Resources for Electricity Generation

a) Match Photos with Descriptions

Look at Photos 8-1 and descriptions in J. Try to match each photo to the right natural resource used for generating electricity.

b) Complete the Table

You will now compare different natural resources used for electricity generation. Here’s an example table to help you:

| Resource | Renewable or Non-renewable | Earth’s Sphere | Advantages | Disadvantages |

|———————-|—————————-|—————-|————————————-|———————————–|

| Uranium (Nuclear) | Non-renewable | Lithosphere | Efficient, can produce electricity continuously | Radioactive leaks, expensive to build |

c) Discuss with a Partner

Work with a partner to discuss the advantages and disadvantages of renewable and non-renewable energy sources. Fill in your table together.

d) Government Recommendation

Imagine you are a government adviser. Think about what you would recommend for the UK’s future electricity generation. Consider the importance of renewable energy sources for a sustainable future.
