Lesson Plan: Rivers - Pollution

Subject: Geography
Grade: Year 4
Duration: 30 minutes

Lesson Objectives

By the end of this lesson, students will be able to:

• Understand what river pollution is and its causes.
• Identify different types of pollutants found in rivers.
• Discuss the impact of pollution on river ecosystems.
• Explore ways to prevent river pollution.

Materials Needed

• Whiteboard and markers
• Pictures of polluted rivers and clean rivers
• Chart paper and markers for group work
• Worksheets on river pollution
• Short video on river pollution (optional)

Introduction (5 minutes)

1. Engage the Class

   • Begin the lesson by asking students what they know about rivers. Use questions like:
     • "What rivers can you name?"
     • "Have you ever seen a river? What did it look like?"

2. Introduce the topic

   • Explain that today, they will learn about pollution in rivers. Show a few pictures of polluted rivers and ask how they feel when they see them.

Learning Activities

Part 1: What is River Pollution? (10 minutes)

• Definition
  Write the definition of river pollution on the board. Explain:

  • River pollution occurs when harmful substances are introduced into water bodies, making them dirty and unsafe for wildlife and humans.

• Types of Pollutants
  Discuss different types of pollutants, such as:

  • Chemical waste (e.g., industrial discharge)
  • Plastic waste (e.g., bottles and bags)
  • Sewage (e.g., waste from homes)
  • Agricultural runoff (e.g., fertilizers and pesticides)

• Group Discussion
  Divide the class into small groups and have them identify other sources of pollution they may know about. Each group can share their ideas briefly.

Part 2: Impact of Pollution (5 minutes)

• Ecosystem Effects
  Explain how pollution affects river wildlife, including fish and plants. Discuss:

  • Polluted water can harm or kill fish and animals.
  • It can also destroy their habitats and food sources.

• Human Impact
  Discuss how polluted rivers can affect people, such as:

  • Contaminated drinking water.
  • Loss of recreational spaces.

Part 3: Prevention of River Pollution (5 minutes)

• Discussion on Solutions
  Ask the class how they think we can help to reduce river pollution. Discuss solutions:

  • Proper disposal of waste.
  • Use of biodegradable materials.
  • Cleaning up local rivers.

• Worksheet Activity
  Provide a worksheet for students to write down 2-3 ideas on how they can help prevent river pollution.

Conclusion (5 minutes)

1. Recap the Lesson
   Summarise key points about river pollution, its effects, and how to prevent it.

2. Reflection
   Ask students to share one new thing they learned today. Encourage them to think about ways they can be more environmentally friendly.

Assessment

• Observe group participation during discussions.
• Review completed worksheets to assess understanding of the topic.

Extension Activity (Optional)

For homework, students can be asked to draw a picture of a clean river and label what they see in it. This will reinforce their learning about what a healthy river looks like compared to a polluted one.
