Subject: Basic Science And Technology

Curriculum Theme: Basic Science

Topic: ENVIRONMENTAL CHANGES

Content: Effects and control of erosion

Specific Objectives:
By the end of the lesson, pupils should be able to:

1. State 3 effects of erosion.
2. List 3 ways for controlling erosion.

Reference Materials:

• 9 – Years Basic Education Curriculum
• Abuja Educational Resource Centre Scheme of work
• NAPPS National Unified Scheme of Work
• Course Book
• Online Information
• Textbooks (List your relevant textbook here)

Instructional Materials:

• Charts and photographs of erosion effects
• Whiteboard and markers
• Chalk and chalkboard
• Projector and screen (if available)
• Pen and paper for note-taking
• Models or props for demonstrating erosion control measures

Rationale for the Lesson:
Understanding the effects of erosion and how to control it is essential for preserving the environment, ensuring soil fertility, and preventing disasters like landslides and floods. It’s also important for sustainable agriculture.

Prerequisite/Previous Knowledge:
Students are expected to have a basic understanding of erosion, as covered in the previous lesson.

INSTRUCTIONAL PROCEDURES:

Content Development: Effects and Control of Erosion

Note to Pupils:

Effects of Erosion:

1. Soil infertility: Erosion can wash away the fertile topsoil, making it difficult for plants to grow.
2. Landslides: Erosion can lead to the collapse of slopes, causing landslides in hilly areas.
3. Floods: Erosion can clog rivers and streams, increasing the risk of flooding during heavy rains.
4. Loss of fertile topsoil: Erosion removes the nutrient-rich topsoil essential for agriculture.
5. Damage to property and infrastructure: Erosion can harm buildings, roads, and other structures.

Control of Erosion:

1. Afforestation: Planting trees and grass helps hold the soil together and prevent erosion.
2. Terracing: Creating steps on slopes reduces the speed of water runoff, preventing soil loss.
3. Retaining walls: Building walls can help hold back soil and prevent erosion.
4. Using cover crops: Planting crops like clover or rye can protect the soil from erosion.
5. Proper land management: Techniques like crop rotation and contour farming reduce erosion risks.

Evaluation:

1. What are the effects of erosion?
2. List two control measures for erosion.
3. How does afforestation help control erosion?

Note to Teachers:
Customize the teaching methods and activities based on your curriculum, resources, and students’ needs. Ensure active student participation and engagement throughout the lesson.
