Sub-topic: Definition, Types (Renewable & Non-renewable), Examples, and the Importance of Natural Resources

 

Learning Objectives

By the end of the lesson, learners should be able to:

  • Define natural resources and state examples.
  • Distinguish between renewable and non-renewable natural resources.
  • Describe the importance of natural resources to humans and the environment.
  • Explain how renewable resources are replenished naturally.

 

Previous Knowledge

Learners are familiar with the basic needs of humans and the environment, including food, water, and air, from their studies in lower grades.

 

Instructional Materials

  • Charts showing types of resources
  • Flashcards: renewable vs non-renewable resources
  • Pictures or samples (e.g. small rocks, wood, water in bottles, sun image, etc.)
  • Community resource map (optional)

 

Anticipation (Warm-Up) – 5 minutes

Ask learners:
👉 “What things in nature help us survive every day?”
👉 “Where do we get our food, water, or wood for building from?”

Lead-in: All these things come from natural resources. Today, we will learn about what they are and how we can use them wisely.

 

Building Knowledge (Main Lesson) – 25 minutes

  1. What Are Natural Resources?
    Natural resources are materials provided by nature that humans use for their survival and well-being.

Examples include:

  • Water
  • Forests
  • Soil
  • Minerals
  • Air
  • Animals
  1. Types of Natural Resources:
    👉 Renewable resources are those that can be replaced by nature.
    Examples: sunlight, water, forests, animals, wind.

👉 Non-renewable resources are those that take millions of years to form and cannot be quickly replaced once used up.
Examples: coal, petroleum, natural gas, minerals like gold and iron ore.

  1. Flow of Renewable Resources:
    Renewable resources follow cycles.
  • Water Cycle: rain falls → water flows into rivers → evaporates → forms clouds → rains again.
  • Forests grow back after trees are cut down (if re-planted).
  1. Importance of Natural Resources:
  • Support human life (e.g. air to breathe, water to drink).
  • Provide food, shelter, and energy.
  • Drive agriculture and industry (farming, mining, construction).
  • Aid development (e.g. building roads, making goods).

 

Learners’ Activities

  • Group matching game: Classify items as renewable or non-renewable.
  • Class brainstorm: “What natural resources are found in your community?”
  • Peer discussion: “Which resources do we use the most at home?”

 

Consolidation (Review and Assessment) – 10 minutes

Oral Questions:

  1. What is a natural resource?
  2. Give two examples of renewable and non-renewable resources.
  3. Why is it important to manage our natural resources wisely?

 

Short Notes (For Learners)

Natural resources are things like water, air, forests, and minerals that we get from nature.
There are two types:

  • Renewable: sun, water, wind, forests.
  • Non-renewable: coal, oil, gold.

These resources are very important for our survival, farming, energy, building, and economic growth. We must use them wisely to make sure they last for future generations.

 

Expanded Notes/Instructions

  • Help learners relate natural resources to their homes and community (e.g. well water, firewood, rubber trees).
  • Use a short story: “A community that cut down all its trees and what happened.”
  • Encourage discussion on how their families use resources like charcoal or water.

 

Inclusive/Differentiation

  • Use real-life examples and visuals for visual learners.
  • Roleplay: “What happens if the river dries up?” – for kinesthetic learners.
  • Use storytelling and open questions to engage auditory and interpersonal learners.

 

Homework/Assignment:

  1. Write short notes on renewable and non-renewable resources with 2 examples each.
  2. Interview a parent or elder: “Which natural resource is most important in our community?” Write a short paragraph with their answer.
  3. Bonus: Draw or collect 3 pictures of natural resources in your area and label them.
