Detailed notes • Activities • Important questions • Competency questions • MCQs • Worksheet • Quick revision
Chapter focus: Nature provides many resources that support life and human activities. Understanding their value helps us use them carefully and protect them for the future.
🎯 Learning Goals
- Identify important natural resources.
- Understand renewable and non-renewable resources at an introductory level.
- Recognise how water, air, soil, forests, minerals and sunlight support life.
- Explain why resources need conservation.
- Connect human activities with environmental changes.
- Suggest practical conservation measures.
🌍 1. What Are Nature’s Treasures?
Nature’s treasures are the useful materials, substances, living organisms and environmental conditions that occur in nature and support life. Air, water, soil, sunlight, plants, animals and minerals are examples.
💧 2. Water as a Resource
Water is essential for drinking, agriculture, sanitation, ecosystems and many human activities. Although Earth has abundant water, usable freshwater is limited and unevenly distributed. Avoiding wastage, protecting water bodies and using water efficiently are important.
🌬️ 3. Air and the Atmosphere
Air provides gases needed by organisms and supports processes such as respiration and combustion. Plants use carbon dioxide in photosynthesis. Air pollution can affect organisms and ecosystems.
🌱 4. Soil
Soil supports plant growth and contains mineral particles, organic matter, air and water. Healthy soil is important for agriculture and terrestrial ecosystems. Erosion and inappropriate land use can reduce soil quality.
🌳 5. Forests and Biodiversity
Forests provide habitats, food, materials and ecosystem services. They help maintain biodiversity and influence local environmental conditions. Protecting habitats helps conserve many species.
☀️ 6. Sunlight and Energy
Sunlight is a major source of energy for Earth’s systems. Green plants capture light energy during photosynthesis, supporting food chains.
⛏️ 7. Minerals and Materials
Minerals are natural resources used in construction, manufacturing and technology. Many mineral resources are finite, so responsible extraction, efficient use, reuse and recycling can reduce pressure on natural systems.
♻️ 8. Conservation
Conservation means careful management and protection of natural resources. Simple actions include reducing unnecessary consumption, reusing materials, recycling where suitable, saving water and electricity, protecting vegetation and avoiding pollution.
🔬 9. Explore and Observe
- List natural resources used in your home during one day.
- Record where water is used and identify one way to reduce wastage.
- Observe a nearby green space and list living and non-living components.
- Compare a reusable item with a single-use alternative.
🧠 Think Like a Scientist
- Why can a resource be abundant in nature but still scarce for human use?
- How can protecting forests help organisms other than trees?
- Why is soil considered an important natural resource?
- How can everyday choices reduce pressure on natural resources?
- Why is conservation a shared responsibility?
📝 Important Practice Questions

- Design a school campaign for saving one natural resource.
- Explain why recycling alone cannot replace reducing unnecessary consumption.
- Propose a practical plan to reduce water wastage at school.
