Students should understand how human activities impact the environment through the extraction, use, disposal, and recycling of materials.
Key Concepts & Examples
  • Sustainability – Using resources responsibly so they last for future generations.
    • Example: Using energy-efficient LED bulbs instead of traditional ones.
  • Extraction – Removing natural resources from the Earth.
    • Example: Mining for metals like iron and copper to make cars and electronics.
    • Example: Cutting down trees for paper and furniture.
  • Use – How materials are used in everyday life.
    • Example: Plastic is used for packaging and bottles.
    • Example: Aluminium is used for drink cans.
  • Disposal – What happens when products are thrown away.
    • Example: Plastic waste in landfills takes hundreds of years to break down.
    • Example: Electronic waste (old phones, laptops) can release harmful chemicals.
  • Recycling – Reusing materials to reduce waste and conserve resources.
    • Example: Recycling paper reduces the number of trees cut down.
    • Example: Glass bottles can be melted and reshaped into new bottles.
Ways to Improve Sustainability
  • Reduce waste by using reusable bags, bottles, and containers.
  • Recycle materials like paper, plastic, and metal instead of throwing them away.
  • Reuse items instead of buying new ones (e.g., using glass jars for storage).
  • Choose renewable resources like solar and wind energy instead of fossil fuels.
  • Support sustainable businesses that use eco-friendly materials.
