Mini Lesson

The Earth is our shared home — and like any home, it needs to be cared for. One of the most powerful ways every person can help is by understanding what to do with waste.

The 3 Rs: Reduce, Reuse, Recycle

  • Reduce — use less. Buy only what you need; use both sides of paper.
  • Reuse — use again. A glass jar can become a pencil holder; old clothes can be donated.
  • Recycle — turn waste into something new. Paper, plastic bottles, glass, and metal cans can all be recycled into new materials.

What can be recycled?

  • Paper — newspapers, cardboard, clean paper bags.
  • Plastic — bottles and containers marked with a recycling symbol.
  • Glass — bottles and jars (clean and empty).
  • Metal — aluminum cans, tin cans.

What cannot be recycled?

  • Food scraps (these can be composted instead).
  • Greasy or dirty paper (like used pizza boxes).
  • Some plastics — check the number on the bottom.

Why it matters

  • Recycling reduces the amount of waste that goes to landfills.
  • It saves natural resources — recycled paper means fewer trees cut down.
  • Caring for the Earth is a responsibility we all share — children included.
