Recycling, waste & caring for Earth

1. Which of the Three Rs means turning used materials (like old newspapers, glass jars or aluminium cans) into brand-new products: Recycle or Burn?

2. What type of light bulb uses much less electricity and lasts much longer than an old filament bulb: an LED bulb or a wax candle?

3. Why is buying a refillable water bottle better for the planet than buying a new disposable plastic bottle every day: one reusable bottle replaces hundreds of single-use plastic bottles each year, or disposable bottles are heavier?

4. How does planting trees in a community or along a shoreline help the environment: tree roots hold soil in place and leaves absorb carbon dioxide while releasing oxygen, or trees block the rain?

5. Instead of throwing out clothes or storybooks you have outgrown that are still in good condition, what is a sustainable choice: donate or pass them on to younger learners, or burn them?

6. Why should used household batteries and old electronics be taken to a special collection point rather than thrown in ordinary rubbish: they contain metals and chemicals that can leak into soil and water, or they float away?

7. How does collecting rainwater from a roof into a covered water tank help a household: the stored rainwater can water gardens and flush toilets without using treated mains water, or it stops clouds forming?

8. What does the word “biodegradable” mean: capable of being broken down naturally by bacteria, fungi and other living decomposers, or made of steel?

9. Which of these materials can be recycled over and over again without losing its strength: an aluminium drink can or a greasy paper napkin?

10. Why do swimmers and snorkellers avoid standing on or touching live coral when visiting a reef: coral polyps are fragile living animals that are easily crushed or damaged, or coral is made of rubber?

11. What happens to old glass bottles when they are sent to a glass recycling plant: they are crushed, melted in a furnace and moulded into new glass bottles and jars, or they are turned into wood?

12. What natural soil conditioner is made when kitchen fruit and vegetable scraps and fallen leaves rot down in a garden bin: compost or plastic?
