Recycling, waste & caring for Earth

1. What should you do before putting an empty glass jar or plastic milk bottle into the recycling bin: rinse it out so food residue does not spoil the paper and cardboard recycling, or smash it on the floor?

2. Why is writing or drawing on both sides of a sheet of paper a good environmental habit: it halves the amount of new paper needed from trees, or it makes the paper heavier?

3. 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?

4. 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?

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

6. 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?

7. Which of the Three Rs means using less of something in the first place (such as turning off a tap while brushing your teeth): Reduce or Recycle?

8. 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?

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

10. What are the “Three Rs” that help us care for the environment and cut down on waste: Reduce, Reuse, Recycle, or Run, Rest, Repeat?

11. What simple habit saves clean drinking water at home every morning and evening: turning off the tap while brushing your teeth, or leaving the hose running?

12. 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?
