Mini Lesson

What happens to banana peels and dry leaves? In a compost bin, tiny living things break them down. Slowly, the scraps turn into dark, rich soil that helps plants grow. Making compost takes a few months, but it is easy to start. You need a mix of greens and browns, a little water, and some air.

🏠 The Life Skills Way (step by step)

  • PICK a bin: a small bin with a lid outside, or a worm bin.
  • ADD greens: fruit and vegetable scraps, coffee grounds, and fresh grass clippings.
  • ADD browns: dry leaves, torn cardboard, paper, and small twigs.
  • MIX it right: add more browns than greens. Browns stop the bin from getting slimy and smelly.
  • KEEP it damp: it should feel like a wrung-out sponge - wet, but not dripping.
  • TURN it: a grown-up helps you mix it with a garden fork to let air in.

🚫 Never in the Compost

  • NO meat, fish, dairy like cheese or milk, or oily food - they smell and bring pests.
  • NO pet waste and nothing plastic.
⚠️

A grown-up helps when you turn the compost with a garden fork - the prongs are sharp. Compost is full of tiny living things, so wash your hands with soap after you work with it.

💡 Handy Tip: keep a small container with a lid in the kitchen for fruit and vegetable scraps. When it is full, carry it out to the bin and cover the scraps with a handful of browns.
