The Kitchen Garden / module 2 of 3

Compost: Turning Waste into Soil

By OSH Founding Team✓ Verified by OSH Review Panel

The child starts a small compost pot from kitchen scraps and watches waste become the food their next plants will eat.

Guide

Set up a bucket or old pot with drainage holes. Rule: greens (peels, vegetable scraps) and browns (dry leaves, cardboard bits) in rough layers, never meat or oil. The child is compost keeper: adding scraps, stirring weekly, and reporting the smell and heat. When the child asks why it gets warm, resist explaining immediately; ask what they think is happening in there first.

Material

  • Compost keeper checklist: what goes in, what stays out (platform library)

Activities

Daily: scrap sorting after meals into compost and rubbish. Weekly: stir, observe, and one journal line. Experiment: bury one plastic wrapper and one leaf at the edge, dig both up after a month, and compare.

You will need

An old bucket or pot, kitchen scraps, dry leaves. Nothing to buy.

Check yourself

Child correctly sorts a week of kitchen waste, explains what compost is for, and describes what happened to the buried leaf versus the wrapper.
