Introducing children to vermicomposting: a fun and educational activity

Vermicomposting is a simple and enjoyable activity — even more so for children than for adults. Watching worms turn peelings into fertiliser has something fascinating about it at that age, and it is an ideal opportunity to raise their awareness of ecology through example rather than theory.

A gateway to ecology and science

A wormery is a small living ecosystem, visible and easy to understand: children can see for themselves what happens to kitchen waste, why some foods break down faster than others, and how a worm colony grows over the months. It is a natural way to approach recycling, the cycle of organic matter and caring for a living creature, and far more meaningful than an abstract explanation.

An educational tool loved by schools: the Willy soft toy

Child presenting the Willy soft toy to their classMany schools order our Willy soft toy to use as a genuine teaching tool: each day, the soft toy goes home with a different family, and the child looking after it has to come up with a simple action to put in place at home for the environment. The next day, they share it with the class, and another child takes Willy home to suggest their own idea in turn — a lovely little group ritual that runs all year round.

A few examples of everyday actions to suggest to children: turning off the tap while brushing your teeth, choosing a short shower over a bath, switching off the light when leaving a room, unplugging devices on standby, sorting your waste (recyclables, but also scraps for the wormery!), not throwing away unfinished food, walking or cycling to school when possible, repairing or giving away a toy rather than throwing it out, or picking up a bit of litter found outdoors during a walk.

Simple tasks to entrust to them

Turning this into a small regular ritual — always on the same day, for example — also helps to avoid overfeeding the wormery out of enthusiasm.

Adapt their involvement to their age: the youngest can simply watch while you handle the worms; older children can gradually sort the waste themselves, weigh it or chop it into small pieces, or even keep a little logbook (amount of waste, date of the last harvest) to make it a real little project.

Willy's tip

A few simple rules with younger children: we watch and handle gently, without squeezing the worms, we never put them in our mouths, and we wash our hands after every handling.

An experiment to observe together

To take things further, you can show them in a very visual way how worms work the soil: fill a clear jar with alternating layers of light and dark soil (or sand), place a few worms on top with a little food, cover with a dark cloth to respect their sensitivity to light, and observe every day. Within a few days, the layers gradually mix together as the worms move around — a hands-on way to see the work they usually do right under our noses, invisible in a tray wormery.

Curiosity that goes beyond the worms

A wormery is also home to other small creatures besides worms (springtails, mites, millipedes...) — completely harmless and rather fascinating to observe up close. This is often a chance to answer children's questions about what they see wriggling in the compost: our guide Life in a wormery introduces them one by one so you can answer with confidence.

In summary

Sorting waste together, watching the worms after each feed, or recreating their work in a simple jar: so many easy ways to introduce children to vermicomposting and make it a real family activity.
