Introducing kids to composting: an eco-friendly learning game

Why introduce kids to composting?

Composting offers many educational benefits:

• Understanding natural cycles: Kids see first-hand how waste turns into a valuable resource

• Developing environmental responsibility: They take an active part in reducing the family's waste

• Exploring with all their senses: Touching, smelling and watching matter transform

• Connecting science and everyday life: Composting makes concepts like decomposition and the nutrient cycle tangible

• Building lasting habits: Habits learned in childhood take deep root

Where to start?

1. Choose the right composting system

Families have several options, depending on their space and lifestyle:

The classic outdoor bin is ideal for anyone with a yard. Kids can easily watch the process and take part in every step.

The worm composter is perfect for apartments. This compact system particularly fascinates kids, thanks to the worms hard at work turning waste into compost. It's a set of stacked trays where composting worms (Eisenia fetida) turn organic waste into rich compost and a fertilizing liquid called “compost tea.” You can get one at specialty garden centres, sustainable living stores or online. Several models exist, from the simplest plastic ones to designer wooden versions that blend right into a home's interior.

Bokashi is an interesting alternative for small spaces, using anaerobic fermentation that will intrigue budding young scientists. This Japanese system uses a microbial activator (fermented wheat bran) that you sprinkle over the waste in a special airtight bucket. The process produces a fermented liquid that can be used as fertilizer and pre-composted matter that can be buried in the garden or added to a traditional composter. Bokashi kits are available in zero-waste shops, some garden centres or online, and generally include the bucket, a tap to collect the liquid and the microbial activator.

2. Create kid-friendly tools

To make it easier for kids to take part, a few simple adjustments make all the difference:

• A small colourful bucket in the kitchen, just for the kids, to collect compostable scraps

• Kid-sized garden tools for turning the compost

• A magnifying glass to watch the little critters that help with decomposition

• An illustrated logbook to jot down observations

Making learning playful

Discovering the compost residents

One especially fascinating activity is discovering the different organisms that live in compost. Each creature has a specific role in the decomposition process:

• Primary decomposers like woodlice and millipedes that break the waste into smaller pieces

• Composting worms (Eisenia fetida) that digest the organic matter

• Microorganisms like bacteria and fungi that finish the decomposition

Encourage your kids to look up these organisms online to learn more about their biology and ecological role. Together, create an “identification guide” to the compost residents, with photos and descriptions. This exploration is a perfect blend of direct observation of nature and digital learning.

The apprentice composters game

Turn the composting routine into a family game:

1. The compostable treasure hunt: Who can find the most compostable items in the kitchen after the meal?

2. The compost detective: Observe and identify the organisms at work in the compost

3. The decomposition stopwatch: Predict which scrap will break down the fastest, and check back over time

Teaching by example

Children learn mainly by imitation. Build these practices into your daily life:

• Say your choices out loud: “This banana peel is going to feed our compost!”

• Show your enthusiasm as you discover the changes in the compost

• Use the finished compost on your plants or in your garden, explaining its role

Getting past the hesitations

Some kids (and parents!) may be reluctant about composting:

Fear of smells: A well-managed compost doesn't smell bad. Explain that bad smells are a signal that something needs adjusting.

Disgust at “critters”: Present the compost organisms as a team of “superheroes” who help us recycle. Start by watching from a distance before gradually getting closer.

Worry about getting dirty: Provide suitable gloves and a water source nearby for washing hands.

How to use your compost

Once the composting process is well along, it's time to reap the rewards of this patient family project and teach kids how to use this precious resource:

In the vegetable garden

• Soil amendment: Work the finished compost into the top few centimetres of soil before planting your vegetables. Kids can take part by using small shovels or their gloved hands.

• Educational planting: Set up two identical planting areas with your kids, one with compost and one without. Watch together for the difference in plant growth to show how effective compost is.

• Soil protection: Show your kids how to use compost as mulch around plants to hold in moisture and limit weeds.

For houseplants

• Enriched repotting: When repotting houseplants, let the kids mix the compost into the potting soil in the right proportions (about 1/3 compost to 2/3 potting soil).

• Compost tea: If you have a worm composter, collect with your kids the precious liquid (called “compost tea”) that drains out. Show them how to dilute it (1 part tea to 10 parts water) before feeding your plants.

Special projects

• Growing seedlings: Use your compost mixed with potting soil to start seedlings on a windowsill. Kids can then follow the whole cycle, from kitchen scraps to a new plant.

• A gift that grows: Help your kids prepare small pots with compost and seeds to give to family or friends – an eco-friendly and educational gift.

• Science experiments: Compare the growth of identical plants in different media (soil only, pure compost, a soil-compost mix) to see the differences.

Harvesting and using the compost lets you close the loop in a concrete way and shows kids the tangible results of their efforts. It's also a chance to reinforce patience and care, which are essential in gardening as in life.

Small seeds for the future

By introducing your kids to composting, you're planting far more than organic waste: you're sowing values of respect for the environment, careful observation and responsibility. These lessons will stay with them throughout their lives, giving them concrete tools to become aware, active citizens in the face of environmental challenges.

Composting is often the first step toward other eco-friendly practices that children can discover gradually: gardening, waste reduction, responsible consumption... A wonderful family adventure that starts with a simple apple core!
