Teaching Kids About Composting: Turning Waste into Nutrients

Mar 20, 2024

Welcome to Kids Growing City, where we believe in fostering a love for nature and sustainability in our youngest generation! Today, we're thrilled to embark on a gardening adventure that's perfect for the whole family: composting! Let's delve into the world of decomposing organic matter and discover how it can enrich our lives and our gardens.

What is composting?

Composting is like nature's ultimate recycling program. It's the process of transforming kitchen scraps, yard waste, and other organic materials into nutrient-rich soil. Instead of tossing these items into the trash where they'll end up in a landfill, composting gives them a new purpose – nourishing our plants and enriching our soil.

But composting is more than just recycling. It's a fascinating glimpse into the intricate web of life that exists in our gardens. As organic matter breaks down, it creates a bustling ecosystem of microbes, worms, and other tiny creatures that work together to create healthy, vibrant soil.

But how do you explain this to your kids in a way that's both understandable and exciting? Here are a few simple tips:

  1. Make it Hands-On: Kids learn best through hands-on experiences. Take them outside and show them the different materials that can be composted, such as fruit and vegetable scraps, eggshells, coffee grounds, and yard trimmings. Let them touch and smell the compost to understand how it transforms over time.
  2. Explain the Process: Break down the composting process into simple steps that kids can understand. Start with the basics: decomposition. Explain how microorganisms like bacteria and fungi break down organic matter into smaller particles, eventually turning it into nutrient-rich compost.
  3. Connect it to Nature: Help kids make the connection between composting and the natural world around them. Talk about how composting mimics the way nutrients are recycled in nature, returning to the soil to nourish plants and support new growth.
  4. Get Creative: Encourage kids to get creative with their composting efforts. Let them decorate a compost bin or create a composting journal to track the progress of their organic waste as it transforms into compost. Turning composting into a fun and creative activity will keep kids engaged and excited to participate.
What are the benefits of composting?

The benefits of composting are as plentiful as the fruits of a well-tended garden! For starters, composting enriches the soil, providing essential nutrients that help plants grow strong and healthy. It also improves soil structure, making it more resilient to drought and erosion.

But the benefits don't stop there. Composting reduces the need for chemical fertilizers and pesticides, which can harm beneficial insects and pollute our waterways. It also helps to reduce greenhouse gas emissions by diverting organic waste from landfills, where it would otherwise release methane, a potent greenhouse gas.

How to Make a Compost Bin ideal for kids

Ready to take your composting adventures to the next level? In this guide, we'll show you how to create a kid-friendly compost bin right in your own backyard. With just a few simple materials and some creative flair, you can make composting fun and accessible for the whole family!

Materials Needed:
  • A large plastic storage bin with a lid

  • A drill with a 1/4-inch drill bit
  • Organic materials for composting (e.g., fruit and vegetable scraps, coffee grounds, eggshells)

  • Optional: Decorative stickers, paint, or markers for customization
Step-by-Step Guide:
  1. Prepare Your Bin: Start by selecting a large plastic storage bin with a tight-fitting lid. This will help keep pests out and odors in. Choose a bin that's the right size for your family's composting needs.
  2. Drill Holes: Using a drill with a 1/4-inch drill bit, carefully drill several holes in the sides and bottom of the bin. These holes will provide ventilation and drainage, allowing air to circulate and excess moisture to escape.
  3. Add Brown Materials:  Place a layer of brown organic materials, such as shredded newspaper or dried leaves at the bottom of the bin. 
  4. Add Green Materials: Place a layer of green organic materials, such as fruit and vegetable scraps, coffee grounds, and eggshells on top of the brown materials. Encourage your kids to help gather kitchen scraps and add them to the compost bin regularly.
  5. Mix and Water: Use a shovel or pitchfork to mix the compost materials together, ensuring that they are evenly distributed. Add a little bit of water to moisten the compost pile, but be careful not to make it too wet.
  6. Cover and Wait: Once your compost bin is set up, cover it with the lid and let nature do its magic! Over time, the organic materials will decompose and turn into nutrient-rich compost that you can use to fertilize your garden.
Customization Ideas:
  • Decorate the Bin: Get creative and let your kids decorate the compost bin with stickers, paint, or markers. Personalizing the bin will make it feel special and encourage your little ones to take ownership of their composting project.

  • Educational Labels: Create labels for the different types of compostable materials to help kids learn about recycling and environmental stewardship. You can also add fun facts about composting to spark their curiosity and imagination.


By involving your kids in the composting process, you're not only teaching them valuable lessons about sustainability and environmental stewardship but also fostering a deeper connection to the natural world. As they watch their food scraps transform into nutrient-rich soil, they'll gain a greater appreciation for the magic of nature and the importance of caring for our planet.

Remember, every small action we take to care for our planet makes a difference. Together, we can cultivate a love for nature and empower the next generation of environmental superheroes!
