Marl and the Worm Bin: A Vermicomposting Adventure

By Jacqueline Cooper

Marl and the Worm Bin: A Vermicomposting Adventure is a curiosity-filled picture book set inside a working compost bin, where a young worm named Marl begins to wonder where the food in his world comes from.

Born in the darkness of the bin, Marl and his friend Squish wriggle upward through layers of soil, cardboard, peels, and scraps to discover how fresh food arrives. Along the way, they meet other worms, feel the bin tremble, and watch in awe as bright kitchen scraps rain down from above.

This engaging story gently introduces children to vermicomposting, composting worms, and the hidden ecosystem inside a worm bin. Their adventure naturally explores curiosity, teamwork, and how even tiny creatures help care for the earth.

Perfect for:

- Parents looking for meaningful, science-adjacent picture books

- Homeschool families studying nature or environmental science

- Classrooms and school libraries exploring composting and sustainability

- Garden centers and eco-conscious gift shops

- Earth Day and spring gardening themes

Includes an educational back matter section about vermicomposting, composting worms around the world, what worms eat, and why worm castings matter.

This deluxe hardcover edition is designed as a keepsake-quality book, ideal for gift giving, classroom collections, and public library shelves. With richly textured mixed media illustrations and a calm, classic layout, it is a story that can be revisited season after season.

A thoughtful blend of storytelling and real-world science, Marl and the Worm Bin celebrates compost heroes and the small creatures that make a big difference.
