This story follows Dusty, an adventurous boy who loves the outdoors, and his friend Daisy, a sweet girl with a large imagination, about soil and composting. They discover more about dirt as their teacher Mr. James gives them a greater understanding of soil, ecosystems, biomes, food webs, and sustainable living. With each chapter, readers are given challenges (experiments and activities) to dig deeper into each subject. Perfect for those who are naturally curious - teachers and students alike.
