How Earthworms Keep Our Soil Healthy

Next Generation Science

This educational video provides a comprehensive introduction to earthworms, exploring their biology, anatomy, and crucial role in the ecosystem. Hosted in the "Lighthouse Lab," the presenter begins by distinguishing between different types of worms—roundworms, flatworms, and segmented worms—before narrowing the focus to earthworms. Viewers learn about the physical characteristics of earthworms as invertebrates, specifically looking at their segmented bodies and the tiny bristles called setae that help them move through their environment.
