Book excerpt: It's a cool, damp night, and a wriggling worm searches for food in a garden. Before the sun rises, it returns to its home in the soil. Tiny hairs on the worm's skin grab the dirt to help the crawler move forward. As the worm squirms underground, its long body breaks up the soil and creates tunnels. Welcome to the worm's hole! Clear text, colorful photos, and diagrams will engage young readers as they explore the habitat, physical characteristics, diet, and behavior of these curious creatures. Age-appropriate activities and critical-thinking questions give readers an opportunity to make observations and gain valuable insights.
