A brightly colored spider stretches silky threads between two tree branches. Then it lets more silk out of its body and moves back and forth to make a set of straight lines. Finally, the spider moves in a spiral path leading out from the center of its large, wheel-shaped home. Welcome to the spider's web! 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.
