Structures are made up of parts arranged in a way that serve a certain purpose. This book looks at human-made structures, such as bridges, and natural structures, such as plants, animal bodies, mountains, caves, rock formations, and icebergs, the materials from which they are made, and their colors, shapes, and textures. It shows structures made by animals, such as beehives and bird nests. The book also compares natural structures to human-made structures, such as natural bridges and human-made bridges, a ladybug and cars shaped like beetles, a bird and an airplane, and giraffes and construction cranes. This wonderful book with amazing photos will encourage young readers to notice colors and shapes in nature and how they relate to the purpose of structures.
Young readers will love learning how different plants and animals move. Sunflowers turn their heads to face sunlight, some plants close their flowers at night, and others move their heads to trap insects. Animals also move in many ways. Animals with limbs walk, run, hop, leap, climb, dance, and crawl. Animals with wings fly, flap, soar, and glide. Animals that live in water swim, hover, dive, leap, porpoise, and breach. Young readers will become aware of the different ways in which plants and animals move, as well as learn new vocabulary about movement through questions and activities.
