By Susan Conklin Thompson. "Elephants are wrinkly" - its a statement any young child might make due to a keen awareness of texture. Now you can indulge students impulses to touch everything with more than 170 hands-on activities. Each chapter uses an animals texture as a jumping-off point to explore an eclectic group of topics. For example, in "Porcupines Are Prickly," kids learn about prickly things in nature, discover ways animals defend themselves, and discuss sharp tools and their uses.
