Book excerpt: Students will learn all about intriguing adaptations that help animals survive in their environments, such as what playing a video game can teach us about striped lizards, the power of the chameleon’s sticky tongue, how wriggling and slashing saves frog eggs, a good partnership between sweet plants and ants, and the secret of the swordfish’s slippery head. Primary sources include interviews with scientists and original photos. Engaging yet simple language makes complicated scientific principles easy to grasp. A hands-on activity allows students to take on the role of scientist and examine these amazing adaptations themselves.
