North America boasts a surprising number of rainforests, including El Yunque National Forest in Puerto Rico, Olympic National Forest in Washington State, Chugach and Tongass National Forests in Alaska, and the forests in Hawaii, which are home to an enormous variety of plants and animals. Rainforests: An Activity Guide takes kids through the common layers of the rainforest, from the forest floor to above the enclosed canopy. Their journey continues through the different types of rainforests as they are introduced to plants, animals, and people around the world, including those from the temperate rainforests of North America to the tropical rainforests of Southeast Asia, Africa, and South America. Rainforest-inspired activities include making a West African yam festival gourd rattle, building a model of an Alaskan totem pole, and creating a Japanese Wayang-kuilt, or shadow puppet. Kids are encouraged to make a difference and become active supporters of the rainforests no matter where they live.
