This tongue twister, is also a good question. In this clear and engaging non-fiction nature book, kids will go on to answer it themselves, as they use observation and inquiry to distinguish how mammals are different from other animals. Earthworms are soft inside and out but mammals have body parts that are hard. Insects are hard on the outside, but mammals have their skeletons on the inside. Fish have skeletons inside, but get oxygen from the water, while mammals breather air into their lungs. This process of comparison builds along the evolutionary path of life on earth. A beautiful and informative book that introduces young children to animal classification and dichotomous inquiry ER -
