Classification is the system we use to sort both living and nonliving things into groups. This clear and comprehensive account will help kids understand the many ways in which animals and plants, as well as nonliving things, can be classified. They will learn the scientific terms for classifying the animal kingdom into phylum, class, order, family, genus, and species. They will see how they themselves classify nonliving things on a day-to-day basis when they take part in a recycling program.
