Use logical rules to sort objects into two groups, those that are alive and those that are not.
Students learn that some objects are alive and others are not, and that many living things are classified as either plants or animals based on observable features and behaviors. Plants and animals are further classified into smaller groups such as insects and trees. Even these groups can be further subdivided. Classification provides a way to organize and find patterns in the amazing diversity of plants, animals, and the nonliving environment.
