WA.4. Life Science
LS1. Structures and Functions of Living Organisms
K-1.LS1. Plant and Animal Parts: Students learn that all living things have basic needs, and they meet those needs in various ways. Just as humans have external body parts that perform different functions to meet their needs, animals and plants also have body parts that perform different functions to meet their needs. A magnifier is a tool that reveals further details of plant and animal parts that are not easily seen with the unaided eye. Learning about the diverse needs of plants and animals and the various ways they meet their needs will help to prepare students to understand more detailed structures beginning at the 2-3 grade band.
K-1.LS1B. Students know that all plants and animals have various external parts.
K-1.LS1B.1. Students are expected to identify the external parts of different plants and animals (e.g., legs on an insect, flowers, stems, and roots on many plants, feathers on birds, scales on fish, eyes and ears on many animals).
K-1.LS1C. Students know that the parts of a plant or animal appear different under a magnifier compared with the unaided eye.
K-1.LS1C.1. Students are expected to observe how parts of a plant or animal look under a magnifier and draw or use words to describe them (e.g., a single hair, the leg of an insect, a fingerprint).
K-1.LS1D. Students know that different animals use their body parts in different ways to see, hear, grasp objects, and move from place to place.
K-1.LS1D.1. Students are expected to compare how different animals use the same body parts for different purposes (e.g., humans use their tongues to taste, while snakes use their tongues to smell).
LS3. Biological Evolution
K-1.LS3. Classifying Plants and Animals: 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.
K-1.LS3C. Students know that external features of animals and plants are used to classify them into groups.
K-1.LS3C.1. Students are expected to describe several external features and behaviors of animals that can be used to classify them (e.g., size, color, shape of body parts).
K-1.LS3C.3. Students are expected to give examples to illustrate how pairs of plants and/or animals are similar to and different from each other (e.g., cats and dogs both have four legs, but many dogs have longer snouts than cats).
