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).
Structures and Functions of Living Organisms
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.
Different animals use their body parts in different ways to see, hear, grasp objects, and move from place to place.
