LS1. Structures and Functions of Living Organisms
4-5.LS1. Structures and Behaviors: In prior years, students learned that all plants and animals have life cycles. In grades 4-5 students learn that plants and animals have different structures that work together to respond to various internal and external needs. Students compare various human and animal structures and reflect on how the different structures enable the organism to respond to external and internal needs. Students also learn that healthy body structures depend on good nutrition. These concepts are stepping-stones to later understanding of how structures are built up from cells.
4-5.LS1A. Students know that plants and animals can be sorted according to their structures and behaviors.
4-5.LS1A.1. Students are expected to sort plants and animals according to their structures (e.g., presence of hair, feathers, or scales on their skin) and behaviors (e.g., grazing, hunting, or diving for food).
