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.LS1C. Students know that certain structures and behaviors enable plants and animals to respond to changes in their environment.
4-5.LS1C.1. Students are expected to give examples of how plants and animals respond to their environment (e.g., many plants grow toward the light, animals hide when they see a predator).
