2-LS2-2 Ecosystems: Interactions, Energy, and Dynamics
Students who demonstrate understanding can: Develop a simple model that mimics the function of an animal in dispersing seeds or pollinating plants.*
Clarification Statement: Examples include: placing socks on the outside of students’ shoes and walking outside allows socks to gather seeds; plant sock(s) to see what grows; using an eyedropper to move liquids from one container to another emulating hummingbirds or bees pollinating plants.
Assessment Boundary: N/A
Crosscutting Concepts	Science & Engineering Practices	Disciplinary Core Ideas
Structure and Function: The shape and stability of structures of natural and designed objects are related to their function(s).	Developing and using models: Modeling in K–2 builds on prior experiences and progresses to include using and developing models (i.e., diagram, drawing, physical replica, diorama, dramatization, storyboard) that represent concrete events or design solutions. Develop a simple model based on evidence to represent a proposed object or tool.	Interdependent Relationships in Ecosystems: Plants depend on animals for pollination or to move their seeds around. Developing Possible Solutions: (secondary to 2-LS2-2) Designs can be conveyed through sketches, drawings, or physical models. These representations are useful in communicating ideas for a problem’s solutions to other people.
