Title: 2-LS2 Ecosystems: Interactions, Energy, and Dynamics

Performance Expectation: Plan and conduct an investigation to determine if plants need sunlight and water to grow. [Assessment Boundary: Assessment is limited to testing one variable at a time.]

Disciplinary Core Idea(s):
LS2.A: Interdependent Relationships in Ecosystems Plants depend on water and light to grow.

Science & Engineering Practices: Planning and Carrying Out Investigations Plan and conduct an investigation collaboratively to produce data to serve as the basis for evidence to answer a question.

Crosscutting Concepts: Cause and Effect Events have causes that generate observable patterns.

California Environmental Principles and Concepts:
Principle II The long-term functioning and health of terrestrial, freshwater, coastal, and marine ecosystems are influenced by their relationships with human societies. Principle V Decisions affecting resources and natural systems are based on a wide range of considerations and decision-making processes.

California Common Core State Standards Connections:
ELA/Literacy W.2.7: Participate in shared research and writing projects (e.g., read a number of books on a single topic to produce a report; record science observations). W.2.8: Recall information from experiences or gather information from provided sources to answer a question. Mathematics MP.2: Reason abstractly and quantitatively. MP.4: Model with mathematics. MP.5: Use appropriate tools strategically.

DCI Connections:
Connections to other DCIs in second grade: N/A Articulation across grade-levels: K.LS1.C; K-ESS3.A; 5.LS1.C
