From Molecules to Organisms: Structures and Processes

 

Students who demonstrate understanding can:

Performance Expectations
 

 

Develop models to describe that organisms have unique and diverse life cycles but all have in common birth, growth, reproduction, and death. 3-LS1-1

Clarification Statement and Assessment Boundary

Clarification Statement: Changes organisms go through during their life form a pattern.

Assessment Boundary: Assessment of plant life cycles is limited to those of flowering plants. Assessment does not include details of human reproduction.

Science and Engineering Practices

Developing and Using Models

Modeling in 3–5 builds on K–2 experiences and progresses to building and revising simple models and using models to represent events and design solutions.

Develop models to describe phenomena. (3-LS1-1)

Connections to Nature of Science

Science Knowledge Is Based on Empirical Evidence

Science findings are based on recognizing patterns. (3-LS1-1)

Disciplinary Core Ideas

LS1.B:  Growth and Development of Organisms

Reproduction is essential to the continued existence of every kind of organism. Plants and animals have unique and diverse life cycles. (3-LS1-1)

Crosscutting Concepts

Patterns

Patterns of change can be used to make predictions (3-LS1-1)
