3-LS4-4 Biological Unity and Diversity

Students who demonstrate understanding can: Make a claim about the merit of a solution to a problem caused when the environment changes and the types of plants and animals that live there may change.*  
Clarification Statement: Examples of environmental changes could include changes in land characteristics, water distribution, temperature, food, and other organisms.
Assessment Boundary: Assessment is limited to a single environmental change. Assessment does not include the greenhouse effect or climate change.

Crosscutting Concepts

Science & Engineering Practices 

Disciplinary Core Ideas 

Systems and System Models: 

  • A system can be described in terms of its components and their interactions.

 

 

Engaging in Argument from Evidence: 

  • Engaging in argument from evidence in 3–5 builds on K–2 experiences and progresses to critiquing the scientific explanations or solutions proposed by peers by citing relevant evidence about the natural and designed world(s).
  • Make a claim about the merit of a solution to a problem by citing relevant evidence about how it meets the criteria and constraints of the problem.

Ecosystem Dynamics, Functioning, and Resilience:

  • When the environment changes in ways that affect a place’s physical characteristics, temperature, or availability of resources, some organisms survive and reproduce, others move to new locations, yet others move into the transformed environment, and some die. (secondary to 3-LS4-4)

Biodiversity and Humans:

  • Populations live in a variety of habitats, and change in those habitats affects the organisms living there.
