← MS-LS2-3
MS-LS2-2 →

Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.

Clarification statement: Emphasis is on recognizing patterns in data and making warranted inferences about shifts in populations due to changes in the ecosystem.

Performance Level Descriptions

Every Grade 8 Science Test question on MS-LS2-4 is written to match one of the performance level descriptions (PLDs) below.

Level 1: Identify an argument that describes how a change in a physical or biological component of an ecosystem will have an effect on a population. Spring 2026 Question 28, Spring 2026 Question 47, Spring 2025 Question 11, Spring 2024 Question 42
Level 2: Identify the empirical evidence that supports the argument that changes to physical or biological components of an ecosystem affect populations. Spring 2024 Question 47
Level 3: Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations. Spring 2025 Question 50
Level 4: Construct an argument, supported by empirical evidence, that supports the claim that human activities cause changes to physical and biological components of an ecosystem, which affect populations.
Notice: PLD levels!

NGSS Dimensions

Performance expectation MS-LS2-4 was developed using the following elements from the NRC document A Framework for K-12 Science Education:

Science and Engineering Practices
  • Engaging in Argument from Evidence
    • Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
Disciplinary Core Ideas
  • LS2.C: Ecosystem Dynamics, Functioning, and Resilience
    • Ecosystems are dynamic in nature; their characteristics can vary over time. Disruptions to any physical or biological component of an ecosystem can lead to shifts in all its populations.
Crosscutting Concepts
  • Stability and Change
    • Small changes in one part of a system might cause large changes in another part.
