← HS-LS4-4
HS-ESS2-6 →

Evaluate the evidence supporting claims that changes in environmental conditions may result in: (1) increases in the number of individuals of some species, (2) the emergence of new species over time, and (3) the extinction of other species.

Clarification statement: Emphasis is on determining cause and effect relationships for how changes to the environment such as deforestation, fishing, introduction of invasive species, application of fertilizers, drought, flood, and the rate of change of the environment affect distribution or disappearance of traits in species.

Performance Level Descriptions

Every Regents exam question on HS-LS4-5 is written to match one of the performance level descriptions (PLDs) below.

Level 1: Identify the evidence that supports that a change in an environmental condition may cause changes in species. August 2025 Question 44
Level 2: Identify a claim supported by evidence that a change in an environmental condition may cause changes in a species or justify if the provided evidence supports or does not support a claim that conditions may cause changes in species. June 2026 Question 43
Level 3: Explain how the provided evidence supports a claim that environmental conditions may cause a change in species such as (1) increases in the number of individuals, and/or (2) the emergence of new species over time, and/or (3) the extinction of species. August 2025 Question 2
Level 4: Evaluate the evidence supporting claims that changes in environmental conditions may result in: (1) increases in the number of individuals of some species, (2) the emergence of new species over time, and (3) the extinction of other species. August 2025 Question 5
Level 5: Evaluate the evidence and generate an argument defending/refuting a claim that changes in environmental conditions may cause situations which result in: (1) increases in the number of individuals of some species, (2) the emergence of new species over time, and (3) the extinction of other species.

NGSS Dimensions

Performance expectation HS-LS4-5 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
    • Evaluate the evidence behind currently accepted explanations or solutions to determine the merits of arguments.
Disciplinary Core Ideas
  • LS4.C: Adaptation
    • Changes in the physical environment, whether naturally occurring or human induced, have thus contributed to the expansion of some species, the emergence of new distict species as populations diverge under different conditions, and the decline – and sometimes the extinction – of some species.
    • Species become extinct because they can no longer survive and reproduce in their altered environment. If members cannot adjust to change that is too fast or drastic, the opportunity for the species' evolution is lost.
Crosscutting Concepts
  • Cause and Effect
    • Empirical evidence is required to differentiate between cause and correlation and make claims about specific causes and effects.
