HS-ESS3-4

← HS-ESS3-3

HS-ESS3-6 →

Evaluate or refine a technological solution that reduces impacts of human activities on natural systems.

Clarification statement: Examples of data on the impacts of human activities could include the quantities and types of pollutants released, changes to biomass and species diversity, or areal changes in land surface use (such as for urban development, agriculture and livestock, or surface mining). Examples for limiting future impacts could range from local efforts (such as reducing, reusing, and recycling resources) to large-scale geoengineering design solutions (such as altering global temperatures by making large changes to the atmosphere or ocean).

Performance Level Descriptions

Every Regents exam question on HS-ESS3-4 is written to match one of the performance level descriptions (PLDs) below.

Level 1: Given a technological solution, identify the natural system that is being impacted by human activity or identify how the solution reduces the impact on a natural system. August 2025 Question 8

Level 2: Given a technological solution to a geoscience problem, identify how the solution reduces impacts of human activities on the natural system or identify how the solution reduces the impact on humans. August 2026 Question 22

Level 3: Given a technological solution, describe the geoscience problem being addressed and how the solution reduces the impact of human activities on a natural system. June 2025 Question 50

Level 4: Evaluate or refine a technological solution that reduces impacts of human activities on natural systems. June 2026 Question 13

Level 5: Use scientific information to generate a number of possible refinements to a technological solution. Describe and quantify the criteria, constraints, and tradeoffs of the solution to the problem that reduces impacts of human activities on natural systems.

NGSS Dimensions

Performance expectation HS-ESS3-4 was developed using the following elements from the NRC document A Framework for K-12 Science Education:

Science and Engineering Practices

• Constructing explanations and designing solutions: Design or refine a solution to a complex real-world problem, based on scientific knowledge, student-generated sources of evidence, prioritized criteria, and tradeoff considerations.

Disciplinary Core Ideas

• Human impacts on Earth systems: Scientists and engineers can make major contributions by developing technologies that produce less pollution and waste and that preclude ecosystem degradation.
• Developing possible solutions: When evaluating solutions, it is important to take into account a range of constraints, including cost, safety, reliability, and aesthetics, and to consider social, cultural, and environmental impacts.

Crosscutting Concepts

• Stability and change: Feedback (negative or positive) can stabilize or destabilize a system.
• Influence of Engineering, Technology, and Science on Society and the Natural World: Engineers continuously modify these systems to increase benefits while decreasing costs and risks.
