Evaluate the claims, evidence, and reasoning that the complex interactions in ecosystems maintain relatively consistent numbers and types of organisms in stable conditions, but changing conditions may result in a new ecosystem.
Clarification statement: Examples of changes in ecosystem conditions could include ecological succession, modest biological or physical changes, such as moderate hunting or seasonal floods; and extreme changes, such as volcanic eruption or sea level rise.
Performance Level Descriptions
PLDs communicate the knowledge and skills expected of students to demonstrate proficiency in each Learning Standard. NYS assessments classify student performance into one of five levels.
Use claims, evidence, and reasoning, to argue the merits of explanations regarding complex interactions in ecosystems and their ability to maintain relatively consistent numbers and types of organisms in stable conditions but changing conditions may result in a new ecosystem.
Evaluate the claims, evidence, and reasoning that the complex interactions in ecosystems maintain relatively consistent numbers and types of organisms in stable conditions but changing conditions may result in a new ecosystem.
Evaluate a claim using evidence that the complex interactions in an ecosystem maintain relatively consistent numbers and types of organisms in stable conditions or that changing conditions may result in a new ecosystem.
Identify an evidence-based claim that the complex interactions in an ecosystem maintain relatively consistent numbers and types of organisms in stable conditions or that changing conditions may result in a new ecosystem or given evidence, from those provided, identify the claim that describes the complex interactions.
Identify the evidence, from those provided, that supports the claim that complex interactions in an ecosystem maintain relatively consistent numbers and/or types of organisms in stable conditions.
Resources
Examples and discussion of resources for the learning, teaching, and assessment of HS-LS2-6.
This section could be expanded upon. You can help out by adding to this section.
Assessment
What assessment of HS-LS2-6 might look like on a NY state exam.
NGSS Dimensions
Performance expectation HS-LS2-6 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 claims, evidence, and reasoning behind currently accepted explanations or solutions to determine the merits of arguments.
- Scientific Knowledge is Open to Revision in Light of New Evidence
- Scientific argumentation is a mode of logical discourse used to clarify the strength of relationships between ideas and evidence that may result in revision of an explanation.
Disciplinary Core Ideas
- LS2.C: Ecosystem Dynamics, Functioning, and Resilience
- A complex set of interactions within an ecosystem can keep its numbers and types of organisms relatively constant over long periods of time under stable conditions. If a modest biological or physical disturbance to an ecosystem occurs, it may return to its more or less original status (i.e., the ecosystem is resilient), as opposed to becoming a very different ecosystem. Extreme fluctuations in conditions or the size of any population, however, can challenge the functioning of ecosystems in terms of resources and habitat availability.
Crosscutting Concepts
- Stability and Change
- Much of science deals with constructing explanations of how things change and how they remain stable.
