Construct an explanation based on evidence that describes how genetic variations of traits in a population increase some individuals’ probability of surviving and reproducing in a specific environment.
Clarification statement: Emphasis is on using simple probability statements and proportional reasoning to construct explanations.
Assessment
What assessment of MS-LS4-4 might look like on a NY state exam.
| Exam | Cluster | Question |
|---|---|---|
| Spring 2026 | Giraffe Adaptations and Population Changes | Question 44 |
| Spring 2024 | Respiration | Question 43 |
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 four levels.
☐
Level 1: Identify an explanation based on evidence that describes how a variation in a genetic trait in a given population may cause an increase in some individuals’ probability of surviving and/or reproducing.
☐
Level 2: Identify the evidence that supports the explanation that a variation in a genetic trait in a given population increases some individuals’ probability of surviving and/or reproducing in a specific environment.
☐
Level 3: Construct an explanation based on evidence that describes how genetic variations of traits in a population causes an increase in some individuals’ probability of surviving and reproducing in a specific environment.
☐
Level 4: Construct an explanation based on evidence that describes how genetic variations of traits in a population causes an increase in some individuals’ probability of surviving and reproducing in a specific environment, and explain why these traits would appear more frequently in future generations.
Resources
Examples and discussion of resources for the learning, teaching, and assessment of MS-LS4-4.
This section could be expanded upon. You can help out by adding to this section.
NGSS Dimensions
Performance expectation MS-LS4-4 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
- Construct an explanation that includes qualitative or quantitative relationships between variables that describe phenomena.
Disciplinary Core Ideas
- LS4.B: Natural Selection
- (NYSED) Natural selection can lead to an increase in the frequency of some traits and the decrease in the frequency of others.
Crosscutting Concepts
- Cause and Effect
- Phenomena may have more than one cause, and some cause and effect relationships in systems can only be described using probability.
