Use a model to illustrate cellular division (mitosis) and differentiation.
Clarification statement: Emphasis should be on the outcomes of mitotic division and cell differentiation on growth and development of complex organisms and possible implications for abnormal cell division (cancer) and stem cell research.
Assessment boundary: Assessment does not include specific gene control mechanisms or recalling the specific steps of mitosis.
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.
☐
Level 1: Use a model to identify one result of cellular division (mitosis) or differentiation.
☐
Level 2: Use a model to identify one result of cellular division (mitosis) and differentiation.
☐
Level 3: Use a model to describe the process of cellular division (mitosis) or differentiation.
☐
Level 4: Use a model to illustrate cellular division (mitosis) and differentiation.
☐
Level 5: Revise a model based on evidence to illustrate cellular division (mitosis) and differentiation.
Resources
Examples and discussion of resources for the learning, teaching, and assessment of HS-LS1-4.
This section could be expanded upon. You can help out by adding to this section.
Assessment
What assessment of HS-LS1-4 might look like on a NY state exam.
NGSS Dimensions
Performance expectation HS-LS1-4 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
Science and Engineering Practices
- Developing and Using Models
- Use a model based on evidence to illustrate the relationships between systems or between components of a system.
Disciplinary Core Ideas
- LS1.B: Growth and Development of Organisms
- In multicellular organisms individual cells grown and then divide via a process called mitosis, thereby allowing the organism to grow. The organism begins as a single cell (fertilized egg) that divides successfully to produce many cells, with each parent cell passing identical genetic material (two variants of each chromosome pair) to both daughter cells. Cellular division and differentiation produce and maintain a complex organism, composed of systems of tissues and organs that work together to meet the needs of the whole organism.
Crosscutting Concepts
- Systems and System Models
- Models (e.g., physical, mathematical, computer models) can be used to simulate systems and interactions - including energy, matter, and information flows – within and between systems at different scales.
