Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.
Clarification statement: Emphasis is on functions at the organism’s system level such as nutrient uptake, water delivery, immune response, and organism response to stimuli. An example of an interacting system could be an artery depending on the proper function of elastic tissue and smooth muscle to regulate and deliver the proper amount of blood within the circulatory system.
Assessment boundary: Assessment does not include interactions and functions at the molecular or chemical reaction level.
Assessment
What assessment of HS-LS1-2 might look like on a NY state exam.
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.
Resources
Examples and discussion of resources for the learning, teaching, and assessment of HS-LS1-2.
This section could be expanded upon. You can help out by adding to this section.
NGSS Dimensions
Performance expectation HS-LS1-2 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
- Developing and Using Models
- Develop and use a model based on evidence to illustrate the relationships between systems or between components of a system.
- LS1.A: Structure and Function
- Multicellular organisms have a hierarchical structural organization, in which any one system is made up of numerous parts, and is itself a component of the next level.
- (NYSED) Disease is a failure of homeostasis. Organisms have a variety of mechanisms to prevent and combat disease. Technological advances including vaccinations and antibiotics have contributed to the prevention and treatment of disease.
- 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.
