Systems and System Models
Knowledge
Students know:
- Biological hierarchy (cells, tissues, organs, organ systems, organisms).
- Specialized cells make up specialized tissues; specialized tissues make up organs (e.g., the heart contains muscle, connective, and epithelial tissues that allow the heart to receive and pump blood).
- Major organs of the body systems (e.g., circulatory, digestive, respiratory, muscular, skeletal, nervous).
- Functions of the body systems.
- Interacting organ systems are involved in performing specific body functions.
Skills
Students are able to:
- Construct a model or representation that demonstrates how interacting organs and systems accomplish functions.
- Describe the relationships between components of the model.
- Use observations from the model to provide causal accounts for events and make predictions for events by constructing explanations.
Understanding
Students understand that:
- The body is a system of multiple interacting subsystems (organ systems).
- Different organs work together to form organ systems that carry out complex functions (e.g., the heart and blood vessels work together as the circulatory system).
- The interaction of organ systems are needed for survival, growth, and development of an organism.
