Next Generation Science Standards

Performance Expectations:

• HS-LS1-2. Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.
• HS-LS1-3. Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis. (Part 2 - note that it is the robot that is maintaining the homeostasis).

Disciplinary Core Ideas:

• 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.
  • Feedback mechanisms maintain a living system’s internal conditions within certain limits and mediate behaviors, allowing it to remain alive and functional even as external conditions change within some range. Feedback mechanisms can encourage (through positive feedback) or discourage (negative feedback) what is going on inside the living system.

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.
• Stability and Change
• Feedback (negative or positive) can stabilize or destabilize a system.

Science and Engineering Practices:

• Asking Questions and Defining Problems
• Developing and Using Models
• Planning and Carrying out Investigations
• Analyzing and Interpreting Data
• Using Mathematics and Computational Thinking
• Constructing Explanations and Designing Solutions
• Engaging in Argument from Evidence
