Keeping a Balance: Homeostasis & Negative Feedback

$12.95 – $83.95

Learn how negative feedback mechanisms maintain homeostasis.

How are negative feedback mechanisms used to maintain homeostasis?

  • Do a hands-on simulation to show how “Cupples” maintain homeostasis.
  • Use a graphic organizer to illustrate feedback control mechanisms for regulating body temperature.
  • Learn how blood glucose concentration is regulated.

HS-LS1-3. Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis.

  • Science & 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.A: Structure and Function - 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

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