Product Highlights

  • To provide evidence of feedback mechanisms, students investigate human subject heart rates before and after exercise, and then plan and conduct an investigation of Daphnia heart rates.
  • High school laboratory investigation with enough materials for 8 lab groups.
  • Carolina Kits 3D™—Labs that use phenomena to support NGSS and 3-dimensional instruction.
  • Kit includes perishable materials for immediate use.

    Maintaining homeostasis is one of the most important functions that animals perform for their own survival. While animals maintain some processes through behavioral changes, many are handled through physiological changes such as changing heart rate, sweating, or muscle contractions. This 4-part lesson tackles homeostasis in animals. Students first examine their own heart rate, and then design an experiment to test external stimuli on Daphnia's cardiovascular system.

    Time Requirement
    Teacher prep, 30 minutes. Pre-lab, investigations, and assessment, approximately 4 class periods.

    Digital Resources
    Includes 1-year access to digital resources that support 3-dimensional instruction for NGSS. Digital resources may include a teacher manual and student guide, pre-lab activities and setup videos, phenomenon videos, simulations, and post-lab analysis and assessments.

    Learning Objectives

    • Understand that negative feedback is a homeostatic control mechanism that stabilizes the body’s internal environment.
    • Plan and conduct an investigation providing evidence that feedback mechanisms maintain homeostasis in animals.
    • Describe the relevant data to be collected and evidence to be derived from the data to measure a homeostatic response in a living system.
    • Assess the accuracy and precision of their data, as well as whether the data provide the evidence required to accept a hypothesis.

    Prerequisite Knowledge and Skills
    Students should feel comfortable with microscope usage, including adjusting the mechanical stage and manipulating the iris diaphragm to control specimen illumination. They should also have a basic understanding of experimental design.
