2015 Revision

This 2015 activity, "Homeostasis and Negative Feedback – Concepts and Breathing Experiments", is essentially a new activity with a minor overlap with the previous breathing activity. This 2015 activity includes:

  • an introduction to homeostasis and negative feedback
  • an experiment that demonstrates the effects of negative feedback on rate and depth of breathing
  • an added section in which students design and carry out an experiment to test a hypothesis concerning the effects of exercise on rate and depth of breathing.

This activity is aligned with the Next Generation Science Standards (see page 1 of the Teacher Preparation Notes).
