Homeostasis and breathing investigation

Interactive science investigation on homeostasis - to keep an athlete running.

The body has automatic control systems that maintain your homeostasis.

In this investigation you need to maintain the runner's internal environment, regulating their oxygen, fluids, blood sugar and temperature.

Structure and features

Engage in this science investigation to change variables and observe examples of negative feedback when oxygen levels decrease in their bodies.

This learning object focuses on the interactions between the circulatory and respiratory systems.

On the completion of this science investigation students choose a drawing, flowchart or diagram to describe an analogy for homeostasis from their everyday life.

Write a scientific report on:

  • the variable you measured
  • the variable you changed
  • what variables you kept constant
  • your results and a discussion on your findings.

  • Homeostasis.

In this interactive lab, students don't need much background knowledge about the circulatory and respiratory system in order to understand how they relate to homeostasis and feedback loops.

Students learn that our body relies on coordination of the respiratory, circulatory, digestive, nervous and excretory systems to provide our requirements to function and respond to changes in the environment (for example oxygen, nutrients, water and removal of waste).

In this investigation, students record and analyse patterns in data, including describing relationships between variables.
