Experiment: Homeostasis
Exercise causes many factors of homeostasis to kick in to maintain internal equilibrium. How exercise affects some of these factors can be determined by measuring and observing certain conditions of the human body. Some of these conditions are:
• Breathing rate
• Heart rate
Working in groups of two or three, each student will undergo the following activity. Measurements will need to be taken three times for each student. Have a think about why we would need to repeat the experiment.
Procedure
1. In your groups, discuss what you predict will happen in this experiment (how will heart rate and breathing rate will be effected by exercise). This will be your hypothesis.
2. Make observations and measurements of the person's heart rate, and breathing rate per minute whilst they are resting. Each student should do this three times and you need to record your results in the Google Sheet on Moodle.
3. Student then needs to exercise (jumping jacks, running on the spot etc.) for 2 minutes. Then the group needs to make observations and measurements of the person's heart rate, and breathing rate per minute. Each student should do this three times and you need to record your results in the Google Sheet on Moodle.
4. Calculate the mean results for each student and construct two graphs (one for heart rate and one for breathing rate) showing your class results. (See video on Moodle on how to construct a graph on Google Sheets)
Presentation of Results - Scientific Report
Students will then be required to write a scientifreport which will be due on the day of their class in week 6. The scientific report should have an introduction, method, results, discussion and references and these make up the subheadings of your report. The report must follow scientific reporting conventions and be in past tense and third person (no personal language). The report should be between 500 to 600 words in length.
Introduction
In your introduction you must include:
• Background information about homeostasis (must include citations/references)
• Hypothesis
Methods
In your methods you must include details on how you did the experiment (be detailed, anyone should be able to repeat the experiment from your description). Remember it is an experiment you have completed so it needs to be in past tense.
Results
Your results section must include
• Two graphs showing class results for heart rate and breathing rate
• Description of your results (describe your graphs, are the results the same for all students? Are there differences?)
Discussion
Your discussion section must include
• Discussion on how the results relate to theory on homeostasis (must include citations/references)
• Any experimental errors/limitations in this experiment
• How could you improve the experiment
• Was your hypothesis correct
References
Your reference section should include at least two peer reviewed references (peer reviewed sources include journal articles and text books). References MUST be cited through your report.
