Lab Member & Self Evaluation Survey
Day 1: Get into groups to form a QUESTION & HYPOTHESIS about how a specific activity (that you choose) impacts the autonomic nervous system by measuring heart rate. Create an EXPERIMENTAL PROCEDURE that will administer the same stimulus/activity that every group member will do and measure heart rate before and after the stimulus/activity. Determine the materials needed.
Day 2-3: In class, conduct the experiment by following established procedures and by using the materials brought by group members. GATHER DATA from multiple trials and from each team member. Analyze data and determine a CONCLUSION. Start creating the POSTER which will be used as part of a PRESENTATION of your experiment and results.
Day 4: Class presentation of experiment and results. Half of the groups will present in a type of gallery walk and assess other experiments and posters. Afterwards, groups will switch roles.
Grading: This lab will be graded based on the quality of the final poster and presentation of experiment. This lab is worth 100 lab points which can have an impact of up to 4-5% of your overall grade
For this activity, your group will design an experiment to test how a stimulus or activity activates the divisions of the autonomic nervous system by measuring your heart rate. You first need to learn how to measure heart rate accurately. During the next laboratory period, you will carry out your experiment, analyze your data, and prepare a short presentation describing your experiment.
- What is the autonomic nervous system and what does it control?
- What is the parasympathetic division of the autonomic nervous system? What does “rest and digest” mean?
- What is the sympathetic division of the autonomic nervous system? What does “flight or flight” mean?
- List 5 activities or stimuli that you think may increase a person’s heart rate. An activity is something a person does, and a stimulus is an input from the environment around a person.
- Why would it be useful for the heart to beat faster during these activities or in response to these stimuli?
- Are there any activities or stimuli that you think may decrease a person’s heart rate?
Part 1: Planning of experiment
Write your plan on a separate piece of paper!
- What is your hypothesis?
- Plan your experimental procedure. You should keep everything in your experiment the same except for the one variable that you are testing. When you write down your procedures, remember that the heart rate can be affected by even minor physical activity like changing seats, so you need to keep this in mind when planning to test the effect of your stimulus or activity. Plan to have each person in the group be a subject in the experiment, in order to see whether different people have the same heart rate response to your stimulus or activity.
- Write down the procedure for your experiment. Include:
- What you plan to do to your subjects
- What the activity is
- When you will measure heart rate
- How often you will measure heart rate (e.g., 2 or 3 times before the activity, during the activity, after the activity)
- Names of each student in the group
- Resting heart rates for each subject before the stimulus or activity
- The heart rates during and/or after the stimulus or activity
- Anything you notice which might affect the results (e.g., other things which may be happening in the room during your experiment or changes in each subject’s mood during the experiment)
- Calculations for the difference between resting heart rate and the heart rate during stimulus or activity.
- Calculations for the average change in heart rate for all subjects in the experiment.
Write results on a separate piece of paper!
- Review your experimental plan from last class period.
- Carry out the experiment for each subject in your group (see 3 above).
- Record your data in your data table (see 4 above).
- Do your calculations (see 4e and 4f above).
- Do your results support your hypothesis? What conclusions can you draw from your experiment.
