Heart Rate Lab (Part 2)
Now that you have completed part one of this heart rate lab, where you tested the effect
of 1 minute of jumping jacks on your heart rate, you will now design and conduct your
own heart rate lab. Go ahead and fill out the blue template I created below. A few
reminders to help you.
• Independent variable is what you are testing. In part 1 of this lab, it was the 60
seconds of jumping jacks. For you, it will be whatever you choose that might
affect your heart rate - maybe a different type of exercise, or an emotional
reaction, or placing your hand in icy water Anything you think will raise or
lower your heart rate.
• Dependent variable is what you are measuring to see if your independent
variable had any effect. For everyone, this will be the change in your heart rate.
. Your hypothesis is a testable prediction of how you think your independent
variable will affect your dependent variable.
• Procedure is what you will actually do. How long will you do it? What materials
do you need (probably a timer, on a cell phone or your chromebook)
• Data: make sure you record your resting heart rate BEFORE you conduct your
experiment! Follow the same procedure you followed in part 1.
• Conclusion is a reflection of whether your hypothesis was supported by your data
You can also include anything that went wrong, or what you would do differently
next time.
