Investigating Pulse Rate
Plan:
I am doing an experiment to measure pulse rates. I am going to run at a prolonged pace for 30,60,90 and 120 seconds. I will then take a reading of my pulse. I will repeat my experiment to give a more accurate set of results. I will be taking results on myself and two other people, so that I can compare my level of fitness and heart rate to theirs.
Fair Test:
To make sure that my experiment is a fair one I need to keep some factors the same each time.
I need to make sure that I run for the specified amount of time, i.e. I don’t want to be running for 40 seconds and then actually I was only meant to run for 30. To make sure I don’t have any time related mishaps, I will use a stopwatch o keep track of times. I also need to make sure that I say at the same pace throughout my experiment. I intend to jog during my experiment rather than hard sprinting. I need to make sure that my pulse has calmed back down to normal pace before I proceed on to the next stage, because otherwise I wont get accurate results, as if I started from 60 beats per minute at the first stage, and then and 90 beats per minute at the second, I wouldn’t have a fair test. I also need to make sure that I take my pulse for the same amount of time, every time I take it. I am going to measure my pulse for 60 seconds, instead of 15 seconds and then multiplying the answer by 4.
