Read the following experiment and state a good hypothesis. I am doing a test to see if there is a connection between how long you run and how fast your heart beats. I will be performing an experiment where a person will run for a 1 minute and I will check their heartbeat. Then they will run for 2 minutes and I will check their heart rate. I will do this up to 6 minutes and see if there is a connection. What do you think my hypothesis should be?
If I increase the amount of time I run, then my heartbeat will increase.
