You will be writing a procedure for the question: "How does different exercising activities change heartrate and breathing?" For your procedure, you need to consider: Which exercising activities are you going to compare? These are going to be your independent variables. I would choose two. Some options include: jumping jacks, lifting an object, going up stairs, running in place, push-up, sit-ups, doing a yoga pose. If you have any health considerations, please take these into account and do not hurt yourself. You are welcome to compare laying down and sitting for example.

How will you have a control to compare the exercise changes to? You might want to collect baseline resting data.

How are you going to collect data on heartrate and breathing? These will be your dependent variables. For heartrate, it's likely you can count your pulse for a minute or 30 seconds (or maybe you have a device that will do this?). For breathing, you may just need to note whether you feel like you are breathing harder. Another test is whether you can talk or not as you do the exercise.

How will you make sure it's a fair test? You might need to think about controls such as doing the activity for the same amount of time, switching which activity you do first, having time to rest between, have multiple repetitions, etc.
