You will need a stopwatch or a watch that can act like a stopwatch.
1.Choose a person to help you with this experiment.
2.Tell the person to count the times he or she inhale air say that you will say 'GO' when he or she have to start.
3.Say 'GO' at the same time you start the stopwatch.
4.Say 'STOP' after 1 minute or 60 secinds.
This will be the breathing rate.You should normally get from12 to 20 breaths per minute.
5.Record your findings

When is your breathing likely to slow down?
when your heart rate slows down
What is the difference between displacement and speed?
Displacement is a measure of distance. Speed is a measure of the RATE at which the distance is traversed.
How do you find the deceleration rate?
The same as the acceleration rate. Measure the speed at one moment of time, measure the speed at another moment of time, calculate the difference, divide by the time elapsed.
What is the relationship between heartbeat and breathing rate?
Ideally the heart beats 3 to 4 times per breath.
What is the breathing rate of a human being while climbing stairs?
Increased - how much depends on speed & condition of climber.
What is your breathing rate measure after walking?
25-35
What is the name of instrument which measure the breathing rate?
Spirograph
What way can you measure respiration per minute?
rate of breathing how many breaths per minute
How are your breathing rate and pulse rate related?
The breathing rate and pulse rate are related proportionally. If the breathing rate increases, so does the pulse rate. The pulse rate is an indication of the breathing rate.
How does Ph regulate breathing?
It doesn't. pH is a measure of acidity or alkalinity of a substance, breathing is taking oxygen out of air and putting out carbon dioxide.
What other process could you have measured to determine to external and internal effects of exercise on the body?
Externally, you can measure perspiration. Internally, you can measure heart rate, breathing rate, and blood pressure.
What does rate of breathing indicate?
what does rate breathing indicate
If the breathing rate of males different from that of females?
breathing rate is nothing but loose it means
If the breathing rate of male is different from that females?
breathing rate is nothing but loose it means
When constructing a graph using breathing rates to temperature what are their variables in a graph?
The independent variable is the temperature. The dependent variable will be some measure of breathing rate - probably number if inspirations per minute.
What is a hypothesis for this science fair question what effect does exercise have on your breathing rate?
If I exersize it will increase/decrease my breathing rate because....(why you think it will increase or decrease your breathing rate)
What do you think is the relationship between breathing rate and heart rate?
The breathing rate is curve while the heary beat rate is straight(diagonaly)....
