WorksheetsInvestigating rate of breathing
Total questions: 10
Worksheet time: 6mins
What are we trying to find out when investigating rate of breathing?
The amount of oxygen in the air
The speed of our breathing
The total energy our body produced
The energy used up from physical activities
Which of the following instrument is needed to measure rate of breathing?
Clock or timer
Thermometer
Oximeter
What is the proper method when investigating rate of breathing?
Count the number of breath we take in two minutes
Count the number of breath we take in two hours
Measure the amount of oxygen we breathe in after one minute
Measure the amount of carbon dioxide we breathe out after one minute
Four students are investigating their rate of breathing. Why did they take 4 readings instead of only using 1 reading?
To check that everything is correct
To make the data more accurate
To calculate the average reading
Calculate the average reading for Aziqah.
(a)
Two of the students measure their breathing after doing physical activity. Which two students are they?
Ahmad
Ali
Afizah
Aziqah
How do you know the two students have physical activities before doing the experiment?
The have larger number
They breath in more in one minute than the other students
Their number of breath is lower than the other students
What does this experiment show?
Different people have different rate of breathing
Rate of breathing increases after doing physical activity
Male and female have different rate of breathing
Ali and Aziqah did some physical activity before doing the experiment.
One did some jogging, another did some running for 30 seconds.
Who did the running before the experiment?
Ali
Aziqah
How do we know Aziqah did the running?
Running increases rate of breathing as more air enter our lungs when running
Running is a heavier physical activity.
The heavier the physical activity the higher the rate of breathing
Running causes our heart to beat faster. This causes her rate of breathing to be higher as well
