Title: Effect of Exercise on Pulse and Breathing Rate
Aim: To observe the effects of exercise on pulse and breathing rates
Materials/ Apparatus: Stopwatch
Introduction:
Procedure:
1. Perform the experiment in group of 3 persons.
2. Decide beforehand who will count the pulse rate; count the breathing rate and who will perform the exercise.
3. Record the breathing rate and the pulse rate of the individual at rest.
4. The individual will do 100 jumping jacks.
5. The individual will run a lap around the field.
6. Start the stopwatch immediately after the exercise is over.
7. Take the pulse and breathing rate every two minutes until both rates return to normal.
8. Record the results in a table.

Introduction Guidelines:
1. What is exercise?
2. What are the benefits of exercise?
3. What are the 4 types of exercise?
4. What is aerobic exercise? Give some examples.
Discussion Questions:
1. How great was the increase of the pulse and breathing rates?
2. Why did the pulse and breathing rates increase?
3. What is oxygen debt?
4. Why did it take so long for the rates to return to normal?
5. Compare the group results:
a. Which group had the lowest/ highest pulse and breathing rates before exercise?
b. Which group had the lowest/ highest pulse and breathing rates after exercise?
c. Which group had the fittest person?
