Title| Conducting an experiment to study the fitness level of students| Aim / Objective of the Study| To study the fitness level of students / To determine cardiovascular fitness by measuring a person’s pulse rate before and after a given period of vigorous exercise| Problem Statement| How does the fitness level of students affect the time taken for pulse rate to return to normal?| Hypothesis| The fitter the student, the shorter the recovery time| Variables| Manipulated variable: Students with different fitness levelsResponding variable: Time taken for pulse rate to return to normal (recovery time)Fixed variable: Gender and size of students, number of steps per minute, time for exercise| Material| -|
Apparatus| A bench of 30 cm in heightStopwatch|
Technique used| (The step test) Measure and record the time taken for the student’s pulse rate to return to normal|
