Title of experiment: Pulse count
Aim:
To study how biological actions respond to pulse count.
Problem statement:
Does the pulse count increase when we perform a heavy task?
Hypothesis:
_______________________________________________________________________
Materials:
None
Apparatus:
Stopwatch
Variables:
Manipulated variable:______________________________________________________
Responding variable:_______________________________________________________
Constant variable:_________________________________________________________
Procedure:
1. Each student should count their pulse for 1 minute upon waking up, prior to exercise, right
after doing exercise and 15 minutes after doing exercise.
2. Record all the students’ pulse counts in a table.
3. Calculate the average pulse count for each activity.
4. Plot a graph of type of activity against average pulse count.
Procedure: (Convert to past tense and passive sentence form)

*Students are required to plot a graph of type of activity against average pulse count on a
graph paper.
