Research question: 2
Introduction to experiment: 2
Hypothesis: 2
Variables: 2 Independent variables: 2 Dependent variables: 2 Fixed (controlled) variables: 3
Apparatus to be used: 3
Method to be used to conduct experiment: 4 How the independent variable s going to be manipulated whilst the dependent variable is being measured. 4
Sample size: 4
Tables for girls 5
Tables for boys 6
Graphs: 7 Graphs for girls 8 Graphs for boys: 10
Discussion of results: 13 Individual graphs for each day of each sample: 13 The speeds for each sample: 13 The overall heart rates of all samples: 13

RESEARCH QUESTION:
How does the average heart rate of “sports” girls differ from that of non-sports girls?
HYPOTHESIS:
The average sports boy’s heart does not have to work as hard after and during exercise compared to that of a sports girl.
VARIABLES:
Independent Variables: * Shoes or no shoes * Gender * How often the sample does sport * If sample is naturally sporty * Height * Weight
DEPENDENT VARIABLES * Heart beats per second
FIXED (CONTROLLED VARIABLES) * Age * Sports person * Days temperature * Time heartbeat taken after activity * Type of grass and condition grass is in * 100m sprints (activity done) * Weather of each day * Direction of wind * Time taken to count heart beats * Time resting after exercise and before timing heart rate
Apparatus to be used:
Watch: Time 15 seconds after sprint; time heart beat for a minute
Stop watch: Time the speed at which the learners ran the 199m sprint
Field: 100m grass sports field for learners to run on
Learners: 5 boys and 5 girl learners
Additional: pen; paper; laptop
Method to be used to conduct experiment:
How the independent variables going to be manipulated whilst the dependent variable is being measured.
