This document outlines the sections and contents of a homework project investigating the effect of exercise on breathing rate. The sections include an introduction explaining respiration and the human transport system, an aim to investigate how exercise affects breathing rate, a prediction and hypothesis about what effect will be observed, identification of independent, dependent, and controlled variables, a method, a table of results, a graph, an analysis of the results and trend seen in the graph, a conclusion drawing on results, and an evaluation of reliability and ways to improve the investigation.

1. Introduction
The purpose of my investigation is to…
Explain the science behind breathing and respiration
2. Aim
Your aim is to investigate the effect of exercise on breathing
rate – how will you do this?
3. Prediction and Hypothesis
What do you think the effect will be? What scientific
knowledge are you using to form this prediction? How can you
justify it? Reference!!!
4. Variables
What are your independent, dependent, and controlled
variables?
How will you do this?

10. Evaluation
From my graph it can be seen that ___ was the most reliable
as the range is only _____. The least reliable test
was________. The difference in reliability can be accounted
for by…
Anomalous results were identified in test ____. These could
have been caused by…
(Or) No anomalous results were identified in test. This is
because...
When I recognised an outlier I......
To improve my investigation, hence giving a more reliable
conclusion I would…
Problems I had
(method/technique and
equipment)
Solutions if I were
to this experiment
again
This would be
improvement
because....
