VariablesIndependent Variable –
What I will change.
Dependent Variable –
What I will measure.
Control – What I will
keep the same.

HypothesisA hypothesis is a statement that describes a relationship between two or more variables that can be tested.

If the INDEPENDENT VARIABLE is CHANGED,
then SOMETHING HAPPENS to the DEPENDENT VARIABLE.
Example: If the height of the ramp is increased then there is an increase in the distance the car travels.

Summary:Write an overview of what was done and what happened. Refer to specific results e.g. the average distance was 43.9 cm

Analysis:Were the results expected? Write about why you think these results were obtained. Use your scientific knowledge and further scientific evidence to explain your results. Refer to specific results and tends in your tables, graphs and diagrams.

Evaluation:What were the variables in this experiment. Which variable was changed? Was the experiment a fair test?Comment on any possible errors in the experiment.In what way could the experiment be improved?

ConclusionRestate the hypothesis.
Did the results support or refute the
hypothesis?
How did the results show this?
