Show transcript
Aspects of an investigation that can be changed and measured are known as variables
The independent variable is what is changed in an investigation
The dependent variable is what is observed / measured in an investigation
Variables that are kept the same each time are called control variables
In a fair test, only the variable being tested is changed so that it is clear that it made a difference to the results
