What is the main purpose of identifying control variables in a fair test investigation?
What is the main purpose of identifying control variables in a fair test investigation?
- To isolate the effects of the independent variable. (correct)
- To determine the accuracy of the measurement tools used.

Flashcards
Fair Test
Fair Test
A scientific investigation where only one factor (independent variable) is changed at a time, while all other factors (control variables) are kept constant to isolate the effect of the independent variable on the dependent variable.
Independent Variable
Independent Variable
The factor that is deliberately changed by the investigator in a scientific experiment.
Dependent Variable
Dependent Variable
The factor that is measured and observed in a scientific experiment to determine the effect of the independent variable.

Study Notes
Scientific Enquiry Types
- Five main types exist.
Planning Fair Tests
- Plan investigations with clear identification of:
- Independent variable (what you change)
- Dependent variable (what you measure)
- Control variables (what you keep the same).
Safety in Practical Work
- Follow safety procedures throughout experiments.
Basic Measurements and Recording
- Take accurate measurements.
- Record measurements properly.
