How Science Works

Which variable is investigated and therefore changes for each set of repeats?

• Control

• Dependent

• Independent

• Hyper

If you didn't keep these the same then they would also affect the results and the test would be unfair.

• Dependent variable

• Control variables

• Independent variables

• Repeat variables

This variable will change in response to the variable that is changed in the investigation.

• Independent variable

• Dependent variable

• Control variables

• Infinite variables

Which variable goes on the x axis?

• Independent

• Dependent

• Control

Which variable goes on the y-axis?

• Independent

• Dependent

• Control

Which column does the independent variable go in?

• The first column

• The 2nd column

• The last column

• It doesn't matter

What is being described? This must start at 0, the spaces between marks equal and the number intervals equal.

• Column header

• Axis label

• Axis scale

• Hypothesis

What is being described? These must describe what the numbers in the cells refer to and if appropriate a unit of measurement in brackets.

• Axis label

• Axis scale

• Graph title

• Column header

What should your hypothesis do?

• Describe how the independent variable is likely to affect the dependent variable.

• Describe how the dependent variable is likely to affect the independent variable.

• Describe how the control variables are likely to affect the dependent variable.

• Describe how the independent variable is likely to affect the control variables.

What is the thing in the experiment that could potentially be harmful?

• Risk

• Hazard

• Precaution

• Hazard symbol
