Fair Test Variables Reference Poster

About this printable

This printable is an A4 reference poster that defines the three main types of variables, shows the six-step science enquiry process, gives concrete examples (e.g. sunlight and plant height) and provides a checklist for running a fair test. Use it as an instructional poster during experimental planning or as a quick reference students can consult while carrying out investigations. It emphasises changing only one independent variable, measuring the dependent variable consistently, keeping other variables the same, repeating trials and drawing conclusions.
