Fair Test Variables Question Cards

About this printable

This printable contains twelve numbered question 'cards' (dashed cut lines) that ask pupils about independent, dependent and control variables, how to keep a test fair, what to measure, causes of unreliable results, and ways to improve or repeat investigations. Each card pairs a short question with a simple icon to support understanding and a short definition of a fair test is printed at the foot of the page. Use it to scaffold enquiry planning, formative assessment or to prompt discussion when students design or evaluate investigations.
