Variable Spotter is a free-to-try whiteboard game for identifying scientific variables. Each scenario shows a fair test in pictures; pupils drag the statement cards into the independent variable (what you change), the dependent variable (what you measure) and the control variables (what you keep the same) — and spot the red herrings that belong nowhere. A quick, hands-on way to build “working scientifically” skills, with no prep.
What are independent, dependent and control variables?
The independent variable is what you change, the dependent variable is what you measure, and control variables are what you keep the same so the test is fair. Variable Spotter has pupils sort statements into those three groups.
Is there a free-to-try activity for identifying variables?
Yes — Variable Spotter is a free-to-try whiteboard starter. Read the scenario, then drag each statement into change, measure or keep-the-same, watching out for the red herrings.
What ages and key stages is it for?
Three bands: Lower KS2 (ages 7–9, friendly words), Upper KS2 (ages 9–11), and Key Stage 3 (ages 11–14, formal terms and trickier red herrings).
Can I print a variables worksheet?
Yes — print a one-page worksheet of the scenario on screen to hand out or photocopy for the class.
