Controlling variables (age 11+)
Form a testable scientific hypothesis linking an independent variable to a predicted outcome, plan a full investigation identifying independent, dependent, and control variables, sample size, and risk assessment
Suggested ages 11–12
Evidence of understanding
- Writes a hypothesis in the form 'I predict that [IV] will affect [DV] because...' supported by scientific reasoning
- Identifies and labels the independent variable, dependent variable, and at least three control variables
- Plans repeat readings and an appropriate sample size, and identifies relevant hazards with control measures
Assessment prompt
If Controlling variables (age 11+) wanted to investigate whether temperature affects how quickly sugar dissolves, could they write a clear prediction, state exactly what they would change and measure, list three things to keep the same, and identify any safety steps?
