Check 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
“If your child 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?”
