Scientific Inquiry

Valid methods isolate the intended relationship; reliable measurements show consistency; uncertainty limits precision.

What to remember

  • Control relevant variables.
  • Repeat trials to assess consistency.
  • Use suitable measurement ranges.
  • Record units and uncertainty when appropriate.
  • Improve methods to reduce avoidable variation.

Key words

validity — testing intended relationship
reliability — consistency
uncertainty — limit on precision
variable — factor that can change
repeat — additional measurement/trial
How to use this drill: review the short notes when learning, then close them on later attempts and practise from memory. The rotating bank delays a full set repeat for 25 attempts on the same browser.

What this Year 8 / Grade 8 science drill practises
