MAKE THE RELATIONSHIP VISIBLE

Observe the model

Your experiment starts with a prediction.

Set the controls above and run a trial. A diagram, exact quantities and an explanation will appear here.

EVIDENCE, SIDE BY SIDE

Your laboratory notebook

Keep up to 8 trials for this investigation. Compare two recorded observations with exactly one changed control. Writing is saved as participation evidence.

No trials yet. Start with the setup above.

A controlled comparison needs two observations with exactly one changed input.

TURN AN OBSERVATION INTO AN EXPLANATION

Test your reasoning

What makes two different pack sizes directly comparable?

Use at least 40 characters, a result from each trial and one model limitation. Your writing is not automatically graded.

Build your investigation evidence

  • ○ Two observed trials with one changed control
  • ○ Mechanism / reasoning check
  • ○ Written explanation of at least 40 characters

These practice markers recalculate when evidence changes. They are not an official grade or a claim of mastery.
