Discussion prompts

  • Predict first: if liquid A is denser than B, which one moves underneath while they remain separated?
  • What two comparisons are needed to locate an object between two liquid densities?
  • Why does shaking help corn syrup dissolve into water while oil can separate again?

Where it shows up in real life

  • Oil separating to the top of salad dressing
  • Carefully poured layered drinks viewed before their bands blend
  • Oil spreading across water rather than sinking beneath it
