Apply MS 1c and MS 3c skills when using standard form, significant figures and rearranging the density equation.

Apply MS 1c and MS 3c skills when using standard form, significant figures and rearranging the density equation. Boundary lens: Keep this separate from nearby specification points that use similar words but test a different idea. In Density of materials, this means density links mass and volume, so the answer must preserve which quantity is being calculated. The answer should use the approved wording from Changes of state and the particle model, include density, and avoid drifting into another section of Particle model of matter. For revision, practise saying the exact objective aloud, then add the one calculation, particle movement, collision, graph, or practical detail that makes the statement true. A strong exam response for checkpoint 15 is specific to apply MS 1c and MS 3c skills when using standard form, significant figures and rearranging the density equation and does not reuse a generic explanation from a neighbouring objective.
