Recall and apply the equation density = mass divided by volume.

Recall and apply the equation density = mass divided by volume. Evidence lens: Use the data, graph feature, practical observation, or particle behaviour that proves the answer. 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, mass, volume, 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 2 is specific to recall and apply the equation density = mass divided by volume and does not reuse a generic explanation from a neighbouring objective.
