🎮 Where Does the Sample Settle?

📖 About this game

A game on the lesson of fluid behaviour, density and the Archimedes principle. Density is mass divided by volume, and a body denser than the fluid sinks to the bottom, one less dense floats, and one of equal density rests suspended at its level. Why the learner touches the place of the sample in the beaker rather than picking the word float or sink: the answer is a position, and whoever knows the position has seen the principle rather than its name. The content deliberately holds a heavy sample that floats and a light one that sinks: a learner who judges by mass alone without dividing by volume falls in exactly those two rounds, which is the expected mistake of this lesson. The sample is drawn at its own size, its side built from the cube root of its volume, and its position is computed from mass over volume against the density of water, so the drawing can never contradict the arithmetic. The division itself appears at the reveal as proof. Nine samples. No sign-up.

🕹️ How to play

1. Read the mass of the sample and its volume.
2. Divide the mass by the volume to get its density.
3. Compare it with the density of water, then touch its place in the beaker.
4. Every sample you get first try counts for you.
