🧊 Mystery Crystal Demo
Critical Thinking & Problem Solving
Submission Required
Students observe two pre-prepared sugar solutions: one cooled slowly and one rapidly, plus a supersaturated solution that begins crystallizing when seeded. They record detailed observations about crystal size, formation rate, and solution clarity in their lab notebooks. The class discusses why crystals formed differently and how this mirrors mineral formation in nature.
