🌡️ Filtration and Boiling Plan Studio

The teacher gives just-in-time modeling on how to compare polluted and purified samples, control variables, label data tables, and record anomalies during filtration and boiling-point testing. Teams then draft a brief investigation plan that includes materials, sequence of steps, safety notes, repeated trials, a data table, and evidence criteria for deciding whether purification changed the sample. Students annotate where chemistry ideas about mixtures and purity will help interpret results.
