Keep each quantity with its units, scale, reference frame, sign convention, observation method, and uncertainty.
Separate direct observations from inferred properties. Record which model and assumptions connect the evidence to the conclusion.
Check sky maps, spectra, light curves, and diagrams for axes, legends, wavelengths, dates, orientation, and source details.
Use this review prompt: Which observation supports this model, and which alternative explanation must you exclude?
Use this review prompt: Which scale, unit, and reference frame make this value meaningful?
Analyse complete evidence separately. Short cards do not replace calculations, observing practice, graph interpretation, or model evaluation.
