You will build an H–R diagram from mystery-star data. You will test an early explanation through peer feedback.

You will turn H–R patterns and puzzling data into a focused investigation plan. You will test your method through source checks, peer feedback, and revision.

You will run three linked investigations with mathematical models and prepared datasets. You will keep traceable records. You will make early figures. You will track uncertainty. You will use peer feedback before a midpoint quality gate and reflection.

You will test your interpretations, revise your evidence, and prepare a trustworthy stellar story.

Rehearse your evidence story. Revise it. Lead a public stellar property tour. Stellar property means a star's feature, like brightness or temperature. Submit your report, figures, calculations, audience feedback, and final reflection.
