Lightbulb Lessons

Need an easy, no-prep physics lesson to leave for a substitute? “What Color Is That Star?” is a ready-to-use emergency sub plan or classroom enrichment activity where students explore the connection between color, wavelength, and star temperature! Students will think critically about light energy, analyze real-world star data, and design their own star system—all while reinforcing key physics concepts about the visible spectrum.
