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. This Resource Includes: Mini-Guide: Color and Temperature of S

Looking for a low-prep physics lesson to introduce or review lenses? “Through the Looking Glass” is a clear and engaging sub plan focused on the behavior of convex and concave lenses. Students will explore how these lenses affect light rays and apply that knowledge through visuals, real-world examples, and a critical thinking challenge. This resource helps students visualize how lenses bend light and is perfect for use during sub days or as reinforcement during a light and optics unit. ✅ T

Need a no-prep sub plan that reinforces core physics concepts? “Bending Light” is a ready-to-use lesson where students explore how light bends when it enters different materials, and apply Snell’s Law to analyze the behavior of waves. This activity challenges students to analyze data, complete calculations, and sketch ray diagrams — all with minimal prep. Perfect for sub days, reinforcement, or intro to light and optics units! ✅ This Resource Includes: Short scenario: Dr. Rayna’s Light Lab
