No Prep Plans: Year 8 Physics – Dispersion of White Light Light Spectrum Display

No Prep Plans: Year 8 Physics – Dispersion of White Light
Light Spectrum Display | Grades 6–8
Help students discover that white light is made up of many different colours with this engaging, hands-on No Prep Plans investigation! Through research, guided observations, scientific diagrams, and a creative display project, students explore how dispersion occurs when light passes through a prism and why different colours bend by different amounts. Students finish the lesson by designing and explaining their own Light Spectrum Display, reinforcing key physics concepts through both scientific understanding and creativity.

Designed for Cambridge Lower Secondary Science, this ready-to-use lesson requires minimal preparation while promoting inquiry, observation, scientific communication, and critical thinking.
