Reflecting Light
Notice that light is reflected from surfaces, and that shiny smooth surfaces reflect light best
Lesson
Set out your lesson
“Reflection means light bounces from a surface. Paper and a spoon both reflect light. Smooth shiny surfaces reflect in an orderly way that can preserve images. Rough surfaces scatter light in many directions. Shiny does not always mean more total reflection than a pale rough surface. Safety: Use an intact metal spoon only. No glass mirror is required. No lasers, torch-to-eye beams, mains lamps or Sun viewing. Stop: Stop after the spoon and paper comparison. Do not test water, glass fragments, bright beams or outdoor sunlight.”
Bring to the table
- Paper
- Pencil
- Clean unbroken stainless-steel spoon
- A sheet of plain white paper
Extra for the adult
Worked example. I write that the paper reflects room light into my eyes, even though it shows no clear face image. The spoon can form an image because its smoother surface reflects more regularly. The curved spoon may distort or invert it, so it is not a flat-mirror model.
Optional challenge. Explain why a rough white wall can look bright without showing a sharp image of your face.
What to notice. Keep the comparison sheet. Note help recognising images, drawing arrows or explaining reflection.

Check understanding
- Explain that light bounces off surfaces, which is called reflection
- Identify that smooth, shiny surfaces (mirrors, still water) reflect light best
- Give everyday examples of reflection: mirror, puddle, polished floor
“Can your child explain why they can see themselves in a mirror or a shiny spoon, and why a rough wall doesn't reflect light the same way?”
