Light: Reflection, Refraction and Colour — Interactive Lesson (Ages 11–14)

Mirrors, rainbows, spectacles and stage lights all control light. This 18-slide interactive lesson on reflection and refraction takes pupils from first ideas to exam-style explanations, with 9 self-marking activities and nothing to prepare beforehand.

Teaching Light: Reflection, Refraction and Colour in KS3 Science

Pupils describe how light travels, use the law of reflection with the normal, and tell specular from diffuse reflection. They explain why light bends towards or away from the normal, how a convex lens focuses light, how a prism disperses white light into a spectrum, and predict the colour of objects seen through filters or under coloured light.

What Pupils Will Learn

• Describe how light travels.
• Use the law of reflection.
• Explain refraction and its effects.
• Describe how a convex lens focuses light.
• Explain dispersion, filters and the colour of objects.
