Making images

This unit explores the transmission of light, including absorption, scattering, and reflection, and the use of the ray model in imaging, refraction, and lenses. It also covers energy transfer in various processes, using safe techniques, making accurate observations, and improving reliability.

This is an attributed Oak National Academy lesson sequence, not a completed or academically approved DASKEREL course. Supporting transcripts may depend on video, images, practical equipment or teacher explanation. Follow each lesson’s supervision guidance. For religious education and RSHE, follow the school’s syllabus, policy and safeguarding procedures.

Prior knowledge

  • Light moves in straight lines to form a shadow in the same shape as an opaque object.
  • A light ray is just a line that shows the direction light travels in.
  • A light source is seen when light from it travels into the eye.
  • Objects are seen when light reflects off them into the eye.
  • Light enters the eye through a hole called a pupil.
  • Light is detected by special cells in the retina, on the back of the eye.
  • Light reflects off rough surfaces in many different directions.
  • An eye detects light reflecting off an object in the direction of the eye and enters it through the pupil.

Source curriculum references

  • Use appropriate techniques, apparatus, and materials during fieldwork and laboratory work, paying attention to health and safety
  • Make and record observations and measurements using a range of methods for different investigations; and evaluate the reliability of methods and suggest possible improvements
  • Other processes that involve energy transfer: changing motion, dropping an object, completing an electrical circuit, stretching a spring, metabolism of food, burning fuels
  • The transmission of light through materials: absorption, diffuse scattering and specular reflection at a surface
  • Use of ray model to explain imaging in mirrors, the pinhole camera, the refraction of light and action of convex lens in focusing (qualitative); the human eye
  • Light transferring energy from source to absorber, leading to chemical and electrical effects; photosensitive material in the retina and in cameras
