Bionic eye module 2


Learning Outcome: Students construct a representation of the human eye to illustrate how an image is produced on the retina.

Design descriptors

  • Students complete a quiz to identify any misconceptions related to light and seeing.
  • Students complete a range of investigations to challenge common misconceptions.
  • Students use a model to explore how an image is constructed on the retina using a lens system.
  • Students dissect a cows eye (virtually or in the lab) to learn the components of the eye.
  • Students construct a representation of the eye to demonstrate how optics focus an image on the retina.

Assumptions/Prior knowledge

  • None specified through it is anticipated that students will be starting the outcome with a series of misconceptions.

Misconceptions (common, not exhaustive)

  • Light just exists and has no origin.
  • You can see in the dark.
  • Light does not need to enter the eye for vision of objects to occur (i.e. light only needs to illuminate an object).
  • Sight is an active process where something leaves the eyes (i.e. feeling a stare).
  • Objects emit light (as opposed to reflecting light).
  • Objects do not reflect light (light remains with the object).
  • Light only travels short distances or not at all.
  • Light can only be reflected off shiny surfaces.
