Bionic eye module 3
Overview
Learning Outcome: Students implement the principles of energy conversion to demonstrate the sequence of events leading to the perception of the image on the retina by the brain.
Module summary
Students gain insight into how light energy is transformed into chemical energy by retinal cells (rods and cones) and how the brain uses the signals from these cells to form a perceived image.
Design descriptors
- Students complete an activity that explores the idea that resolution is an important aspect of visual acuity.
- Students explore how a moving field of view can assist in constructing a representation of a static image in the brain through an identification game (to demonstrate that the visual cortex takes many pieces of information and collates them into a meaningful image)
- Students watch a video to support their understanding of the biochemistry of signal transduction in the eye and the role of the visual cortex in organisation and interpretation of stimulus information.
Key concepts and key skills
Assumptions/Prior knowledge
- An image (light) is required to form on the retina which serves as a screen (of sorts).
