Session 15 - Visual Perception
ERA's are due today!!!
Open up with blind fold activity...
Outline the activity as the following:
- Students pair up for the activity
- All students are told that they will be going on a tour of the school - blindfolded!!! OMG
- Before both pairs head out each person must make up the route their partner will be taking around the school - here are the areas that could be visited:
- Gym
- Science
- Wood Tech
- Library
- Art Rooms
- Each student must visit each of the 5 locations - the order is up to their partner...
- The non-blindfolded person must then navigate their partner around their made up route.
- Once the blindfolded person is in the right location - they then must guess where they are using their senses....
- Once all 5 locations have been visited - partners swap roles and the same procedure is undertaken.
Once all participants are completed they must meet at the bottom of the stairs near the staffroom, where the teacher will be waiting to take the students back up to class.
Reflection Questions - to be completed in workbook:
1) While blindfolded, how did you make a judgment on your location?
2) Did you find it easy knowing which location you were in?
3) What was the most difficult aspect of the activity?
Students are to place the following in their workbooks:
The Visual Perception System
Sensation is the process of
our sense organs and receptors detecting and responding to sensory information
that stimulates them. Sensory information can be from internal as well as
external sources.
Perception is the process by
which we give meaning to sensory information, resulting in our personal
interpretation of that information.
Discuss the above relating it to the previous activity - What if we had no sense of smell, no hearing? Would that make it more difficult???
Students are to read through 69 - 71 and complete Check Your Understanding 3.1 in their workbooks.
Discuss the idea of Synaesthesia - read 'Focus on Research' and watch youtube clip:

H/W - Read through 72 to 75 and complete Check Your Understanding 3.2 in their workbooks

Due next session, Friday 9th March
Session 16 - Light, The Eye, Colour & The Visual Reception Process
Open up with the discussion about the eye's response to light - the concept of light allows all of us to see - read through the passage concerning the Visible Light Spectrum. Discuss main ideas...
Move onto processes concerning how light enters the eye and the result of such a phenomenon. Read through 'The Eye's Response to Light' passage, watch clip:
http://www.youtube.com/watch?v=15P8q35vNHw then handout eye diagram.
All students are to draw their own flowchart in their book that represents the process of light entering the eye - only 5 minutes to do this - sketch in workbook...
Pick student to run through their interpretation using the materials (torch & eye model) and their instructions - show to the whole class...
Move onto:
Photoreceptors: Rods & Cones
The retina consists of a number of layers of light sensitive neurons. In order for the lens to focus an image, light must pass through the retina's outer layers, which are made up of additional nerve cells. Rods and cones, the sensory receptor cells for vision, form the back layer of the retina.
- Read through Photoreceptors: Rods and Cones (pg 75, 76 & 77) and copy table 3.2 in workbooks.
- Check Your Understanding 3.3 in your workbooks.
- Read through the Visual Perception Processes (pg 81 & 82) and complete the Jigsaw Activity in workbooks...
H/W: Complete the Jigsaw Activity in workbooks and read through the 'Gestalt Principles - Grouping & Separating' section of the textbook (pg.84 -86) and fill out the appropriate table.
