Summary Look at your own eyes, dissect a cow's eye and learn about how our eyes work. Science content Biology: Sensing, Organ Systems (4, 5, 6) Physics: Light and Sound (1) Activities in this lesson Eye study Eye dissection Lenses: magnify and invert an image Lenses bend light Eyes: blind spot Colour reversal illusions Eyes in predators and prey Colours change through filters Resource Evolution Procedure Do a selection of the activities. Other things to add: Show pictures of other animals' eyes - all different colours and pupils of different shapes e.g. eyes from Evolution book (see resource). Show a picture of a girl with cat eyes, and ask students to About colourblindness: About 1 in 12 men (8%) and 1 in 200 women in the world are colourblind, though not all the cases are extreme, and someone might not even realise they have partial colourblindness. Colour blindness is usually from a genetic cause (in your DNA and inherited from parents). The most common kind is red/green colourblindness, and is partial or complete loss of sensitivity to red and green colours. In the more extreme cases (protanopia - loss of red, and deuteranopia - loss of green) colours containing red or green appear yellow or brown, and blues and purples are confused. Less extreme cases (deuteranomaly - partial loss of green) are most common, where reds appear browner and purples appear bluer. https://en.wikipedia.org/wiki/Color_blindness#/media/File:Color_blindne… Find out what it is like to be colour blind: http://www.colourblindawareness.org Attached documents eyes_take_home_for_web.pdf Grades taught Gr K Gr 1 Gr 2 Gr 3 Gr 4 Gr 5
