Eyes

Summary: 
Look at your own eyes, dissect a cow's eye and learn about how our eyes work.
Science content (2016 curriculum):

Physics: Light and Sound (1)
Resource: 
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).

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_blindnes...
