Product Description
Video and lesson investigations on the topic of owl eyes. Key concepts include:
- Animals need to keep an eye on what is going on around them.
- They have developed ways of doing this that are appropriate to their life-style and environment.
- Eyes are adapted for particular purposes.
- These adaptations have evolved to suit the particular needs of the animal in relation to its survival in the environment in which it lives.
- Most owls are nocturnal and hunt at night.
- The light-sensitive layer of the retina contains two types of photo receptors know (because of their shape) as ‘rods’ and ‘cones’.
- Rods register images in black and white, while cones
are responsible for color vision. - Owl eyes are rich in the light-sensitive rods for black and white night vision. However, they have a few cones so they are almost color blind.
