Researching the eye

Monday, April 12th, 2010

Now that we know what about the structure and function of the eye, let’s try and answer these questions:-

  • How do optical illusions (such as Optical Illusions) work?
  • Explain the evolution of the eye.
  • Compare the eyes of predators with those of their prey.
  • What is stereoscopic vision and how does it help animals survive?

Get into groups of 3 or 4.  Each person in your group should choose one question to research and answer.  Spend about 30 mins on this.  Come back together as a group and share your answers with each other.  Once each member of the group has responded, write down at least 2 follow-up questions for each topic, then try and answer those.

Check out lottolab.  Watch the TED video and then play around the site.  There are loads of optical illusions to keep you entertained.

And now get back to your mock revision….Friday 19th March is looming!
