Refraction - according to hyper-physics Refraction occurs when a light ray passes from a fast medium to a slow medium.
Total internal reflection - according to wikipedia Total internal reflection "occurs when a propagating wave strikes a medium boundary at an angle larger than a particular critical angle with respect to the normal to the surface."
Fiber Optics - according to hyper-physics when light rays travel on optic fibers

MS-PS4-2.
Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.[Clarification Statement: Emphasis is on both light and mechanical waves. Examples of models could include drawings, simulations, and written descriptions.] [Assessment Boundary: Assessment is limited to qualitative applications pertaining to light and mechanical waves.]
Questioning Script
Questioning Script
Prior knowledge & experience:
Water refracts light
Root question:
When you shine a laser through a stream of water exiting a 2 Liter bottle, what will happen?
Target response:
The light will use the water as an optical channel.
Common Misconceptions:
The most common misconception would be that the light would go straight, rather than following the water.

Photographs and Movies
Put all photos in the class Picasa Album and photo of light pipe in dark room, and photo of light pipe in light room. Do not upload the photos directly to this wiki as there is not enough memory in the website.
Put all movies in your own Youtube account. Make sure that the account is set for public viewing. Insert the Youtube videos here.
