Curated OER
Physics Lab Demo : Optics Light Box
Use a light box to experiment with light rays. The teacher uses prisms, convex, and concave lenses to refract light rays. Get your physics class excited about reflection and refraction by showing this video before you have them...
Khan Academy
Refraction of Seismic Waves, Cosmology & Astronomy
Mr. Khan uses the metaphor of a car to help explain the change in the direction of waves as they hit a boundary between two mediums. He then goes on to explain the relationship between the earth's structure and density and the waves'...

Bill Nye The Science Guy on Light, Bending & Bouncing
Beam me up, Bill! Explore how beams of light behave when they strike flat and curved surfaces. Bill bends light using a nifty contraption that streams three beams through a straight and a curved piece of plastic. He also defines and...

Disappearing Money - Sick Science! #049
Bring a little magic into the classroom. Fill a cup with water, place a plate underneath it, and watch a coin disappear. This is a great way to kick off a discussion involving the behavior of light and the concepts of reflection and...
Curated OER
Refraction
Refraction is the bending of light, changing its path. This phenomenon is caused by a change in the speed of the light waves. This video provides visual demonstrations of refraction through various media. It concludes by mentioning how...

Physics 11.2.1a - Refraction
All of the classic means of revealing refraction are employed in this interactive whiteboard presentation: a straw in a cup of water and light rays traveling through a piece of glass. On the drawing of light passing through glass, Derek...

Physics 11.2.3a - Snell's Law
Snell measured the angles of refraction through water and developed a formula for calculating a refraction. In this educational video clip, the teacher explains how it came about. It is most applicable to your high school physics class.
