Lesson Plan: Refraction of Light at a Boundary between Two Media Science
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe the deflection of light rays at the boundaries of different media.
Students will be able to
- recognize simple analogies of refraction,
- recall what is meant by a boundary between two media,
- recall that light rays travel in straight lines,
- recall what is meant by the normal to a surface,
- recall what is meant by the term angle of incidence for refraction and be able to identify it on a diagram,
- recall what is meant by the term angle of refraction for refraction and be able to identify it on a diagram,
- recall that when a light ray is incident on the boundary between two media along the normal to the surface, it is not deflected,
- measure angles using a protractor.
Students should already be familiar with
- what angles are.
Students will not cover
- refractive index,
- speeds of light in media.
