Lesson Plan: Concave Lenses Science • Third Year of Preparatory School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to identify the optical properties of concave lenses.
Objectives
Students will be able to
- describe what a lens is,
- describe what a concave lens is,
- identify the optical axis of a concave lens,
- identify the center of curvature of a lens,
- describe what is meant by the term diverging,
- identify the radius of curvature of the lens,
- recall that the focal length of a lens is the distance between the center of the lens and its focal point.
Prerequisites
Students should already be familiar with
- the idea that light travels in straight lines,
- the refraction of light at the boundary between two media.
Exclusions
Students will not cover
- monoconcave lenses.
