Converging Lenses
Any incident ray traveling parallel to the principal axis of a converging lens will refract through the lens and travel through the focal point on the opposite side of the lens.
Any incident ray traveling through the focal point on the way to the lens will refract through the lens and travel parallel to the principal axis.
An incident ray that passes through the center of the lens will in effect continue in the same direction that it had when it entered the lens.
Standards
NGSS Science & Engineering Standards
Developing and Using Models
Modeling in 6–8 builds on K–5 and progresses to developing, using, and revising models to describe, test, and predict more abstract phenomena and design systems.
Develop and use a model to describe phenomena.
NGSS Cross-Cutting Concept Standards
Structure and Function
Structures can be designed to serve particular functions by taking into account properties of different materials, and how materials can be shaped and used.

PS4.B: Electromagnetic Radiation
When light shines on an object, it is reflected, absorbed, or transmitted through the object, depending on the object’s material and the frequency (color) of the light.
The path that light travels can be traced as straight lines, except at surfaces between different transparent materials (e.g., air and water, air and glass) where the light path bends.
Questioning Script
Prior knowledge & experience:
We see an object because it reflects light to our eye and is in our line of sight.
Root question:
How does light refract through a double convex lens?
Target response:
An image is inverted when the light reflected off of it passes through a convex lens.
Common Misconceptions:
State common misconceptions
Photographs and Movies
Applications to everyday live
Phet Simulation
Lenses are used in microscopes, telescopes, eyeglasses, cameras, and magnifying glasses.
