The Physics Classroom: Refraction and Ray Model of Light: Refraction by Lenses
Students use this tutorial to investigate the refractive ability of converging and diverging lenses.
Physics Aviary
Physics Aviary: Lens Lab
This lab is designed to have students investigate the changes that occur to images formed by converging lenses based on the focal length of the lens, the height of the object and the location of the object. This video will help...
Ducksters
Ducksters: Physics for Kids: Lenses and Light
Kids learn about lenses and light in the science of physics including concave, convex, converging, diverging, focal point, meniscus, and Plano lenses.
PBS
Pbs Learning Media: Lens and Mirror Lab
Determine the location of the image in this interactive simulation of a lens and mirror optics bench. Both converging and diverging lenses and mirrors are included.

Illustrated diagrams in this tutorial help students understand the properties and functions of lenses.
Khan Academy
Khan Academy: Thin Lens Sign Conventions
Have you ever wondered why some people need glasses and others don't? It's because of the way light is focused by the lens in your eye. This lens, like magnifying glasses, eyeglasses, and contact lenses, is considered a thin lens.
Georgia State University
Georgia State University: Hyper Physics: Thin Lens Equation
This is an informative site from Georgia State University. It gives a discussion of the thin lens equation and an illustration of its use in determining the image distance based upon the object distance and the focal length.
