Create and use a pinhole magnifier.

This site from Georgia State University Physics Department provides a discussion of how light refracts through the lenses of a microscope. Demonstrates the parts of a microscope and includes an interactive form in which the magnifying...

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.

A discussion of how to make a magnifying lens exhibit using a water-filled flask and a light bulb. Consists of assembly instructions and a "To do and notice" section. Great for a teacher demonstration or a student project.

To learn about the devastating effects of oil spills, students use magnifying lenses to examine feathers, and name and describe characteristics of the feathers.

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.

In this introduction to light energy, students learn about reflection and refraction as they learn that light travels in wave form. Through hands-on activities, they see how prisms, magnifying glasses and polarized lenses work. They also...
