Students review some basic biology by talking about how the eye works. They cover the concepts behind laser surgery as a treatment for saving sight. They begin to recognize the overlap of disciplines (physics and biology) required for...

Students explore the use of lasers. In this "lasers" science and career education lesson, students search the Internet to find uses for lasers and make a list of companies that use or produce lasers. Students complete a lasers and making...

In this simulation activity, young biologists examine blood types to determine whether the death rate in a hospital was caused because of incorrect identification of patient blood types. You will need obtain and follow the procedures of...

Middle schoolers examine the properties of light and the behavior of light during interference.  In this electromagnetics lesson students explain behaviors of light.

Students study the structures of the human eye.  In this eye device lesson students examine different eye problems and devices that can help to resolve them. 

Students discuss different ways engineers use light. In this engineering lesson, students are introduced to the properties of light and the way light is used. They view a demonstration of light waves using a slinky, and practice using...

Students determine their own eyesight and calculate what a good average eyesight value for the class would be. They examine how technology enhances eyesight and how engineers play an important role in the development of these technologies.

Information is provided about laser surgery, which is used to correct vision problems and eliminate the need for glasses or contacts.

Theodore Maiman built the world's first operable laser. Ironically, Maiman's first paper announcing this momentous achievement, which many other scientists had been racing to complete themselves, was rejected. Since then, however, lasers...
