The Materials Science and Technology Teacher's Workshop (MAST) provides this activity as an introduction to the the photoconductive properties of semiconductors. The lab aims to "quantitatively determine how the electrical resistance of a cadmium sulfide photocell varies as a function of light...

This lesson, from the Technological Education Pathways Partnership (TEPP), compares some of the different light bulbs available to consumers. Light bulb types examined include incandescent, LED, and compact fluorescent lamp. Three PowerPoint presentations outline a test the output of incandescent...

Unit Description: FLATE, the Florida Advanced Technological Education Center for Manufacturing, has developed a series of “Made in Florida” lesson plans to prepare students for careers in manufacturing. These Lesson Plans are intended to enrich science, technology, engineering, and mathematics...

Many optical displays can be made using liquid crystal materials that have structure that is intermediate between that of liquids and crystalline solids. Liquid crystals are used in TVs, projectors, Flat screen monitors in computers and laptops. This article overviews different materials and how the...
