OPTICS & LIGHTRainbow GlassesBright lights explode into crystal clear spectra when you wear these Rainbow Glasses. Teach your students about color, light, refraction and line spectra with these simple, cardboard spectacles. Inexpensive, colorful and lots of fun. 531.5 lines/mm.AP1949 I $1.40Meter Stick Optics Bench KitExplore basic optics principles with a meter stick and simple attachments. Students discover how light travels and how lenses affect its travel as well as learn the basic properties of lenses in a series of hands-on lab experiments. Includes a single meter stick optics bench setup with meter stick, meter stick support, two exper-imental lenses, lens support, two candles, candle holder, optic target, screen support and complete instructions.AP6098 I $40.20Stroboscope, HandheldWith this durable handheld stroboscope, determine a spinning fan blade’s speed to less than 0.2% error, make a vibrating string appear at rest and show interference patterns in a ripple tank. Use coarse and fine adjustment knobs to “dial in” a flash rate from 100 to 10,000 flashes per minute. The four-digit LED display is easy to read during experiments. Xenon flashlamp can operate continuously for 5–30 minutes.AP6394 I $285.15Investigating Light and Optics—Student Laboratory KitActivity stations let students examine light, color and optics. Observe light reflection and refraction with mirrors, water and transparent objects. Investigate concave and convex lens properties, focus a “real image” and create a telescope. Compare plastics using polar-ized light, explore color mixing by addition and subtraction and study optical illusions to unveil color perception. Detailed instructions and Teacher Notes are provided.AP7055 I $155.45Build a Telescope—Classroom SetStudents build simple astronomical and terrestrial telescopes with 5X magnification, then experiment with the different designs and determine how the lens combinations work to magnify an object’s image. Classroom Set includes materials to build a total of eight telescopes—four astronomical and four terrestrial. Teacher Notes, reproducible student handouts and all necessary special-ized equipment are provided.AP6297 I $118.35Flinn C-Spectra®, 8” x 10” SheetFlinn C-Spectra® is an alternative to spectro-scopes for observing orders of the emission spectra of gases in spectrum tubes and spectra in flame tests. Because of its holo-graphic nature, every segment of C-Spectra produces the same pattern, so a single piece can be cut into smaller pieces for student use. C-Spectra is washable and should be cleaned with a soft cloth and mild detergent to prevent scratching. 200 lines/mm.AP1714 I $21.701,000+ PHYSICS & PHYSICAL SCIENCE PRODUCTS @flinnsci.com
