  1. 0 Convex and Concave Lenses Solving the Lens Mystery Lynn Garner & Sharon Holloway

  2. Lenses and Light • Lenses are curved pieces of glass that can be convex or concave. • Concave lenses cause light rays to spread out (diverge). • Convex lenses cause light to come together (converge) to a focal point.

  3. Refracted Light –Convex & Concave

  4. Concave Mirrors • Make-up mirrors are concave and magnify • Concave mirrors are used in reflectors, spotlights, and headlights focus light into beams

  5. Convex Mirrors • Convex mirrors curve outwards and are wide angle mirrors. • Convex mirrors are like rear view mirrors • They provide drivers and clerks with a wide field of vision.

  6. Review • Excel Survey Graph – Far/Near Sighted • Test Questions • Overall Graph

  7. Resources • Kasparie, Diane & Mary Young. Practical Applications of Optical Lenses: Telescopes & Projectors. 2002. • Discovery Education. Reflected Light and Mirrors. • Sharon Holloway – Fifth Grade Teacher • Lynn Garner - TST
