Students learn that light travels in a straight line from a light source and that ray diagrams help us understand how images will be created by a lens. This prepares students for the associated activity, in which they explore the concepts behind the workings of a pinhole camera.

Optical engineers design equipment to focus and control light for a variety of purposes — for uses in medical equipment, armed forces and recreation, among many others. Optical engineers design telescopes, binoculars and even the focusing lens on CD drives.Explain that light travels in a straight line.Draw a simple ray diagram.20TeachEngineering.orgLuke SimmonsFrank BurkholderAbigail WatrousJanet Yowellhttp://historyforkids.utah.gov/fun_and_games/photos/history.htmlS11416DAInternational_Technology_Education_Association-ITEA_STL_StandardsTechnologyC.
