The lens atthe other end of the Telescope iscalled the objective lens. Light froma distant object is focused by theobjective lens to form an image infront of the eyepiece. The eyepieceacts as a magnifier and enlarges thatimage. The magnification of thetelescope can be found by dividingthe focal length of the objective bythe focal length of the eyepiece. 2 converging lenses (convex lenses) telescoping tubes (mailing tubes) manila file folder scissors knife or saw glue 1 white poster board red and black tapeThe student will construct a simplerefracting Telescope and calculate Standards Science as Inquiry Physical ScienceMathematics Standards Problem Solving Communication Connection Computation/Estimation MeasurementLenses, Refraction54 Light, Color, and Their UsesOptics: An Educator s Guide With Activities in Science and Mathematics EG-2000-10-64-M
