      State standards and benchmarks addressed by this unit:

      P.1.24 Use the concepts of reflection, refraction, polarization, transmission, and absorption to predict the motion of waves moving through space and matter.
      P.1.25 Use the concepts of wave motion to predict conceptually and quantitatively the various properties of a simple optical system.
      P.1.26 Identify electromagnetic radiation as a wave phenomenon after observing refraction, reflection, and polarization of such radiation.

B Level Activities (15 points maximum)

1.  Create a Bulletin Board, poster or display to teach others about reflection.
2.  Create a bulletin board, poster or display to teach others about refraction.
3.  Create and perform a skit or trick using a mirror illusion for the class.
4.  Prepare a demonstration for the class showing and explaining total internal reflection in a prism. 
5.  Design an optical system using two or more mirrors including one plane and one curved mirror.  Be able to explain your system (including focal lengths, object locations, and image properties.)

“A” Layer Activities – Use “A” layer form (20 points maximum)

1.  Make a floor plan of an existing store, or devise a floor plan for an imaginary one.  Determine how much of the store could be monitored by a clerk if flat mirrors were placed int eh corners.  If you could use curved mirrors in such a system, would you use concave or convex mirrors?  Where would you place them?  Identify which parts of the store could be observed with the curved mirrors in place.  Would you recommend a store use your plan? Why or why not?
2.  Should Lasic be used to correct lens problems in the eye?
3.  Another question approved by Mr. Sailer.
