Data and Light

Driving Question: How can we store more information on an optical disc?
 
Synopsis: Students will investigate the separation or track pitch for a CD and DVD and determine what the smallest possible separation or track pitch is for a Blu-Ray™ disc. Students will then develop a theoretical optical disc with a higher storage capacity.

Physical Science NYSSLS Standards: Students will

  • Evaluate questions about the advantages of using a digital transmission and storage of information.
  • Communicate technical information about how some technological devices use the principles of wave behavior and wave interactions with matter to transmit and capture information and energy.
CC Math Standards: Students will
  • Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems.  
  • Represent constraints by equations or inequalities, and by systems of equations and/or inequalities, and interpret solutions as viable or nonviable options in a modeling context.
