Driving Question: How can we hide a “secret” object in plain sight?  How large of an object can be cloaked?

Synopsis: Students will construct the Rochester cloak, an optical cloaking device that operates in the visible spectrum, and determine where the cloaked regions are by calculating the size and location of images. Students will successfully hide an object in the Rochester cloak.

Physical Science NYSSLS Standards: Students will
  • Use mathematical models to determine relationships among the size and location of images, size and location of objects, and focal lengths of lenses and mirrors.
