Students are invited to form groups (2-3 students in a group) to devise a cloaking device, based on the You tube video of Professor Howell and his graduate student Joseph Choi from University of Rochester in New York . Students are first brought to learn the rules for drawing light rays through a converging lens in a Gizmos animation. Inquiry-guided worksheets instruct students to view the You tube and engage in a conversation of where cloaking is of value and how does it work. They are to map the regions where cloaking works by plotting their data on graph paper.
