Shape Memory Alloys

This experiment, presented by the National Nanotechnology Infrastructure Network, covers Shape Memory Alloys or Smart Materials. A Smart Material or Shape Memory Alloys belongs to a class of materials which displays the shape memory effect (SME); they possess the ability to radically change crystal structure or phase at a distinct temperature. The lab will "explore how smart materials work and what applications these materials are used in." Additionally, students will be provided with a brief history lesson about the origins of smart material. The experiment is quite fun, students will observe how smart materials can "think and do amazing things." A student and teacher guide is provided with the lab. Overall, this is a great exercise for any science classroom interested in the workings of nanotechnology.
