Students learn about a class of materials called shape memory alloys. They will explore how these materials work and what applications these materials are used in. They will discuss phase transformations.
Design Challenge: Incorporating Shape Memory Alloys into Rube Goldberg Devices (Middle and High School curriculum lesson)
To encourage students to compare and contrast science and technology; experimental design and industrial design; and physics and its impact on nanotechnology. The students will be able to analyze and reflect on the forces, motion and energy transformations that can be shown by a Rube Goldberg Device and to experience the impact that Nitinol wire has on the device.
"Exploring Materials - Memory Metal" is a hands on activity in which visitors compare the properties of a memory metal spring to an ordinary spring. They learn that the way a material behaves on the macroscale is affected by its structure on the nanoscale.
This animated lesson explores ways a special kind of metal called shape memory alloys is advancing technology--everything from robots and the Mars Rover to braces!
