Product Details

Wire with a memory! Nitinol wire was discovered in 1961 and has “shape” memory. When placed in cold water it can be bent into any shape. Put into hot water, it springs back to its original shape. Shape memory alloys are discussed in the provided instructions. Price is per inch; may be purchased in any length requested.

Performance Expectations

MS-PS1-3: Gather and make sense of information to describe that synthetic materials come from natural resources and impact society.
MS-PS1-4: Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.
HS-PS2-6: Communicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials.
