Bring amazing real-world modern materials into your classroom! This multi-demonstration kit includes:
• Ferrofluid A magnetic fluid created by extremely small Fe3O4 particles. Dramatically demonstrate the unique physical properties of ferrofluid and how magnetic nanoparticles respond to a magnetic field. This application was invented by NASA to control liquids in space!
• Liquid Crystals Matter that behaves as both a liquid and a crystal. Liquid crystal molecules move independently like a liquid and also organize themselves like a crystalline solid. Temperature changes the molecular alignment of the crystals, creating different colors at various temperatures. Used in liquid crystal displays (LCD) for laptops, optical imaging, and whimsical items such as mood rings.
• Nitinol Wire This nickel-titanium metal alloy has a “memory!” Construct the desired shape of the nitinol wire in cold water. Then, place it in hot water and watch it quickly and forcefully spring back into its original shape.
Includes a reproducible student worksheet and detailed Teacher Notes with instructions, tips, and answers to all questions. Enough materials are included to perform the demonstration seven times.
Concepts: Nanotechnology, magnetic properties, colloids vs. solutions, liquid crystals, diffraction, metal alloys, crystal structures.
Time Required: 40 minutes
Chemicals Provided: Ferrofluid, cholesteryl oleyl carbonate, cholesteryl pelargonate, contact paper, aquarium thermometer, vials, nitinol wire.
Additional ResourcesNo Additional Resources at the time.
