|Enter the fascinating world of Materials and uncover the surprising science behind everyday stuff!
February 9 - May 12
Discover the secrets of everyday stuff! Enter the fascinating world of material and uncover the surprising science behind the stuff we use every day. This hands-on exhibit examines the always amazing and sometime bizarre world of modern materials and provide a glimpse of where the future of materials research might take us.
AMAZING MAGNETIC LIQUIDS
Magnetic liquids are liquids that can respond to magnets - this is done by suspending microscale or nanoscale magnetic particles in fluid. In this area, you can play with both. Using magnets, manipulate a pool of ferrofluid and make it "dance". This materials is put to use i many diverse areas, from the operating room to your home entertainment center.
Younger children can discover materials through hands-on experimentation. Put different materials under the lens of a microsope camera to see how they look magnified, larger than life. Play tunes ona wooden xylophone and a xylophone of mixed materials -- do similar materials sound the same?
Get a look at materials from the macro (or naked-eye) scale down to the nano scale. Intricate structures are revealed. Find out how scientists "feel" atoms using atomic force microscopes. Be the "materials scientist" and get down to details.
STRUCTURES AND DEFECTS
Are defects always bad? It depends on the properties the scientist is trying to create. Play with a sheet of ball bearings and discover how this simple model can be used to investigate the role 'grain boundaries' play in creating stronger metals.
Drop the ball bearings to see which metal plate gives the ball the most bounce. The ball that keeps going and going and going is bouncing on a plate made of Liquidmetal(R) alloy, a type of amorphous metal and one of the world's hardest materials. Discover what makes it so hard and how this metal can improve your golf game and help a patient in the operating room.
MATERIAL SCIENCE-OVERVIEW VIDEO
How does materials science use atoms and molecules to design the "stuff" of our everyday lives? How has it changed human history and how does the performance of materials grow from their structure, properties and processing? In a special video, you will meet materials scientists who bring all of this together.
Below are two helpful guides for educators and families in preparation for experiencing the exhibit at ECHO:
