Materials Matter: It's a Nanoworld After All

children gathered around a table with a woman showing them an experiment Mindy Bowen performs the Materials Matter show at The Discovery Center in Springfield, MO.

Working together, the MRSEC and the Franklin Institute have produced the Materials Matter museum show, a 60 minute cart-based interactive exploration into the "micro" mechanisms behind the unusual and surprising "macro" behavior of materials such as aerogels, shape-memory alloys, polymers, electronic ink, and zeolites. We've distributed 22 copies of this show to science museums nationwide.

View the shows below to learn more about each demo. Each link has information on procedures and F.A.Q.'s.

Demonstrations

Jon Nese of The Franklin Institute demonstrates the amazing insulating properties of Aerogel

Aerogel

Aerogel is the lightest and lowest-density solid known to exist. It is typically 50-99.5% air, yet can hold 500 to 4,000 times its weight in applied force!

Graduate Student Dave Fleming demonstrates how electronic ink works using the egg tray and ping pong balls.

Electronic Ink

Electronic paper is made up of tiny balls that are white on one side and black on the other. The balls are sandwiched in between 2 sheets of rubbery plastic material. The balls can switch colors when they come close to a positive or negative charge. It is similar to when your hair is attracted to a balloon because of static cling.

Gore-Tex®

The Gore-Tex® demonstration shows the properties of how a microporous material can allow only molecules of a certain size to pass through.

Gummiworms demonstration at the Museum of Science and Industry (Chicago, IL).

Gummi-worms

The word polymer can be broken into two parts, "poly" means many and "mer" means parts. A polymer is made of many parts called "monomers." Gummiworms are a particular type of polymer which has been "cross-linked." Cross-linked polymers chains are tangled together which makes them strong.

Rachel Barry demonstrates how the sandhand goes from flimsy to moldable.

Mystery Material

The sand hand demonstrates the basic properties of sand and other granular materials when placed in a vacuum.

Karianne Smith demonstrates Mystery Mix at the Franklin Institute in Philadelphia , PA.

Mystery Mix

The mysterious mixture appears to be made up of one gray substance. When we use a magnet we can separate the mixture into two materials. One is a black iron powder that is attracted to the magnet and the other is a white powdery substance, sand, which you may have seen at the beach!

Children watch Nitinol wire return to its original shape at the Discovery Center in Springfield, MO.

Nitinol

Nitinol is a shape memory alloy, a mixture of two types of metal (in this case nickel and titanium) that will bend but will return to its original shape when heated.

Students pull a model of cross-linked polymers out.

Six Pack Rings

The word polymer can be broken into two parts, "poly" means many and "mer" means parts. A polymer is a huge chain-like molecule made by combining many smaller parts. Six-Pack Rings are made from specific type of polymer referred to as a "plastic."

Yang Wang shows the Zeolite demonstration.

Zeolites

A zeolite is a material (natural or synthetic) with a crystalline structure made up of silicon, aluminum, and oxygen in a regular pattern. These molecules act as a "cage" to trap certain molecules selectively.
