Nano Library Kiosk

Imagine going up to a kiosk in your local library and actually touching the surfaces of nanoscale objects scaled up to human dimensions! Using innovative 3D-tactile models this kiosk for libraries allow visitors to feel the surfaces of nanoscale objects, thereby experiencing the amazing nanoscale structures that give these materials their unique properties. Developed by the Discovery Center Museum in Rockford, Illinois and the Institute for Chemical Education (ICE) at University of Madison Wisconsin.

The Water Race: Hydrophobic & Hydrophilic Surfaces (High School curriculum lesson)

This activity developed by NNIN explores how nanotechnology can be used to change the properties of a copper surface so that it either attracts or repels water. It is appropriate for middle school and high school students.

Nonpolar molecules that repel the water molecules are said to be hydrophobic; molecules forming ionic or a hydrogen bond with the water molecule are said to be hydrophilic. This property of water was important for the evolution of life. Hydrophobic interaction plays the most critical roles in the formation of the lipid bilayer of the cell membrane and the folding...

Mentos and Soda Explosion

Presenter puts Mentos candy into soda to create a soda fountain. This is a dramatic demonstration of the effects of surface area. This demonstration isn’t heavily focused on nanotechnology,but can be a spectacular finale that you add on to other nano demos like Intro to Nano or Surface Area. (It’s probably best as a substitution for Alka-Seltzer, rather than being performed with it.) It’s also just a crowd pleasing demo that briefly mentions nano.
