surface area

This is a large group version of the Surface Area program. In this interactive stage presentation, audience members are measured in nanometers and demonstrate the effectiveness of "nano" silver in killing germs. Other highlights include a fireball that starts and...

"Nanosilver: Breakthrough or Biohazard?" is a public presentation which introduces audiences to the increasingly frequent use of silver nanoparticles in consumer products. During the presentation, visitors are guided through questions such as: What is nanosilver? Why is it used in...

"Exploring Properties - Surface Area" is a hands-on activity demonstrating how a material can act differently when it's nanometer-sized. Visitors compare the reaction rate of an effervescent antacid tablet that is broken in half with one that is broken into...

This is a cart demo about how nanoparticles behave differently, in part because they have a high surface area:volume ratio. Visitors learn that smaller particles have a much higher proportion of their atoms on the surface. Visitors unfold paper cubes,...

This lab is designed to help students understand how nanoparticles may be more effective catalysts by investigating how the surface area-to-volume ratio of a substance is affected as its shape changes. This lab is meant to complement a chemistry unit...

"Nanotech and Consumer Products" is a public presentation that introduces audiences to the growing role of nanotechnology in making consumer products, and encourages them to consider the potential environmental and health risks. During the presentation, visitors are guided through questions...

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...
