Nano-Silver
Nano-silver is used to kill bacteria in many different consumer applications. Nano-silver works better than regular silver particles because of its smaller size and subsequently greater surface area to volume ratio (more outside "sticky surface" to space inside).
The following activities will help you explore the basic ideas behind nano-silver technology and nanotechnology in general. Some are specifically about nano-silver, while the rest look at the ideas of surface area and volume. We hope you enjoy these activities!
Activities
Alka-Seltzer Rockets
A perennial favorite, this variation uses whole alka-seltzer tablets against crushed up ones to see who will win the blast-off count-down! Build your own simple rocket and race to see what kind of rocket fuel (crushed or whole) will launch first!
