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...

"Exploring the Universe: Imagining Life" is a hands-on activity in which visitors imagine and draw an extreme environment beyond Earth, then invent a living thing that could thrive in it. They learn that NASA scientists study extremophiles on Earth to...

Nanoscale science and technology ("nano" for short) is all around us and growing rapidly. Learn how you can use nanotechnology to clean drinking water right now!

"Biotoxicity" is an experiment that explores the antimicrobial properties and biotoxicity of nanoscale particles of silver. Students first produce nanosilver and then use the rate of respiration of yeast in the presence of different forms of silver to compare their...

The purpose of this activity is to use electrochemistry techniques to generate colloidal silver and then utilize the colloidal silver to determine if the growth of the bacteria Saccharomyces cerevisiae or Escherichia coli can be inhibited.

The cholera bacteria in this scanning electron microscope image cause a potentially fatal disease of the digestive system. • SIZE: These bacteria are each about 500 nm wide and 1-2 µm long. • IMAGING TOOL: Scanning electron microscope

This lab is designed to have students develop and implement their own experiment to test the antimicrobial properties of silver nanoparticles. Students will be required to document and communicate the entire process via their scientific notebook. Students will also consider...

To avoid using antibiotics and harming your helpful bacterial residents, see how an engineered virus plays the part of nanomedicine sheriff to fight specific bacterial bandits during an infection. Participants assume the identities of good and bad bacteria of the...

This lab will allow students to use the pure silver nanoparticles they synthesize to create antibacterial socks. They will compare their socks with socks that have been treated with a commercial silver spray, socks that have been treated in a...

Howtosmile is a collection of the best educational materials on the web, in addition to learning tools and services – all designed especially for those who teach school-aged kids in non-classroom settings. earch over 3,500 of the very best science...

What You Can’t See Is All Around You. Mysteries of the Unseen World will transport audiences to places on the planet they've never been before, to see things that are beyond their normal vision yet are literally right in front...

Students will learn about the differences in physical propoerties at the nanoscale as compared to the same materials at the macroscale. The students will demonstrate the appropriate use of a spectrophotometer and will convert between different units of measurement. This...

This activity—in which students test a local water supply—is designed to be used as an extension to classroom activities related to treating foul water for consumption. This activity should be done after students have been introduced to the concept of...

Science rapper Mike Wilson AKA Coma Niddy has created several different nanotechnology videos. Did you know that silver has antimicrobial abilities? The same silver that is in jewelry can kill germs, fungus and bacteria. Some scientists have developed nano-silver which...

Students will calculate surface area, draw graphs, and approximate the populations of bacteria and nanobes. Before starting this lab, the student should understand how to 1) calculate the surface area of a circle, 2) draw and label a graph, 3)...
