Nanofibers: Why Go Small?

High schoolers build metal atomic models using styrofoam. In this chemistry instructional activity, students identify the different unique properties of metals. They explain how metal atoms bond.

Young scholars explore the world of nanotechnology by synthesizing ferrofluids in a series of chemical reactions. In small groups, they follow the procedure to create the ferrofluids using precise measuring techniques. They test the...

Pupils relate the presence of nanofibers in clothing to its ability to repel stains. They observe and contrast the characteristics of nanofiber, Scotchguard treated, and regular fabric then test the stain resistance of each fabric...

I scream, you scream, we all scream for ice cream! Even high schoolers enjoy making ice cream. This laboratory exercise has them record the temperature changes throughout the process of liquid becoming solid, graph the results, and...

Nanoparticles have toxic effects on plant and animal life—even though you can't see them. The second lesson of a two-part series has young scientists conduct an experiment that exposes plant and animals to nanoparticle pollutants. They...

Students explore the surface ratio of an object.  In this surface area to volume activity students construct a data table, make calculations and create a graph. 

Nanotechnology is described for emerging engineers. Instructions for converting nanometers to meters is provided. Finally, the step-by-step laboratory procedure for measuring the size of an oil molecule is walked through. What a terrific...

Tiny discoveries won big at the 2016 Nobel prize ceremony, recognizing chemists who developed new machines out of molecules and pushed the limits of nanotechnology. Individuals see how physicists created new materials through topology...

Students explore current applications of nanotechnology in various industries, including medicine, space development, environmental protection, and defense.

Students study nanotechnology and investigate the dimensions of a nanoscale.  In this nanometer study lesson students will see how truly small a nanometer is by measuring things such as a piece of hair.
