3.1.10 .B Describe concepts of models as a way to
predict and understand science and
technology.
3.1.10.D Apply scale as a way of relating concepts and
ideas to one another by some measure.
Apply dimensional analysis and scale
as a ratio.
Convert one scale to another.
3.8.10.C Evaluate possibilities consequences and
impacts of scientific and technological solutions.
Explain how small a nanometer actually
is.
Identify how on a nanoscale size certain
properties are affected

The study of objects and phenomena at a very
small scale, roughly 1 to 100 nanometers (nm)
A grain of sand is 1 million nm, or 1 millimeter, wide
An emerging, interdisciplinary science involving
Physics
Chemistry
Biology
Engineering
Materials Science
Computer Science

atoms
Current CD and DVD media have storage scale
in micrometers
New nanomedia (made when gold selfassembles into strips on silicon) has a storage
scale in nanometers
That is 1,000 times more storage along each
dimension (length, width)…
…or 1,000,000
times greater
storage density
in total!
