4. Why Nano Education?? 0.8-0.9 million – US 0.5-0.6 million – Japan
The NSF estimates that by the year 2015 there will be a need for 2 million workers worldwide in the fields of nanoscience and nanotechnology.
million – US
million – Japan
million – EU
An additional 5 million workers will be needed in support areas for these fields
By 2015, nanotechnology is expected to be a $2.5 trillion “industry”

6. Understanding Size and Scale
Nanoscale
1-100nm in one direction
Differentiate
Macro, micro, nano, atomic
SPIE Baltimore 4/26/2012

7. What is a nano? A nano is one billionth of a meter or 10 -9 meters
A normal person can walk 32km or ~ 20 miles in one day. If a person were shrunk so that they were 1nm tall, how long would it take for them to walk the length of a dollar bill?
24 years
SPIE Baltimore 4/26/2012

8. How “big” is nano? A fingernail grows 1nm every second
If you take a pen and put a dot on your hand it is about 1 million nm in diameter
A sheet of paper is about 100,000 nanometers thick.
A human hair is 60,000 – 80,000 nm wide
Each bullet will click in one at a time Ask question, give several students a chance to guess before providing the answer. You may want to hold up a dollar bill.

10. Big Idea: Size and Scale
Factors relating to size and geometry (e.g. size, scale, shape, proportionality, dimensionality) help describe matter and predicts its behavior
SPIE Baltimore 4/26/2012

11. Size and Scale and NSES Standard B Physical Science (5-8)
Properties and changes of properties in matter
A substance has characteristic properties, such as density, a boiling point, and solubility, all of which are independent of the amount of the sample. A mixture of substances often can be separated into the original substances using one or more of the characteristic properties. (Comment on this standard: Properties have been shown to change as they approach the nanoscale where melting points, optical properties etc. change.)
SPIE Baltimore 4/26/2012

12. Size and Scale and NSES Standard B Physical Science (9-12)
Structure and properties of matter
The physical properties of compounds reflect the nature of interactions among its molecules. These interactions are determined by the structure of the molecule, including the constituent atoms and the distances and angles between them.

13. Size and Scale Learning Goal 1
In order to know the size of an object, it is necessary to be able to compare it to a reference point

20. Size and Scale Learning Goal 2
Some worlds are too small to be seen with the naked eye
Micro-, nano-, and atomic/molecular worlds.
Micro: single cells
Nano: 1-100nm i.e. diameter of DNA (2nm)
Atomic: <1nm i.e. hydrogen atom
(0.1nm)

21. Big Idea – Tools and Instrumentation
Development of new tools and instruments helps drive scientific progress. Recent development of specialized tools has led to new levels of understanding of matter by helping scientists detect, manipulate, isolate, measure, fabricate, and investigate nanoscale matter with unprecedented precision and accuracy.
SPIE Baltimore 4/26/2012

22. Learning Goal 1
Specialized tools are required to detect, measure, and investigate the nanoscale world because structures on this scale are too small to be seen with optical microscopes.
