Why Nanotech?

• An opportunity to introduce science without
  textbook answers
• Nano cuts across many science/engineering
  disciplines allows students to approach science
  from many different vantage points
• Nano gets at many basic misconceptions, exposes
  student needs in powers of ten and relative scale
• Nano has inherent interest (Cutting Edge Cool)

Bottoms Up
Feynman's "There's Plenty of Room at the Bottom"
postulated the idea you could write the entire
Encyclopedia Britannica on the head of a pin.
This would require text to be text be 1/25000th
of its current size.

Whats Happening

• Carbon Nanotubes are sheets of Graphene (Carbon
  atoms in a single layer) rolled up into a
  super-strong thread tube. Is this Spidermans
  web?

But, what will we tell the kids?

• There are Nine Big Ideas in Nano (choose one or
  two)
• Size and Scale
• Structure of Matter
• Forces and Interactions
• Quantum Effects
• Size-Dependent Properties
• Self-Assembly
• Tools and Instrumentation
• Models and Simulations
• Science, Technology, and Society

Can my students learn this?

• Calif. HS student devises possible cancer cure
  By Steve Hartman
• If you ever worry about the future of America,
  there is no need it is in good hands. A high
  school student named Angela is proof of that. We
  think you'll agree she is nothing short of
  amazing. CBS News correspondent Steve Hartman met
  her on the road.
• Born to Chinese immigrants, 17-year-old Angela
  Zhang of Cupertino, California is a typical
  American teenager. She's really into shoes and is
  just learning how to drive.But there is one thing
  that separates her from every other student at
  Monta Vista High School, something she first
  shared with her chemistry teacher, Kavita Gupta.
• It's a research paper Angela wrote in her spare
  time -- and it is advanced, to say the least.
  Gupta says all she knows is its recipe -- for
  curing cancer.
• "Cure for cancer -- a high school student," said
  Gupta. "It's just so mind-boggling. I just cannot
  even begin to comprehend how she even thought
  about it or did this."
• "I just thought, 'Why not?' 'What is there to
  lose?'" said Angela.
