What is Nano?
Nanometer (nm) = 1 millionth of a millimeter, 1 billionth of a meter
Nanoscience: 5-500 nmParticles, fibres, layers
Atoms and molecules (chemistry) 0.1-2 nm
Microscopy: microns and milimeters
Nanoscience: the study of phenomena and manipulation of materials of sizes 5-500 nm, where properties differ significantly from those at a larger scale.

Challenges of teaching NT
University level middle-school level
Frontier subjects: uncertainty and flux
Coping with an abstract field
Teaching without sacrificing basic science
Teacher training
Price: labs & materials

Why teach NT in school?
Lesson from GMO – Informed critical thinking citizens
Informed citizens critical thinking citizens rational decisions
Captive audienceBasic concepts
![Page 8: From NanoYou to secondary school Nano studies, Nira Shimoni-Ayal](https://reader030.fdocuments.in/reader030/viewer/2022032617/55a977c21a28ab710e8b4608/html5/thumbnails/8.jpg)
Lesson from GMO – Informed critical thinking citizens
Raises motivation for science studies
Why teach NT in school?
Socially relevant –dialogue about ethical,
legal, social (ELSA) aspects
Attractive – new, exciting & relevant; real-life applications already
on shelves

Lesson from GMO – Informed critical thinking citizens
Motivation for science studies
It’s there - Fits naturally in middle school scientific curriculum
Why teach NT in school?

How can NT be taught?
Four basic models:
Extracurricular – Happenings, excellence classes
Enrichment of curriculum
Modules within another subject
Stand-alone subject
![Page 12: From NanoYou to secondary school Nano studies, Nira Shimoni-Ayal](https://reader030.fdocuments.in/reader030/viewer/2022032617/55a977c21a28ab710e8b4608/html5/thumbnails/12.jpg)
