Challenges & Solutions
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.
25,000 students
4,000 young adults in science centers
Ages:11-18
400 schools20 countries
Ages:19-25
- Nano for Youth2009-2011
ORT Israel - 4 European projects
1 Israeli project
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
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?
Multidisciplinary Properties of materials
Chemical bonds Cell organelles
What can be taught?
Nanoscience & Nanotechnology basic literacy
• Nanoparticles• Nanodevices• Nanocomposites• Nanocrystalline Materials• Nanofibres• Thin-films & Coatings• Fullerenes & Carbon
nanotubes• Colloids
• Self-Cleaning coatings• Integrated Circuits• Solar cells• Quantum Dots• Nanomedicine• Nanoscale Drug Delivery
• Nanometre• Nanoscale
• Surface/Volume• Biomimetics• Self assembly• Enhanced Properties:
Mechanical Chemical ReactivityElectrical and ThermalOptical
• Nanoparticle's Toxicity
How can NT be taught?
Four basic models:
Extracurricular – Happenings, excellence classes
Enrichment of curriculum
Modules within another subject
Stand-alone subject
- Nano for Youth
Solutions
Set of small components
Happenings; one day modules
Challenges tackled
middle-school level
frontier subjects
Coping with an abstract field
Not sacrificing basic science
- Strongest Features
Experiments
Role-Plays & Virtual dilemmas
Video
Scientific background
- Greatest problem
Mainly for strong knowledgeable teachers
