The Experts

Talk Outline WHY YOU SHOULD CARE Lesson 1- What Color Is Gold! Lesson 2- Too Small To See? WHY YOUR STUDENTS WILL CARE

Objectives Students will understand –“nano” –Scale (km to nm) –Nanoparticles behave differently than bulk –Nanoparticles influence substrate –Green Chemistry

National Standards 9-12 A: Science as Inquiry B: Physical Science E: Science and Technology F: Science in Personal & Social Perspectives G: History and Nature of Science

Background Experimental procedures Familiarity with atoms Properties of matter Knowledge of metric system Human impact world

Lesson 1 What Color Is Gold? GET RICH QUICK

Sell Your Gold For Cash

“Green Chemistry” Au Synthesis

What Color Is GOLD???

Visualize Change At Nano Level Optical properties change due to size Au Not observed in bulk ~13nm to ~100nm

Lesson 2 Too Small To See? Discussion of Scale (Video) Measurement Activity

Demonstrate Size & Limitations

Misconceptions Material properties do not change with size. People are not effected by Nanoparticles..

Assessment Draw in scale Apply scale to substrate Demonstrate nanoparticle size influences substrate Visually demonstrate scale in a discipline (poster, powerpoint,video, 3D model) Design future examples of applications

Application To Life Consumer Products, Beauty, Electronics, Health, Medical, Manufacturing

Career Connections Nanotechnology Biologist EngineerChemistPhysicist Environmentalist Molecular Biologist Materials Scientist

Society Impact Informative understanding- SPENDING 2 million nano workers needed by million additional related jobs

Lesson Summary Green Chemistry Scale Properties (Optical) Demonstrating scale using models Real world connections
