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

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
