Nano Object of the day


Integrated circuit chip look at with tools

Compact disk, Look at the spectrum of a point of light in a compact disk.

Use agar blocks to study syrface area to volume ratios. NNIN

Study nanoscale objects with light

Soap Film in a can, Create a soap film a few hundred nanometers thick using dishwashing soap and a film can.

Soap Film Interference Use waves drawn on paper to model interference of light in a thin film.

Soap Film Colors Observe which Colors will form when interference removes colors from white light.

Permanent oil slick Create interference colors with clear nailpolish floated on water lifted onto black paper.


Nano building tools

Model deposition and etching by using Lego's. NNIN

Use UV light to cure a polymer and make 3D builds NNIN

Anodize titanium using waterproof markers as resist

Heat quarters to build up oxide layers monitor the thickness with color change.

Etch a printed circuit board, or etch glass.
