Overview
Description:
"Snowflakes" is a public presentation that introduces nanoscale science through the subject of snowflakes. Visitors learn that the complex structure of snowflakes results from the nanoscale arrangement of water molecules in an ice crystal, and that snowflakes are examples of self-assembled systems studied by nanoscientists. During the program, visitors watch videos of snowflakes growing and observe real ice crystals growing in a chilled chamber.

Public SEM images of snow
Dartmouth has some awesome SEM images of snow crystals that might enhance this program.

They have a history of releasing SEM images into the public domain, so they'll probably let you use these, too.

I used a shortened version
I used a shortened version of this program with a group of Girl Scouts. They loved it! I used thread instead of fishing line and it worked just fine.
