Lesson Plan

In Growing Your Own Snow Crystals, Caltech's Kenneth G. Libbrecht explains how teachers and even students can grow snow crystals in the classroom with a few materials and a two-liter bottle. All instructions for an excellent science experiment are included. (This activity can be used as a demonstration in lower grades.)



Students should be closely monitored during this experiment and may be asked to submit written notes from their work for evaluation.
