Second Grade planned and designed snowflakes out of marshmallows and toothpicks after reading the book “Snowflake Bentley” by Jacqueline Briggs Martin.  They learned that the first snowflake was photographed by Wilson Bradley.  Snowflakes are formed when a water droplet freeze onto a dust particle.  This creates an ice crystal.  As the ice crystal falls to the ground, water vapor freezes and creates new crystals.  The journey that a snowflake takes as it travels to the ground will affect it size and shape.  This is why snowflakes are unique.
