The first mention of the hexagonal form in relation to a snow crystal was made in China by Han Ying in 135 BC, in the publication "Hanshi waizhuan".
What are common snowflake shapes and sizes?
Why should we care about Snow types?
Symmetry, angles, and hexagon shapes of snowflakes and how water forms into ice crystals.
Children can easily learn mathematical concepts while making paper snowflakes.
Snowflakes are not square, 4 or 8 sided.
Snowflakes are generally 6 sided (hexagonal) but can also be two, three and 12 sided.
Snowflakes are composed of thousands of tiny, identical, hexagonal shaped ice crystals.
Snowflake instructions diagram the steps to create accurate snowflake designs based upon common scientific snowflake classifications.
Each snowflake instruction page explains how to cut snowflakes using the science of nature as your guide. Many of the patterns in our pattern library were designed from Snowflake bentley, the Snowflake Man photographs of actual snowflakes .
Make a flake for fun winter related craft patterns and projects. Use squares of origami, tissue paper, or other light weight paper, creative techniques and craft supplies to make a variety of snowflake designs.
Snowflake crystals form when water vapor cools and freezes inside clouds.
You might be surprised to find that snowflakes are not all six-sided.
Falling snow is called "Precipitated Snow".
"Precipitate" means: to condense as a vapor and fall from the sky.
Every snow crystal starts as "precipitation".
The book: "Rain, Hail, Snow and Sleet" teaches about "precipitation".
Snowflakes can consist of only 2 snow crystals or hundreds of snow crystals.
Snow crystals are frozen water molecules which bond to each other.
Snowflakes are formed when Snow Crystals grow into tiny, sometimes microscopic, "symmetrical" shapes.
"Symmetrical" means: proportional, or having an equal number of parts.
A perfectly formed 6-sided snowflake is called "symmetrical".
Every snowflake changes as it ages.
Changing snow is called "Metamorphosed Snow".
"Metamorphose" means: to change or transform into a different physical form.
Water vapor that has changed into snow crystals is "Metamorphosed snow".
It's true, just like human fingerprints are each different, every snowflake is different, although each snowflake is made up of hundreds or even thousands of tiny, identically shaped hexagonal crystals gathered together.
There are an infinite variety of snowflakes. Wilson (Snowflake) Bentley, an American farmer who devoted most of his life to the examination and photography of snowflakes, never found two identical snowflakes.
Snow crystal forms generally fall into broad categories, or Snowflake and Ice Crystal Classifications which are used to create a common form of reference to describe snow crystals.
Global Snowflake Network Scientists are enlisting volunteers to document the shape of snowflakes around the world.
Antarctica is the coldest place on earth. The next coldest places are a few areas in Russia.
The snowflakes that fall on Antarctica hold valuable scientific information about the atmospheric conditions at the time of their formation.
This long-term climatic and environmental information is contained in the dust, chemicals and gas that was trapped in the ice during the snowflake's formation.
The Antarctic ice sheet is a collection of snowfalls that fell over hundreds of thousands of years.
Snow flurries/snow showers: Snow that falls for short duration and often changes in intensity. Flurries usually result in very little accumulation.
