A tiny particle, such as a speck of dust, smoke, or salt, is at the center of every snowflake!
Snowflakes form when water vapor freezes in crystal form around a speck of dust or other debris in the air. These particles, called "cloud condensation nuclei" (CCN) may be only a millionth of a meter wide and weigh a trillionth of a gram!
If there aren't any CCNs around for the water vapor to crystallize onto, it will remain in the air as a cloud, even if it is cold enough to make snow. Water vapor clouds have been observed at temperatures as cold as -40 Fahrenheit (-40 Celsius)!
The shape of a snowflake depends on the temperature at which it forms!
Snowflakes are clusters of three-dimensional hexagonal (six sided) ice crystals. The crystals may form thin plates, needles, hollow columns, sector plates, or dendrites, depending on the temperature of formation. A typical snowflake is made of many such crystals stuck together, and can include crystals of more than one type.
Under certain conditions, small snowflakes group together to form giant ones. These giant snowflakes are 4 - 6 inches (10 - 15 cm) in diameter!

Qualities of snow
Songs, snacks, and games accompany
this resources for numerous snow art projects. Early elementary students
can create snowmen feet, tin foil snow, paper plate snowmen, and more.
The largest snowflake ever found was 8" by 12"! It was reported to have fallen in Bratsk, Siberia in 1971.
