From the Teacher's Desk: Snowflakes
Do you know a snowflake's shape is created long before it arrives on the Earth's surface? First, an ice crystal surrounds a miniature piece of debris, inside a cloud - and forms a snow crystal. The shape of the snowflake will depend on the temperature of the cloud. When the crystals begin to fall from the clouds, they bond together to form snowflakes. Each snowflake is comprised of up to 200 separate snow crystals. These crystals form into one of seven different shapes. The Stellar crystal is the most popular shape. This famous star shape inspires artists and photographers.
Study Snowflakes
If you'd like to study snowflakes with your students, go outside when it’s not windy and the temperature is between -12 and -16 degrees. Bring a piece of dark cloth with you. This will make it easier to view the crystals. You might like to use a microscope or magnifying glass to enlarge the crystal for easy viewing.
"Snowflake" Bentley
In 1885, a man named Wilson "Snowflake" Bentley learned how to make the crystals show up in photographs. Wilson lived in a small town in rural Vermont and he adapted a microscope to a bellows camera and discovered that he could take a photo of a single snow crystal. He captured over 5000 snowflakes during his lifetime and he never found any two alike. You can find more information, photographs, and resources at the Snowflake Bentley official website.
