A snowflake is a single ice crystal large enough to fall through the Earth's atmosphere as snow. Snow appears white in color despite being made of clear ice. This is because the many small crystal facets of the snowflakes scatter the sunlight between them. Each snowflake begins by forming around a tiny particle called is nucleus, accumulating water droplets which freeze and slowly from a crystal. Complex shapes emerge as the flake moves through differing temperature and humidity zones in the atmosphere and possibly combines with other snowflakes. Because of this, snowflakes tend to look very different from one another. According to scientific consensus, all snowflakes are considered to be different from one another because as they fall through the atmosphere, they encounter slightly varying temperature and humidity levels, leading to unique growth patterns and shapes, making it nearly impossibe for two snowflakes to be exactly alike. Essentially, each snowflake's shape tells the story of its unique journey through the air.
Key points about snowflakes fall under 3 categories. These categories are unique growth patterns, humidity impact and molecular variations. Every snowflake encounters different atmospheric conditions as it falls, causing its arms and branches to develop in a distinct way. Higher humidity can lead to more complex branching patterns while low humidity results in flatter snowflakes. Even though snowflakes are made of the same basic components (hydrogen and oxygen) the slight variations in their moleular arrangement contribute to their individuality.
I think it is safe to say that most of us as a child have tried catching snowflakes with their tongue. It typically symbolizes a moment of pure, childlike joy and wonder in the midst of winter. It represents the simple pleasure of experiencing the beauty of falling snow, often associated with carefree play and embracing the cold weather.
Catching snowflakes is a childhood rite of passage. Everyone has done it, no matter their age. All you have to do is tip your head back, stick out your tongue and try to catch a snowflake in your mouth.
To take a closer look at snowflakes before they melt or join a pile on the ground, simply put a piece of black construction paper in the freezer. When it is snowing, grab your frozen sheet of paper and head outside. Once your paper is full of flakes, you can return it to the freezer to inspect later with a magnifying glass.
Have fun!
