Snowflake

Imagine a tiny, sparkly jewel falling from the sky! That's a snowflake. It's actually a single ice crystal, super small, that's big enough to float down as snow. Even though ice is clear, snow looks white because of how the light bounces off all the tiny flat sides of the ice crystals. It's like a million tiny mirrors working together!

Every snowflake starts its journey around a tiny speck, like a speck of dust, called a nucleus. Water droplets in the clouds freeze onto this speck, slowly building up into a crystal. As the snowflake tumbles through different cold and steamy parts of the sky, it picks up more water and grows into amazing shapes. It's like a tiny sculptor at work!

Have you ever looked closely at snowflakes? They are all unique! As a snowflake travels through the clouds, it meets different temperatures and amounts of moisture. These changes make it grow in special ways. Sometimes, two snowflakes might even bump into each other and stick together, making an even bigger, more unusual shape. It's a surprise every time!

Scientists have found that snowflakes can be sorted into about eight main groups, with lots of different kinds within those groups. The basic shapes that ice crystals can start as are like needles, columns, flat plates, or even fuzzy bits called rime. These simple shapes then combine and grow into the beautiful, complex patterns we see falling from the sky.
