Snowflakes
Oh the wonderful gift of snowflakes! You can catch them on your tongue, build cute little men, and so much more! Though while you are enjoying yourself with them, you may not think about all the science going into one little drop of white fluff.
Bye!

How Are They Made?
Goodbye, Snowflakes!
To conclude, the snowflakes had said goodbye, their awesome facts have melted on your tongue, but hopefully will last in your brain. I hope you enjoyed this presentation. Snowflakes are a wonderful phenomenon, so next time it's snowing outside, don't stay inside, come out to explore. Snowflakes are fabulous!!!

Appearance

• The world’s largest snowflake was 15 inches wide and 8 inches thick. This snowflake was found on January 28, 1887.
• An average snowflake falls at about a speed of 3.1 miles per hour.
• Each winter, about 1,000,000,000,000,000,000,000,000 snow crystals drop from the sky each winter
• It takes about a million little droplets to make one snowflake.

Falling, Falling, Brr...
Snowflakes are a cold weather phenomenon formed from water vapor that condenses around a tiny particle called the seed crystal, which is usually a speck of dust of pollen in the clouds. Cloud droplets condense around the seed crystal and then freeze on the surface of the particle. The patterns you see when you look closely emerge as vapor freezes onto the primary crystal, building the new crystals, which are the six arms. People often mistake snowflakes as frozen raindrops. Frozen raindrops are sleet, not snowflakes. Snowflakes are crystals that are formed when water vapor freezes, so they wouldn’t be classified as frozen raindrops.
Snowflakes always have six sides, or else they are not snowflakes. Both the form and shape of a snowflake depends on the temperature and moisture content of the cloud. Snowflakes can be categorized into six main types: Plate (flat), column, stars, dendrite, lacy, needle, and capped column. Snow is actually clear and has no color. They reflect white from the sun, which is what gives them their white appearance.
