Six sided crystals
• Snowflakes are all six sided because of their chemistry
• Snowflakes are made of water molecules• Water molecules are “polar” – they have an
electrical charge• The charge makes the molecules look like

Power of Three
• Three water molecules that stick together form the base of the snowflake
• These keep adding more until it gets so heavy it falls to the ground
Avalanche!
• Snow is very heavy• When snow piles up, it can fall in an avalanche• Avalanches can be very dangerous, so watch
out for warning signs in mountainous areas
