Wally was born in a big dark rain cloud in the sky. One day, Wally went on an adventure with his particle pal Paul! They had so much fun in the freezing cold temperature they got stuck together and fell from the cloud! 

As Wally fell from his cloud, he started to feel something change. He was no longer his liquid, molecular self anymore! He was now cold and solid....a snowflake!

Wally didn't fall for long before he came to rest atop and beautiful white mountain. He noticed the mountain was covered in more of his kind. Wally landed next to another snowflake named Sue. 

Slightly startled, Wally said, "Wow! Where am I?"

Sue responded, "Hi! I'm Sue! You just landed on Sugar Mountain!"

Wally, frozen with confusion asked, "What? What am I? What happened to me?"

Sue replied, "You're a snowflake of course! What happened was you were a water droplet in that cloud up there and you must have gotten really, really cold and froze to dust particle. The two of you together created an ice crystal and fell to the ground as a snowflake. This is called precipitation And here you are!"

Wally gave a little shiver and said, "Wow, that was an adventure. Thank you for explaining that to me!"

As time passed, Wally learned so much from Sue and they quickly became best friends! 

Suddenly, Wally started to feel something new.... a different sensation and again he was confused.

What Wally was feeling was the warmth of the sun.

"Oh no!" Wally screamed, "What's happening now?"

Sue replied, "Don't worry Wally! That's just the sun. It's going to warm us up with its solar radiation and send us on another adventure. Don't worry! I'll be with you the whole time!"

As Wally started to see his snowflake arms disappear and his body turn back into his familiar water drop, Sue explained this process to him.

Water drops form in clouds and the drops sometimes get cold and turn into snowflakes. When those snowflakes land on mountain tops they can get exposed to the warm sun and start to melt. When they melt the join together like molecules and flow down the mountain side and runs off into a lake or river. Rivers then flow back into the ocean and start the process all over again.
