Wally journey in water cycle
In a forest called Greenville, the adventurous young bear named Wally who loved exploring the wonders of nature.
One day, Wally took out two ice cubes and put them on the table.
He picked up an ice cube and bring it to the garden. “Oops, I dropped it!”, Wally said.
Because it was a sunny day, as time passed, the ice disappeared, leaving only a small puddle of water.
Wally found that the small puddle had disappeared in no time. He wondered where the ice and the water had gone.
He looked up information about the question in the book.
Ice (solid) The change of state is Water a physical change. (liquid) Adding heat or energy can cause ice (solid) to Water vapour melt to form water (gas) (liquid). If adding more heat, water (liquid) can change to water vapour (gas). He found the information about the change statesofmatterinthe book.
We found the change The water cycle shows states of matter in movement of water nature such as water between the Earth cycle. and atmosphere. “ I have to go out and explore the water cycle!! ”, Wally said.
Then, Wally go outside and was sitting next to the river. He found the river water seemed to change its form over and over again. Intrigued, he decided to investigate further.
EVAPORATION Wally's journey into the world of the water cycle began. He saw water change to water vapour rising into the sky. This was the first stage of the water cycle called \"evaporation\".
He saw the clouds in the sky. “It's condensation!!” Wally thought, remembering what he had read about the water cycle.
CONDENSATION The water vapour in the atmosphere had cooled down and changed back into tiny water droplets, this step called “condensation”.
The particles, such as dust, pollutants, are called condensation nuclei. Enough water vapour condenses on them to form a cloud, a large collection of tiny water droplets or ice crystals. The droplets are so small and light that they can float in the air.
The clouds take up more and more water droplets, they grew bigger and heavier. Eventually, water droplets get heavy enough to overcome the force of the surrounding air around them. Suddenly, raindrops begin to fall!
PRECIPITATION Water fall from the clouds as rain, called “precipitation”. It’s the connection in the water cycle between atmospheric water and the water on the Earth .
Wally watched in awe as the raindrops hit the ground and formed puddles near the riverbank. Some of them drop into the river.
PRECIPITATION SNOW SLEET HAIL Sometimes, instead of rain, snow form in the cloud and fall down when the air temperature was below freezing. When the raindrops fall and freeze on the way down become to form sleet. Incaseofhail, it form in the cloud when the ice flake create the ball of ice. Wallythoughtaboutthe bookthathehadread.
FREEZING/ SOLIDIFICATION In winter, it snows instead of rain. And water in the rivers turned to be the ice on the surface of river when the temperature below freezing point. (0 degreeCelsius).
MELTING When the air temperature rise above freezing, the river ice and snow began melt to the water, called “melting”.
“How about the desert? It has no water reservoir as river, lake or the ocean. How will the water cycle happen?”, Wally thought. He was curious and went to see his teacher, Mr. Owl .
Good morning Mr.Owl, I have some questions to ask you. How will the water cycle happen in the desert? couldyouexplain tome?
The desert is the land of “evapotranspiration”. In the desert, plants release water through the stoma, the tiny pores in their leaves or stem in cactus via transpiration. The water change to the water vapour via evaporation , adding water vapour to the air. It rises up and become to the watervapourintheatmosphere.
Then the water cycle in the desert begin!! Underground Groundwater
Wow!!! The water cycle is like a never- ending adventure.
Wally understood the water cycle like never before and shared the story with children in the village and became the \"Water Expert\" of Greenville.
