The Steps Involved

• Evaporation and Transpiration• Condensation (Clouds)• Precipitation• Back to the beginning!

How does the sun help in this process?

• It is warm!• What happens when

its warm after it rains?

What is Evaporation?

• Liquid becomes gas and rises up into the atmosphere!

• Where can this happen?– Lakes– Rivers– Oceans– Streams– Anywhere there is Liquid!

Want to test this out?

• Ask your parents• Fill up a cup with water• Put it outside on a Warm sunny day!• Check it every little while and tell the class

what happened!• Example of how it works!

But wait! Water can get into the atmosphere another way too!

• Transpiration• Plants absorb water• Some of this water is evaporated off of leaves

The next step is Condensation!

• Water in the Atmosphere begins to turn into a liquid– It becomes suspended in air– This is known as a cloud

Have any of you been close to a cloud before? How does it feel?

• Planes• Fog– Low cloud– Feels warm and wet

The next step is Precipitation

• Different forms of liquid begin to fall to earth

• These include:– Snow– Hail– Rain

Water can collect in various places

• This also includes “run off”• Water flows down a hill or slope into any

body of water

Groundwater

• Water can soak into the ground• It then can travel to any body of water

Ways to save water?

• Get with a partner and make a list of ways you can save water and we will share it with the class!

The End!
