The Water Cycle

 

Weather conditions change from day to day. To understand the relationship of clouds to rain and snow the learner will observe the process of recycled water within a closed system.
 

I. Types of precipitation
II. Evaporation forming clouds
III. Condensation
IV. Evaporation

 

 

 

Goal:

To enable students to demonstrate the process of science by posing questions and investigating phenomena through language, methods and instruments of science

Descriptions and comparisons may be presented in terms of number, shape, texture, size, weight, color, and motion.

 

Instruction

Think about the last time we saw it rain. What did the rain form? (Puddles) In a day or two, were those puddles still there? Where did the water go? When the rain goes into the air and up into the sky we say it evaporates. What does it form? Clouds are made up of all the drops of water that evaporated from the ground. What do you think would happen when a cloud gets heavy with water? What happens when you pick up something too heavy? So a cloud drops some of the water when it gets too heavy. When these clouds get heavy and the drops of water fall to the ground, what does it form on the ground for you to step in? (Puddles) In a few days what will happen to those puddles? (Evaporate)

 

Closing Questions

What causes it to rain?
Where does the water in the puddles go?

Is water used over and over?
