What Makes Rain?

Students drew the water cycle, placed H2O in the bag. Now time to observe

H2O

The recipe          

for water is the same as          

it’s always been:  two parts          

hydrogen one part          

oxygen.  Two-to-one          

that’s the rule to make a water

What Makes Rain?

Condensation: Water vapor cools as it rises, and tiny drops of water form clouds.

Evaporation:Water evaporates from the lake and changes to water vapor.

Precipitation: The water gets too heavy for the clouds and falls as rain or snow.

 Water Cycle

Water Cycle

Accumulation: Water on the ground flows back to the lake through the rivers and streams.
