The Water Cycle

Slide 2 - Mind map

Evaporation
When liquid water heats up, its molecules move faster, and some of the molecules near the surface break away and become a gas (water vapor) which rises in the air.
Ex: a puddle drying up or steam from a boiling pot of water

Slide 3 - Slide

Condensation
When water vapor (water as a gas) cools, the molecules slow down, condense (come together), and form liquid which are shown as clouds in the water cycle.
Ex: a cloud or drops on a cold beverage bottle

Slide 4 - Slide

Precipitation
When the liquid water molecules become dense and heavy enough, they fall from the clouds and to the ground in the form of rain, snow, sleet, etc.
Ex: a spring rain or a winter snow

Slide 5 - Slide

Collection
When the precipitation falls, it has to go somewhere, so many times the water is directed to rivers, lakes, oceans, and/or groundwater.
Ex: snow-melt runoff flowing into a stream or rain falling into the ocean.

Slide 6 - Slide

And then it restarts!
Evaporation, Condensation, Precipitation, Collection, Repeat.
Puddle water heats and turns to vapor, vapor cools and forms clouds, liquid water gets dense enough and falls as rain, rain falls into the ocean.

Slide 20 - Quiz

Remember...
We see the water cycle on a daily basis, whether it is the pond in our backyard, a cloud in the sky, a puddle drying up on a sidewalk, or a snowstorm that causes a snow day. Water is always in movement, and it always cycles back around.
