Cryosphere, Elementary (K-4)
With air, land, living things and water, too.
On a globe, two circles outline their spaces.
Antarctica is a continent. The Arctic, it is not.
North and South poles are magnetic.
On a globe each pole is just a dot.
Earth's poles have polar ice caps.
No, not some kind of polar hats.
If you look you can see them on polar maps.
Now take your time.
And read this rhyme.
About Earth's polar water.
In the sea, air and on the ground.
Fluffy clouds up in the sky.
How did water get up so high?
Polar water changes states.
It freezes, melts and evaporates.
From solid to liquid to gas and back.
This cycle has a name. Is it Jack?
Arctic rivers freeze or run.
Polar bears on ice packs sun.
Polar oceans, ice and snow.
Is drifting ice a berg or floe?
On polar land, the water's fresh.
The seas are salty, what fish like best.
The Arctic sun warms the frozen ground.
But does permafrost stay around?
Down in the Antarctic, seals on a rocky beach.
Penguins in icy water, swimming out of reach.
Out in the polar oceans, whales come and go.
Sprays of water in the air. Was that a whale hole blow?
Some wonder if it will it last.
Antarctic ice sheets break.
Floating icebergs the pieces make.
In the Arctic sea ice floes.
Melt in summer, in winter grow.
All of us having to think once or twice.
Will polar water be changed by changing polar ice?
Polar Water Essential Questions:
With the support of NASA and in recognition and celebration of the International Polar Year (IPY) 2007-2008, this and other ESSEA modules focusing on polar topics have been created in hopes of increasing the awareness, understanding and interest of school-age children in polar conditions and research.
