Serious about science since….first grade

You might not see a single thing around you. You’re not alone.

The You Tube® video Once Upon a Tide presents a dif­fer­ent kind of fairy tale.

Lis­ten­ing to the sound a seashell makes, a real liv­ing girl enters into a sad and beau­ti­ful car­toon world of the ocean.  The sto­ry­teller in the video says, “you might find it hard to believe but I assure you it’s true.”

You see under­wa­ter that there is a huge world we do not know much about.  The oceans have pop­u­la­tions of dif­fer­ent ani­mals, loca­tions, light, its own kind of envi­ron­ment.  It is dif­fer­ent than what we human live above ground.  But what we do on land and how we behave directly affects the oceans.  And what goes on in the oceans directly affects the weather.  Which then directly affects us humans on land.  So if the oceans suf­fer, so will we.

Oceans cover more of the earth’s sur­face than rocks and dirt do.  When you look at a map of the world, notice how much water there is, com­pared to the land.

Oceans are very deep.  The lower you go into the water, the darker it gets because the sun­light from above can no longer penetrate.

Morn­ing Earth explains:

Life in the ocean that lives below the sun­light pen­e­tra­tion lives in a three dimen­sional black­ness. They can move in any dimen­sion, but have few clues about where because there are zero land­marks, or bet­ter, signs to tell them where they are. It is hard for gravity-bound beings like us to imag­ine free float­ing all the time. No autotrophs (self-feeders) live here–there is no light to photosynthesize.

When we scuba dive to explore this com­plex world, we are lim­ited by our bod­ies, even if we have very good oxy­gen tanks to breath.  We expe­ri­ence lim­its that we don’t have when we’re out of the water.  The lower we swim down and down into the ocean, the more our bod­ies feel pres­sure on our organs.  And at some point our bod­ies sim­ply can­not dive lower because the pres­sure is too much.

So, sci­en­tists employ other meth­ods to go fur­ther down to explore, using robots and sub­marines with cam­eras, and are able to find the small­est of organ­isms that you can­not see with­out the help of a micro­scope.  You might take a look at drops of water taken from these depths and not be able to see any­thing with just your eyes.  Look at the water using  a micro­scope, and you will truly see life where you could not see it before.

I bet you have never thought of a fairy tale as a micro­scope before, right?

The story of water: moving, changing but not going away!

Just like being stuck with your pest of a brother or sis­ter, you can’t get away from water.  But you should be glad you can’t.  On both accounts.

You see water in a lake, or a stream, or river — you get the idea.  Humans, ani­mals and plants drink the water up.

What we don’t drink evap­o­rates.  Or it freezes.  Some of it melts.  It goes up to the clouds that hold water until they release the water and then water has returned. You might think to your­self, “Not as good as grape juice” … until you’re really thirsty and there’s a fresh glass of water nearby.  That stuff sit­ting in the glass?  It’s always leav­ing and com­ing back.  You might not think about it that way.

Sci­ence with Me explains,

Water can change state from liq­uid to vapour to ice at dif­fer­ent places on the water cycle. How­ever, the bal­ance (or amount) of water always stays the same. So the water in your glass is very, very, very old indeed! (but it still tastes good). If you think of a per­son who lived hun­dreds of years ago, well the water in your glass was on the Earth then too! Maybe they even drank the same water as you…ewwwww!!

Sure, it might take a long time for the water in Lake Char­gog­g­a­gog­gman­chaug­g­a­gog­gchaubuna­gunga­maugg to evap­o­rate, tran­spi­rate, con­den­sate, pre­cip­i­tate, hes­i­tate, stare at Nate.

And sure, it might be a long time before your brother, both­er­ing you with his pile of legos, can build a robot that will pour some­thing into a glass for you.  It might be some time later when your sis­ter, buzzing all the time at the game of Oper­a­tion, can safely per­form the Heim­lich maneu­ver on you because you drank too fast and started chok­ing.  Then it’s a good thing they didn’t go away.  Maybe it would help to con­sider your brother or sis­ter as a slow mov­ing ice­berg, a frozen body of water.  That’s not my sis­ter.  That’s just vapor.

Solid, liquid, elephant, iguana

When sci­en­tists talk about ‘chang­ing states’ they do not mean mov­ing from Iowa to Ken­tucky, or New York to Philadel­phia. They do not mean the state of an ele­phant ver­sus the state of an iguana. Click the link below to play a game to learn more about chang­ing states.

Can you cool water down and heat up water here??
