WEATHER DATA: 8:00 - 8:15

SESSION #1: Planet Earth Energy Budget (8:15 - 9:30)

OPENING QUESTION: We have analyzed this data several times. Last Thursday (I think), I asked you what would happen if this "Energy Budget" was just a little bit off. That is, what would happen if the Earth held on to just a little more energy than it gave off to space.

My question for you today is what might cause such a situation to occur?

xxxx

WORDS OF THE SESSION:

  • Temperature
  • Energy Budget
  • Greenhouse Effect

WORK OF THE SESSION:

Notice that the term of this session is "energy budget" -- how does that term apply to that image?

Now let's imagine that "energy budget" is out of sync by just a tiny bit. In otherwords, the Earth gives off just a tiny bit more energy back to space than it absorbs from the sun every day.

What migth cause such a process to occur?

Now let's imagine that "energy budget" is out of sync by just a tiny bit. In otherwords, the Earth absorbs just a tiny bit more energy than it emits back to space every day.

What migth cause such a process to occur?

Now let's revisit THIS image from this morning:

fffss

We discussed water as being a critical need for human beings to survive and thrive, but we also briefly discussed energy.

From what you know about how human beings consume energy, what possible impact does that graph above suggest?

What are energy sources that supply energy for our homes here in Western Washington? Shout 'em out, we'll make a list

 

 

Now let's check that list against THIS:

What *seems* to be wrong with that data?

Surprised? (Let's do a quick check of images/graphs and see if we can find electricity generation data that is more current than 2010.

 

Now let's repeat that task for the US:

What is the common factor for MOST of that power generation?

 

 

BURNING!

2015 Data:

 

Has anyone taken chemistry? What is the chemical equation for a combustion reaction?

Virtually every time we BURN something we combine some form of hydrocarbon with oxygen like this:

CxHy + O2 => CO2 + H2O

where x and y are integers since there are so many different types of hydrocarbons. For example:

methane = CH4

propane = C3H8

What does that mean?

Now please work with your group to make a statement that summarizes methane production and carbon dioxide output shown in the following graphs...

How do we know that?

Let's take a look

SESSION #2: Natural Resources - Water (9:30 - 11:00)

OPENING QUESTION:

Let's revisit THIS data:

fffss

Please have a conversation with your group on how that data suggests our water use will change in:

Gig Harbor

Seattle

The entire US

LEARNING TARGET: I will be able to list multiple ways that Gig Harbor and cities of Western Washington obtain freshwater during today's class.

WORDS OF THE SESSION:

WORK OF THE SESSION:

Where do you suppose the city of Gig Harbor gets most of its drinking water?

Oh and by the way, do we use fresh drinking water to:

    • Wash our clothing?
    • Flush our toilets?
    • Wash our driveways?

    Perhaps THIS will help (please take a look)

    Now let's take a gander at THIS... please take a few moments to SKIM the document and just look for titles and tidbits that stand out...

    Or THIS?

    HMMMM.....seems to me that divide and conquer is in order here-- split it up!

    Let's discuss

    ═══════════════════════════

How much water does the City of Gig Harbor use every day? Where does that water go?

Wait a sec, I live outside the city of Gig Harbor, where do I get my water? Where does my sewage go?

Hopefully we found the City of Gig Harbor Wastewater Treatment Plant manages over 1.6 million gallons of sewage every single day!

How does that water move in and around the City? Let's discuss

Now let's cut out yet another 3' x 3' slice of butcher paper and:

  • Sketch Gig Harbor (the actual salt water harbor) and the surrounding communities shown on THIS map:

Keeping in mind that the City of Gig Harbor gets ALL of its drinkingn water from underground wells... do you think it is practical to pump all that water into individual homes, business and schools present on that map (hint: it isn't).

So let's take a moment to learn how to read a topographical map before we continue.

Please locate the Gig Harbor Waste Water Treatment Plant (GHWWTP) on the map.

Now, after doing that, what practical ways might we have to move water around the City of Gig Harbor.

Now let's sketch those...

  • Working with your group AND that topographical map, various main housing areas
  • Working with your group AND that topographical map, sketch main business areas
  • Indicate Schools present on that map
  • Working with your group AND that topographical map, sketch in BLUE water lines moving through the City of Gig Harbor (going downhill please) that connect major housing, business and school areas.
  • Working with your group AND that topographical map, sketch in BLUE sewage water lines moving through the City of Gig Harbor (going downhill please) that connect major housing, business and school areas.
BREAK: (11:00 - 11:15)

CTE & Environmental Science (11:15 - 11:45)

Option #1: Think about the topics we've discussed, the articles and/or pictures you've seen in National Geographic, Smithsonian and Scientific American magazines and the field trips that we've taken (so far!).

What sort of work ASSOCIATED with that topic do you, or do you think someone in your family might enjoy doing for a career.

  • Sketch the path that you (or your family member) might take in order to get a job in that field or a related field.
  • Now please use your chromies to find out what where you (or your family member) might go about get training for the job here in Washington State.
  • Finally, again use your chromies to find out the yearly salary that such a position pays.
LUNCH: 11:45 - 12:15
Session #3 - Natural Resources: Water (12:15 - 1:30)

Let's Continue this morning's exercises

═══════════════════════════

Now let's expand our thinking a bit.

  • How many people live in Seattle?

What happens when it breaks down? Let's read THIS for content:

  • Here are some statements that are either true or false to address as you read: 'The City of Seattle shut down the water supply when the sewage treatment plant broke down'

Now let's do just a bit of research:

1) How many people are served by the City of Seattle water supply system?

2) Where do all those people get their drinking water (HINT: It comes from several different sources)

    • Tolt River Watershed
    • Cedar River Watershed
    • Wells (mostly for backup)

3) How much water is processed by the City of Seattle Waste Water Treatment Plant?

If we can expect the population to increase to *about* 750,000 by 2030, where will the City of Seattle get it's water then?

What about other areas around Seattle?

 

WEATHER DATA: 1:30 - 1:45
BREAK: 1:45 - 2:00

FOSSILS (2:00 - 3:00)

Let's Review:

Perminearlization and the sponge activity (aside from the part where the smoke alarms went off (*DOH*)

Reflection: What is going well? What is frustrating?

Informal Presentations on Technique!
