Environmental Science - 12

8:00 - Opening:

Please open your chromies and REVIEW how small , medium (Gig Harbor) & large (Seattle) communities typically deal with sewage treatment.

You should have a general familiarity with primary, secondary and tertiary treatment options

SESSION #1: Gig Harbor Wastewater Treatment Plant Field Trip (8:30 - 11:30)

(*) 8:15 - 8:40 Discussion

(*) 8:40 - 9:00 Walk to GHWWTP

(*) 9:00 - 11:00 Tour Plant

(*) 11:00 - 11:20 Walk back to GHHS

LUNCH: 11:45 - 12:15

CTE W/Pictures (12:15 - 1:00)

Please take an old National Geographic (at lest 25 years old!) and find a series of pictures that outlines your interest in SOME field of environmental science.

Now please take a few moments to desribe how that field has changed in the last 25 years.

Would you be more or less likely to want to work in that field now or 25 years ago

Let's discuss

SESSION #2: (1:00 - 2:00)

OPENING QUESTION: How are the following graphics related?





  • Temperature
  • Energy Budget
  • Greenhouse Effect
  • Reservoir ("Storage Place")

LEARNING TARGET: I will be able to explain how carbon moves through the Earth's ecosystems during today's class.


Let's take a look at THIS data from NASA:

Work with your group to make a statement summarizing the data on this graph

Now let's spend a bit of time exploring how carbon moves in and out of the environment

Before we do that, let's take a quick gander at this tounge-in-cheek view of CARBON

Understanding how carbon (and not JUST CO2) moves in and out of the environment is really important, so let's work on doing an analysis to help us do just that.

Take a look at that image and WITHOUT talking to your group quite yet, write down two or three statements that come to mind on the strips that I passed out.

Also write down at least one question that comes to mind on a separate strip.

Now organize your statement strips and your question strips on your desk.

Work with your group to answer/address the questions first. We'll talk about any remaining questions with the entire class (we'll post them on the board so everyone can see them)

Now please *sort* the statement strips and we'll put the topmost statement from each group on the board too!


That graphic is sometimes referred to as an analysis of carbon flux.

Please have a conversation in your group and make a suggestion to define "carbon flux"


Understanding how carbon moves in and out the environment is really important.

Take a look at the graphic and notice descriptions of carbon in WHITE font. What is unique about that carbon?


Carbon figures in white font are reservoirs (storage places) for carbon. That means that a certain amount of carbon just stays in those places and doesn't move in and out of that environment.


If time permits, let's begin our NUMERICAL analysis of the billions of tons ("gigatons") of carbon move between:

  • Earth & Air
  • Earth & Water
