Student Safety Contract Rules
* This a legal document that can be used as evidence in a court
of law. It is to be taken very seriously.
* Blue or black ink only. No pencil. No other colors.
* No changes: no erasures, no cross-outs, no white-outs. If you
make a mistake, you must get a new form and start all over again.
* Your parents must date their own signature. Do not date it for
them!
* You can not take part in lab activities if you have not turned in all
the safety documents. You will sit in the middle of the room with
goggles and apron on. You can watch your lab group from a
distance, but you may not be at the table and you may not touch
lab materials.

STAMPS
* I stamp bookwork.
* 1 stamp = 1 point at the end of a unit when you turn in your
bookwork, along with other stuff, in the form of a unit packet.
* To get stamps, work must be done on time.
* To get a stamp, you must keep your work organized enough in
your binder that you can find it quickly when I announce that I am
stamping.
* To get a stamp, you have to pay attention and get out your
work when I announce that I’m stamping.
* If you miss stamping because you’re tardy, you don’t get that
day’s worked stamped, unless you have note, of course.
* If you are absent, you must show proof of absence clearance
in order to get notes or non-math questions stamped.
* I typically allow extra time for the completion of question
sections that involve math, since even honest, sincere students
often don’t “get it” the first night it is assigned.

IONIC COMPOUND FORMULA TIPS & RULES
* Column number tells you number of valence electrons
* Metals like to lose all their valence electrons
* Metals become positive ions, nonmetals negative
* In chemical names AND formulas, positive ion comes first,
negative ion second
* Overall, compound must be neutral
* Use “criss-cross” shortcut: one element’s charge becomes the
other element’s subscript & vice versa
* See page 257 for table of polyatomic ion names & formulas
* Nonmetal gets “-ide” ending if alone, “-ite” or “-ate” if in a
polyatomic ion w/oxygen or some other element
* Roman numeral for metals tells you the positive charge
* Use parentheses for polyatomic ion if more than one of it

these be indirectly nonzero-emission?
A: Electric cars emit no fumes or
particles . . . Just noise, and not much.
However, the electricity-generating
power plants that give your home
electricity DO typically burn fossil fuels,
so they give off all kinds of air pollution.

Warm-up: How much more intense than a chainsaw is a rock
concert?

OUT OF SEAT during roll call = TARDY
Environmental Science
Tuesday 2/16/2016
Warm-up: How much more intense than
a chainsaw is a rock concert?
A: According to fig 2.4 on page 312:
Rock concert = 120 dB; Chainsaw = 100 dB
Every 10 dB diff.  10 x the intensity
120 – 100 = 20
20 / 10 = 2
102 = 10 x 10 = 100
(Show this math on scratch paper on tests!)

Maximizing your Scratch Paper Points
1. Which of the following is used to kill bacteria in treated
wastewater before it is returned to a river, lake or ocean?
A. chlorine
B. glucose
C. amino acids
D. Lard
On my bubble sheet I would pick
“A”
On my scratch paper I might write:
1. Chlorine is a poisonous gas that can kill bacteria, people, and
other living things. Glucose, a sugar, is a nutrient that can feed
bacteria. Amino acids are the building blocks of proteins. They
don’t kill bacteria, they feed them. Lard is full of fat and is very
edible, so it, too, would only feed bacteria, not kill them.
Maximizing your Scratch Paper Points
2. Which of the following would be the most appropriate choice to
include in a xeriscaped backyard?
A. jungle vines
B. rice
C. cypress trees and Spanish moss
D. cactus
On my bubble sheet I would pick
“D”
On my scratch paper I might write:
2. Xeriscaping is when you landscape your yard so that it
requires as little irrigation water as possible. Cacti are desert
plants that require very little water, so they are good xeriscaping
plants. Jungle vines grow in tropical rainforests and require too
much water. Cypress trees and Spanish moss grow in swamps.
Rice is cultivated in pond-like paddies.

A: Generally, the closer a place is to the
equator, the hotter it is, so low latitude
means high temperature. The closer to
the poles, the colder a place is, so high
latitude means low temperature.

Quiz Show Tips
* The App: The Quiz Show Lite application is already installed
on the computer lab machines, but if you want to run it from your
computer at home, you’ll need to use the link on my home page.
* Only vs. Cumulative : Quiz Show question files (files ending
with .tst) can be “only”, which means just that one chapter, or
“cumulative”, which means every chapter up to and including that
chapter . . . Though the chapter set may be based on last year’s
order rather than this year’s.
* Browsers: Quiz Show does NOT seem to work on Mozilla
Firefox, which is why I insist that you use Internet Explorer. Not
sure about Google Chrome or Apple Safari.
* Restart: Start a new quiz by shutting down Quiz Show entirely
and clicking the .tst file you want on hhscougars.org.

OUT OF SEAT during roll call = TARDY
Warm-up: What affect on Earth’s climate
does burning down tropical rain forests
have? Why?
A: Trees turn into water and
carbon dioxide when they burn, so CO2
levels rise as trees burn.
CO2 is a greenhouse gas, so more CO2
should cause global warming.
Also, when trees are alive, they remove
CO2 from the air, but dead trees don’t
photosynthesize.

Warm-up: What farming practices can keep
agriculture from being sustainable?
A: Drawing water from aquifers faster than
they fill up worsens drought.
Irrigation can cause salinization due to
evaporation and salt accumulation.
Pesticide target populations can develop
resistance pesticide becomes useless.
Plowing disrupts topsoil  erosion
Monoculture  soil depletion 
desertification
Pesticides may persist in air, water, soil.

Monsanto have to do with soybean farmers?
A: Monsanto makes an herbicide called
“Round-Up”.
Monsanto also created a Round-Up-resistant
strain of soybeans, which they patented.
In order to compete, soybean farmers must
grow Monsanto’s GMO soybeans.
If they save seeds from one of their crops
rather than buying new seeds from Monsanto,
Monsanto’s lawyers will bankrupt them with
legal action. (According to “Food, Inc.”)

Warm-up: Name a material found in
ocean water that is not found in large
amounts in fertile soil on land.
Most obvious answer: Salt
Salt kills plants by dehydration (sucking
water out of them).
“Salinization” is when salts build up in
soil, causing it to be less fertile, even
sterile.
VERY SALTY WATER
Salt ions too big to
fit through holes in
cell membrane
Less salty water
VERY SALTY WATER
Less salty water
Water molecules
small enough to fit
through holes
VERY SALTY WATER
Less salty water
Each water molecule has a chance to wander to the other side
More water molecules = more chances to lose water
More water molecules moving  higher flow rate
Water flows in both directions, but mostly from the more watery
side to the less watery side. OSMOSIS!

new DNA correctly.
Only the plant cells with the new DNA
