In
this
activity,
students
will
analyze
their
nitrogen
oxide
emissions
from
all
sources
(including
coal-fired
power
plants,
natural
gas
combustion,
gas-powered
lawnmowers,
etc.)
and
combine
them
with
vehicle
emissions
calculated
in
the
previous
activity
(Ground-level
Ozone:
Your
Vehicle)
to
derive
an
estimate
of
total
emissions
of
smog-forming
NOx.
They
will
use
an
online
nitrogen

Due
to
the
presence
of
dissolved
gases
such
as
carbon
dioxide,
rainfall
is
naturally
acidic.
The
release
of
other
gases
and
chemicals
such
as
sulfur
dioxide
during
the
combustion
of
coal
and
oil
can
cause
rainfall
to
become
even
more
acidic,
sometimes
to
the
point
of
toxicity.
In
this
activity,
students
will
measure
the
pH
of
local
rainfall
to
see
what
effect
these
gases
have
in
their
region.

The
amount
of
carbon
dioxide
in
the
atmosphere
has
been
increasing
for
many
decades
now,
mostly
due
to
the
burning
of
fossil
fuels
by
mankind.
In
this
exercise,
students
will
track
their
daily
activities,
and
and
estimate
how
much
carbon
dioxide
they
are
responsible
for
emitting
with
the
use
of
an
online
Personal
Greenhouse
Gas
Calculator
developed
by
the
U.S.
Environmental
Protection
Agency
(EPA).

This
lesson
provides
an
introduction
to
the
use
of
coal
as
an
energy
source.
Topics
include
the
history
of
coal
usage,
applications
of
coal
as
an
energy
source,
and
major
suppliers
of
coal
(the
United
States).
There
is
also
discussion
of
how
coal
is
created,
located,
and
produced,
and
technologies
for
burning
it
more
cleanly.
The
lesson
includes
a
hands-on
activity
in
which

This
two-part
activity
provides
an
introduction
to
the
basics
of
measurement
(linear,
mass,
volume,
density)
and
discusses
the
role
of
inferential
statistics
in
comparing
any
two
measurements.
The
concept
of
random
variations
in
measurements
is
introduced,
which
leads
to
a
discussion
of
binomial
distributions
and
probability
in
comparing
measurements
and
results.
Students
will
use
online
databases

In
this
activity,
students
quantify
and
analyze
their
personal
contributions
of
smog-forming
compounds
due
to
driving.
The
activity
builds
upon
the
previous
lesson
(Ground-Level
Ozone).
The
students
will
review
online
materials
on
vehicle
emissions
and
use
an
environmental
calculator
produced
by
Environmental
Defense
to
examine
their
individual
emissions
of
ozone-forming
compounds.
They

Discussion
of
holes
in
the
stratospheric
ozone
layer
usually
revolves
around
investigations
of
the
thickness
of
the
layer
near
the
South
Pole.
This
online
activity
allows
users
to
study
the
thickness
of
the
ozone
layer
over
any
location
on
Earth
to
see
how
it
has
changed
over
time.
This
is
done
by
plotting
historical
data
from
the
Total
Ozone
Mapping
Spectrometer
(TOMS)
Program,

Soil
is
essential
for
life
on
Earth.
It
is
needed
for
food,
air,
clothing
and
so
much
more.
Discussion
topics
include
the
terms
'soil',
'dirt',
and
'sediment',
factors
affecting
the
formation
of
soils,
soil
horizons,
and
the
twelve
orders
of
soils.
In
a
hands-on
activity,
students
will
collect
soil
samples
from
three
different
locations,
use
