The
Foundation
is
committed
to
providing
balanced
information
regarding
the
use
of
water
as
a
renewable
energy
resource
in
the
Northwest.
All
segments
of
the
public
have
become
increasingly
concerned
with
the
costs
and
benefits
of
operating
hydroelectric
facilities.
Environmental
impacts,
operational
issues,
economic
needs,
preservation
of
benefits
such
as
flood
control
and

This
module
on
measuring
nitrates
and
their
effects
on
water
quality
is
from
a
larger
series
on
water
quality
investigations.
It
provides
background
information
on
nitrates
and
how
it
affects
water
quality.
It
also
contains
both
a
pre-test
and
post-test,
a
laboratory
investigation,
and
a
self-study
game.
The
purpose
of
the
site
is
to
help
students
understand
the
sources
of
nitrates
and
the
role
that

The
purpose
of
this
activity
is
to
measure
relative
humidity
using
both
a
sling
psychrometer
and
a
digital
hygrometer.
Intended
outcomes
are
that
students
learn
to
quantify
humidity
and
that
there
is
a
limit
to
the
amount
of
water
vapor
that
the
air
can
hold.
Students
gain
insight
into
why
rain
drops
and
snow
flakes
form
and
why
there
is
precipitation.
Supporting
background
materials
for
both

The purpose of this resource is to measure the salinity of the water at your hydrology site. Students use a hydrometer to measure the specific gravity of the water sample, and use a thermometer to measure the temperature. With these two values, students will use tables to determine the salinity.

The
purpose
of
this
resource
is
to
log
soil
data
using
a
Davis
soil
moisture
and
temperature
station.
Soil
moisture
and
temperature
sensors
are
installed
at
multiple
depths
and
a
station
is
set
up
to
measure
and
record
measurements
at
15
minute
intervals.
These
measurements
are
transferred
to
your
school.s
computer
and
then
submitted
to
GLOBE
via
email
data
entry.

The
purpose
of
this
resource
is
to
sure
the
distribution
of
different
sizes
of
soil
particles
in
each
horizon
of
a
soil
profile.
Using
dry,
sieved
soil
from
a
horizon,
students
mix
the
soil
with
water
and
a
dispersing
solution
to
completely
separate
the
particles
from
each
other.
Students
shake
the
mixture
to
fully
suspend
the
soil
in
the
water.
The
soil
particles
are
then
allowed
to
settle
out

The purpose of this activity is to measure surface temperature with a handheld Infrared Thermometer (IRT). The instrument is pointed at the ground to take surface temperature readings. Intended outcomes are that students will learn to use an infrared thermometer, and understand how different surfaces radiate energy. Supporting background materials for both student and teacher are included.

In
this
module,
students
carry
out
a
number
of
activities
that
demonstrate
the
concepts
of
evaporation,
condensation,
precipitation,
and
soil
moisture
and
runoff.
The
students
then
construct
a
terrarium
as
a
way
to
observe
the
water
cycle
as
a
whole.
Immediately
following
this,
students
use
the
Internet
to
acquire
Real
Time
Data
from
the
Olympic
Peninsula
in
Washington
which
they
can
then
use
to
