The
National
Atmospheric
Deposition
Program
monitors
wet
atmospheric
deposition
(chemical

deposited
from
the
atmosphere
via
rain,
sleet
and
snow)
at
over
220
National
Trends
Network
sites
throughout
the
United
States.

The purpose of this resource is to measure the amount of oxygen dissolved in water. Students use a dissolved oxygen kit or meter to measure the dissolved oxygen in the water at their hydrology site. The exact procedure depends on the instructions in the dissolved oxygen kit or meter used. The meter requires calibration before use.

The purpose of this resource is to measure the water content of soil based on the electrical resistance of soil moisture sensors. Students install soil moisture sensors in holes that are 10 cm, 30 cm, 60 cm, and 90 cm deep. They take daily readings of soil moisture data by connecting a meter to the sensors and using a calibration curve to determine the soil water content at each depth.

The
purpose
of
this
activity
is
to
measure
ozone
concentrations
at
ground
level.
Students
deploy
a
strip
of
paper
that
changes
color
in
the
presence
of
ozone.
They
use
an
ozone
reader
to
determine
the
amount
of
ozone
in
ppb
as
indicated
by
the
color
change
of
the
paper
strip.
Intended
outcomes
are
that
students
will
learn
to
measure
the
concentrations
of
ground-level
ozone
in
the
atmosphere
and

The
purpose
of
this
activity
is
to
determine
the
amount
of
moisture
input
to
the
local
environment
by
measuring
rain
and
snowfall
and
to
measure
the
pH
of
precipitation.
To
do
so
students
use
a
rain
gauge
and
a
snowboard
to
measure
the
daily
amount
of
precipitation.
Special
pH
measuring
techniques
for
precipitation
are
used
to
determine
the
pH
of
rain
and
melted
snow.
Intended
outcomes
are
that

The
GLOBE
Cave
Protocol
Field
Guide
utilizes
existing
GLOBE
protocols
to
explore
an
extreme
environment.
Caves
provide
an
opportunity
to
utilize
GLOBE
protocols
to
investigate
underground
environments
and
compare
them
to
surface
environments.
Outside
the
cave,
students
record
elevation,
MUC,
latitude
and
longitude,
air
temperature,
relative
humidity
and
air
pressure.
Inside

The
purpose
of
this
resource
is
to
understand
that
soil,
under
different
environmental
conditions,
plays
a
role
in
the
decomposition
of
organic
materials.
Students
use
bottle
experiments
to
observe
changes
in
the
decomposition
of
vegetable
scraps.
Students
vary
temperature,
moisture,
and
light
conditions
to
determine
the
conditions
that
best
facilitate
the
decomposition
of
organic
material
in
soil.
