The purpose of this resource is to measure soil water content by mass. Students collect soil samples with a trowel or auger and weigh them, dry them, and then weigh them again. The soil water content is determined by calculating the difference between the wet sample mass and the dry sample mass.

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

is
to
introduct
details
on
how
to
use
digital
soil
thermometers.
A
digital
thermometer
is
used
to
measure
current
temperatures
as
well
as
daily
minimum
and
maximum
temperatures.
One
temperature
probe
is
placed
at
a
depth
of
5
cm
in
the
soil
while
another
is
installed
at
a
50
cm
depth.
The

are
stored
by
the
instrument
for

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

Special
pH
measuring
techniques
for
precipitation
are
used
to
determine

soil
profile.
Students
identify
the

soil
characterization
site,
then
measure

The purpose of this resource is to measure the pH of a soil horizon. Students mix dried and sieved soil samples with distilled water. The mixture is allowed to settle until a relatively clear layer is formed. Students use a pH pen, pH meter, or pH paper to determine the pH of the sample. The procedure is done three times for each horizon.
