The
purpose
of
this
resource
is
to
measure
near-surface
soil
temperatures.
Students
measure
soil
temperatures
at
5
cm
and
10
cm
depths
using
a
soil
thermometer.
Students
will
be
able
to
perform
a
soil
thermometer
calibration,
carry
out
soil
temperature
measurements
accurately
and
precisely
and
record
and
report
soil
temperature
data.
Students
will
be
able
to
relate
soil
temperature
measurements
to

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.

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.
