The
purpose
of
this
resource
is
to
understand
that
variations
in
landscape
can
affect
soil
properties.
Students
investigate
variations
in
the
soils
around
their
school
to
discover
that
soil
properties
like
moisture
and
temperature
exhibit
considerable
variability
across
a
single
landscape.
They
also
identify
factors
such
as
slope,
shade,
plants,
compaction,
which
affect
the
appearance
of
soils
and

The
purpose
of
this
resource
is
to
develop
an
understanding
of
some
of
the
relationships
between
soils
of
different
types
and
water.
Students
will
time
the
flow
of
water
through
soils
with
different
properties
and
measure
the
amount
of
water
held
in
these
soils.
They
will
also
experiment
with
the
filtering
ability
of
soils
by
testing
the
pH
of
the
water
before
and
after
it
passes
through
the
soil

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.
