The
purpose
of
this
resource
is
to
identify
a
reqion
for
study
as
a
system,
and
to
establish
a
list
of
characteristics
and
features
useful
for
determining
the
boundaries
of
regional
systems.
Students
discuss
their
current
understanding
of
what
Earth
systems
are
and
how
they
work,
and
consider
how
to
identify
the
boundaries
of
a
region
for
Earth
system
study.
In
small
groups,
they
select
a
region

The
purpose
of
this
resource
is
to
develop
an
understanding
of
how
water
flows
through
different
soils
and
how
it
is
transformed
when
it
flows
through
these
soils.
Students
time
the
flow
of
water
through
different
soils
and
observe
the
amount
of
water
held
and
also
the
filtering
ability
of
the
soils.
They
will
also
observe
the
filtering
ability
of
soils
by
noting
the
clarity
of
the
water
before

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
purpose
of
this
resource
is
to
identify
specifically
how
one's
own
region
is
connected
with
others,
and
to
discover
the
interconnected
nature
of
the
Earth's
regions
as
systems.
Students
brainstorm
about
the
nature
of
connections
between
their
region
and
others,
across
oceans
and
on
different
continents.
On
a
black-line
map
of
the
world,
they
trace
possible
pathways
of
water
and
wind
currents
from

is
to
develop
the
best
possible
representation
of
the

Students
visit
a
study
site,
where
they
observe
and
recall
their
existing
knowledge
of
air,
water,
soil,
and
living
things
to
make
a
list
of
interconnections
among
the
four
Earth
system
components.
They

The
purpose

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.
