In
this
activity
students
will
search
the
Web
in
order
to
answer
specific
questions
about
the
salinity
of
oceans.
They
will
then
create
a
visual
presentation
of
their
findings,
using
pie
charts
illustrating
the
chemical
composition
of
the
ocean,
or
line
graphs
of
the
three
major
oceans
showing
seasonal
salinity
readings,
or
a
comparison
of
the
salinity
of
each
of
the
oceans.

In this lesson, students become familiar with how ocean water forms density-stratified layers in many places. They design and carry out a series of tests to show how water masses of four different densities interact, using clear straws to stack colored water of different salinities. Temperature is varied to increase the differences in density of each water sample.

Network
(or
SALMON)
project,
which
aims
to
predict

in
Prince

offshore
southern
Alaska.
The
goal
is
to
place
a
host
of
scientific
instruments
into
the
Sound
that
would
track
in
real
time
such
things
as
ocean
currents,
temperature
and

This
lesson
on
the
cause
of
currents
and
water
circulation
in
the
Arctic
Ocean
will
require
students
to
investigate
the
influence
of
salinity
and
temperature
on
the
density
of
seawater
to
determine
what
factors
drive
water
circulation
in
the
Arctic
Ocean.
Students
identify
the
primary
driving
forces
for
ocean
currents
and
infer
the
type
of
water
circulation
to
be
expected
in
the

In
this
lesson,
students
will
discover
the
basics
of
the
methane-based
chemosynthetic
processes
and
learn
how
organisms
in
cold
seep
communities
obtain
energy
from
methane.
As
they
proceed,
they
should
be
able
to
define
the
process
of
chemosynthesis,
and
contrast
this
process
with
photosynthesis.
Students
will
also
explain
the
process
of
methane-based
chemosynthesis
and
explain
the
relevance
of
chemosynthesis

In
this
lesson
students
will
discover
the
relative

content
of
light
hydrocarbons
that
might
serve
as
substrates
for
chemosynthesis
in
deep-water
coral
communities.
They
will
compare
and
contrast
photosynthesis
and
chemosynthesis
as
processes
that
provide
energy
to
biological
communities.
Given
information
on
the
molecular

This
activity
demonstrates
to
students
how
water
temperature
and
the
concentration
of
dissolved
and
suspended
solids
affect
the
density
of
sea
water.
They
will
use
various
materials,
such
as
salt
and
food
coloring,
to
create
and
test
water
of
different
densities
and
record
the
time
it
takes
drops
of
different
water
to
sink
through
a
mineral
oil
cylinder.
In
