In
this
resource,
students
will
discover
that
there
are
notable
differences
between
sea
ice
and
fresh-water
ice,
such
as
density.
In
on
segment,
students
learn
that
the
first
sign
of
freezing
on
the
sea
is
an
oily
appearance
of
the
water
caused
by
the
formation
of
needle-like
crystals.
The
site
explains
the
relationship
between
growth
and
the
rate
at
which
heat
flows
from
the
water
and
that

In this activity, students will discuss the potential correlation between the thickness of sea ice and the thickness of the snow cover. They will use graphing calculators to graph data acquired in the field about the thickness of sea ice and snow and then interpret the graphs to determine the relationship between snow thickness and sea ice thickness.

Launched
by
the
National
Snow
and
Ice
Data
Center,
the
"All
About
Sea
Ice"
website
is
designed
as
an
introduction
to
sea
ice:
what
it
is,
how
it
forms,
how
it
is
studied,
how
it
affected
historical
expeditions
in
the
polar
regions,
and
what
role
it
plays
in
the
global
climate.
The
site
contains
over
80
pages
of
information
on
sea
ice,
including
a
glossary
of
sea
ice
terms
and
links
to
more
information.

The
sea
ice
around
Antarctica
grows
dramatically
from
late
February,
when
large
parts
of
the
coast
are
ice-free,
to
October,
when
the
amount
of
sea
ice
effectively
doubles
the
size
of
the
continent.
The
SeaWinds
Scatterometer
instrument
on
the
QuikSCAT
satellite
captures
this
dramatic
ebb
and
flow
and
shows
the
sea
ice
as
dynamic
and
always
moving,
even
in
areas
that
are
ice-bound.

This video segment, adapted from a NOVA broadcast, shows how sea ice forms in the Southern Ocean around Antarctica and how its seasonal fluctuation dramatically changes the continent. The segment, two minutes thirty-five seconds in length, includes rare footage of the destruction of the British ship 'Endurance', trapped and crushed by sea ice in 1914.

In
this
exercise,
students
observe
simulations
of
melting
sea
ice
and
a
melting
continental
ice
sheet
in
order
to
investigate
the
relationship
between
the
melting
of
the
ice
and
the
water
level
in
the
tank.
The
water
tanks
simulate
the

In
the
first
example,
the
ice
is
floating
in
water.
This
would
be
