This
teacher-directed
demonstration
provides
a
conceptual
understanding
of
latent
heat.
Using
the
example
of
a
chemical
hand
warmer,
students
learn
about
phase
changes
from
liquid
to
solid
and
from
solid
to
liquid
and
observe
that
one
of
these
phase
changes
releases
heat
while
the
other
requires
heat
to
be
added.
These
concepts
are
then
reinforced
in
a
demonstration
which
involves
heating
water
and

This
two-part
activity
provides
information
on
seasonal
changes
in
the
mass
balance
of
the
Antarctic
Ice
Sheet.
In
Part
1,
students
use
an
atlas
and
satellite
imagery
to
examine
the
geography
of
the
region
and
identify
seasonal
changes
in
the
boundaries
of
the
ice
sheet.
In
Part
2,
they
will
collect
a
series
of
images
of
the
Antarctic
ice
sheet
covering
a
period
of
several
years,
draw
the
boundaries
