In
this
lesson,
students
will
view
salt
under
varied
magnifications
and
begin
to
construct
the
understanding
that
materials
may
be
composed
of
parts
that
are
too
small
to
be
seen
without
magnification.
They
will
observe
salt
with
the
naked
eye,
and
then
under
a
hand
lens,
microscope,
and
the
electron
microscope
(the
electron
image
is
via
the
Internet).
In
order
to
complete
this
lesson,
it
is

a
detailed
explanation
of
the
chemistry
and
properties
of
water.
Animated
diagrams

of
the
water
molecule,
how
water
molecules
link
together,
what
the

structure
of
ice
looks
like,
and
how
acids
and
bases
are
formed.
There
is
also

The
colligative
properties
of
solutions
consist
of
freezing
point
depression,
boiling
point
elevation,
vapor
pressure
lowering,
and
osmotic
pressure.
These
properties
ideally
depend
on
changes
in
the
entropy
of
the
solution
on
dissolving
the
solute,
which
is
determined
by
the
number
of
the
solute
molecules
or

does
not
depend
on
their
structure.

This presentation, hosted by NASA describes Messenger's mission to determine water-ice concentration at the poles of Mercury using the technique known as planetary neutron spectroscopy. It has been estimated that there may be up to 1 trillion metric tons of water ice on Mercury. Scientific illustrations accompany the video lecture.
