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

Water
quality
is
more
than
meets
the
eye.
Some
of
its
properties
are
invisible.
Teachers
using
this
module
will
focus
on
measurable
properties
of
water:
mass,
volume,
and
concentration;
temperature;
dissolved
oxygen;
pH;
and
nitrates;
and
their
effects
on
water
quality.
Each
of
these
properties
is
the
subject
of
a
lesson
plan.
The
lesson
plans
include
an
introduction,
lesson
objectives,
a
pre-test,

The
purpose
of
this
lesson
is
for
students
to
explore
the
nature
and
composition
of
a
comet.
The
student
will
select
ingredients
to
create
a
comet
and
will
learn
to
identify
ingredients
responsible
for
a
comet
nucleus,
and
how
changes
in
the
nucleus
when
the
comet
approaches
the
Sun
cause
two
different
kinds
of
tails
to
form.
Students
can
explore
some
facts,
myths,
and
legends
linked
to
the
appearance

This
site
is
all
about
snow
crystals
and
snowflakes.
The
many
facets
of
snow
crystals
are
described
here,
along
with
attempts
to
understand
their
formation.
This
site
includes
collections
of
super-high-resolution
snow
crystal
photos,
as
well
as
links
to
learn
about
snow
crystal
classifications
and
how
to
make
snow
crystal
fossils.
Included
in
the
study
of
how
snow
crystals
form,
these
researchers

This
set
of
resources
for
younger
students
includes
activities
and
information
on
thunderstorms,
tornadoes,
hurricanes,
blizzards
and
clouds:
how
they
form,
and
how
they
impact
our
lives.
There
are
games
about
clouds,
stories
about
extreme
weather
events,
and
a
set
of
activities
in
which
students
create
simulations
of
various
weather
phenomena
such
as

This
information
is
designed
to
belie
the
misconception
that
the
capacity
of
air
to
hold
water
vapor
is
temperature
dependent
and
that
air
can
become
saturated
with
water
vapor.
The
temperature
of
a
cloud
droplet
or
ice
crystal
will
be
nearly
the
same
as
that
of
the
air,
so
people
imagine
that
somehow
the
air
was
to
blame.
But,
if
the
other
gases
of
the
air
were
removed,
leaving
everything
else

This is a basic lesson on clouds. Very nice photos of cumulus and cumulonimbus clouds are presented on the page as well as a description of all major cloud types and their associated weather. Two activities are presented. One invites the learner to create a cloud, while the other involves creating a collage of cloud images along with information about the weather associated with each cloud type.

This information about the Lunar Prospector mission to the Moon discusses the possibility that ice exists on the lunar surface. The article indicates that no native water ice has been found on the moon. If ice has been found, it most likely originated from meteors and meteorites which periodically bombard the lunar surface.

The information on this site indicates that the life cycle of a glacier is more eventful than it appears. The site allows students to follow the journey of a single snowflake as it takes a ride through a glacier, a process that can take as much as 30,000 years to complete. It can be viewed as an interactive slide show or a single page of text and illustrations.

This
site
covers
many
of
the
components
of
cloud
formation
and
cloud
types.
Although
written
for
the
high
school
level,
the
middle
school
student
could
grasp
most
of
the
concepts
with
the
assistance
from
the
teacher.
Specific
concepts
covered
include
the
importance
of
and
mechanisms
that
produce
rising
air,
cloud
types,
and
ptyes
of
precipitation.
There
are
