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,

Estuaries
have
physical
traits,
and
scientists
use
a
variety
of
measurements
such
as
water
depth,
salinity,
and
current
speed
to
describe
an
estuary.
This
site
describes
the
various
measurements
that
make
up
the
physical
properties
of
an
estuary,
using
Narragansett
Bay
as
an
example.
Specific
sections
of
this
site
focus
on
water
chemistry
(temperature,
salinity,
oxygen,
chlorophyll

Students
investigate
the
importance
of
water
historically
and
in
their
daily
lives
and
examine
the
nature
of
water
as
a
limited
resource.
Working
in
groups,
they
will
list
the
various
uses
of
water,
discuss
why
water
is
a
limited
resource,
research
technological
systems
that
are
intended
to
use
water
as
productively
as
possible,
and
create
"How
It
Works"
posters
for
presentation
to
the
class.

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
nice

This
is
a
multimedia
interactive
simulation
that
teaches
students
about
emergency
preparedness,
disaster
safety,
and
weather
and
storm
science.
In
the
simulation,
students
visit
a
Florida
family
and
end
up
preparing
for
and
riding
out
a
hurricane
which
hits
during
the
visit.
Students
can
track
the
storm
on
a
map,
watch
weather
updates,
prepare
emergency
supplies,
and
develop
a
disaster
emergency
plan.

In this lesson, students focus on the tremendous public interest in the potential of extraterrestrial life. Students read and discuss an article about the search for alien life. They then divide into small groups and discuss the issues and implications of this search. Finally, they write about the complex issues involved in this search and its implications in one of several suggested genres.

This
activity
describes
the
technique
of
preparing
"GIS-ready"
data
and
shows
how
to
map
that
data
and
conduct
basic
analyses
using
a
geographic
information
system
(GIS).
First,
you
will
download
and
format
near
real-time
and
historical
earthquake
data
from
the
USGS.
Using
latitude
and
longitude
fields,
you
will
then
plot
these
data
in
a
GIS.
Next,
you
will
analyze
patterns
by
querying
records
