This
interactive
lesson
on
metamorphic
rocks
starts
with
a
review
of
the
rock
cycle
and
goes
on
to
describe
the
relationship
between
metamorphic
rocks
and
their
parent
rock.
The
lesson
then
describes
the
agents
of
metamorphism
(temperature,
pressure,
and
chemical
change)
and
moves
into
a
discussion
on
contact,
regional,
and
dynamic
metamorphism.
The
remainder
of
the
lesson
consists

This
report
documents
the
findings
of
a
10th-grader
from
Utah
who
decided
to
test
water
samples
to
find
out
for
himself
how
safe
the
water
was
in
his
home
town.
The
narrative
essay,
with
illustrations
and
photographs,
discusses
how
his
biology
class
ignited
his
concern
for
environmental
issues.
It
describes
his
expedition
to
uncover
the
unseen
factors
affecting
the
water
quality
in
his
town,

This
activity
introduces
students
to
the
concept
of
the
chemical
formation
of
a
mineral
from
a
hot,
semi-liquid
melt,
and
to
basic
stoichiometric
concepts
regarding
the
formula
of
a
mineral
(or
chemical
compound).
It
can
be
performed
by
the
students
themselves
or
as
a
demonstration
by
the
teacher.
They
will
weigh
out
samples
of
iron
filings
and
of
sulfur,
test
them,

This
demonstration
reinforces
the
concept
that
minerals
can
form
even
at
low
temperatures,
meaning
that
these
processes
can
occur
at
or
near
Earth's
surface.
Using
'water
glass'
(sodium
silicate
nanahydrate)
and
any
of
a
variety
of
metal
salts,
the
teacher
can
grow
crystals
of
silicate
at
room
temperature
in
a
container
as
the
students
watch
and
record
their
observations.

Are we made of stars? This video segment features scientists studying light emissions from exploding stars called supernovas. It explains the process by which new elements are formed in these explosions and then disseminated to create planets and new stars. The segment is one minute fifty-five seconds in length. A background essay and list of discussion questions are also provided.

It's
remarkable
to
think
that
a
compound
renowned
for
its
safety
and
stability
in
commercial
products
could
have
dramatically
compromised
the
health
of
our
planet,
but
that's
just
what
chlorofluorocarbons
(CFCs)
has
done.
This
video
segment
describes
how
CFCs,
once
widely
used
in
refrigerators
and
aerosol
cans,
damaged
the
protective
layer
of
ozone
in
our
atmosphere.

This
project
is
designed
to
teach
high
school
students
about
air
pollution.
Students
research
types,
sources
and
effects
of
air
pollutants,
methods
of
controlling
air
pollution,
and
possible
solutions
to
problems
in
the
location
they
research.
Using
this
lesson
will
teach
students
to
gather
and
organize
data,
interpret
and
solve
problems,
make
decisions,
and
communicate
results
through
a
written
report
