The
purpose
of
this
activity
is
to
demonstrate
how
individual
subjective
taste
is
a
factor
in
value
(in
terms
of
cost)
in
gemstones,
which
have
their
origin
in
the
natural
realm
of
minerals.
Students
will
discover
that
the
study
of
gems
is
an
exciting
and
intriguing
aspect
to
the
study
of
minerals
which
can
help
to
spur
interest
and
lead
to
deeper
understanding
of
mineral
and
crystal
formation.

This
slide
show
provides
basic
information
on
the
three
major
rock
types
and
the
rock
cycle.
Diagrams
of
the
rock
cycle
explain
the
processes
and
changes
that
connect
the
three
rock
types
and
illustrate
how
one
type
can
be
changed
into
another.
Each
of
the
three
types
(sedimentary,
igneous,
metamorphic)
are
described
and
illustrated
with
photographs.

This lesson uses a discrepant event to pique curiosity and provide an excellent metaphor for a problem in science that can be addressed in a scientific way. Water is poured into a magic box, and out comes a much larger volume of water (or other liquid). Students will learn that science is uncertain because scientists can make more than one workable model to explain their observations.

In
this
activity,
students
investigate
some
basic
principles
of
solubility
as
they
relate
to
underwater
volcanic
activity
and
hydrothermal
vent
systems.
They
should
be
able
to
describe
the
effect
of
temperature
and
pressure
on
solubility
of
gases
and
solid
materials,
describe
the
effect
of
temperature
and
pressure
on
the
phase
state
of
gases,
and
explain
observed
chemical
phenomena
around
deep-sea

Earth
has
been
significantly
altered
over
its
4.6
billion
year
history
by
climate
swings,
volcanism,
and
drifting
continents.
These
dynamic
conditions,
in
turn,
have
influenced
every
living
thing
that
has
inhabited
the
planet.
This
interactive
timeline
discusses
the
concept
of
deep
time,
and
allows
users
to
learn
about
geological
events,
evolutionary
transformations,
and
the

In
this
activity,
students
use
written
and
online
materials
to
answer
a
set
of
questions
on
the
general
properties
and
identification
of
minerals.
They
will
learn
about
physical
properties
such
as
color,
hardness,
and
cleavage;
special
properties
such
as
fluorescence
and
effervescence;
and
complete
a
chart
listing
properties
for
a
selection
of
minerals.
Links
to
the
necessary

of
the
world
wide
phenomenon
of
glacial
depletion
provides
several
examples
along
with
photographs
that
illustrate
the
disappearance
of
the

There
is
information
about
why
we
should
be
concerned,
including
the
loss
of
natural
reservoirs,
alpine
ecosystems,
and

of
past
climate
along
with
the

This
activity
gives
students
practice
and
a
chance
to
develop
expertise
in
using
the
test
for
hardness
in
identifying
common
minerals.
Following
a
discussion
and
an
introduction
to
Moh's
scale,
the
students
will
work
in
groups
to
test
minerals
whose
identities
are
known
against
their
standards
(common
substances
whose
hardnesses
are
known).
Once
the
known
minerals
have
been
tested,
the
students

In this activity, students will make a turbidity current. They will discover how fluids of differing densities interact with one another, learn some ways the densities of fluids can be changed and observe how density currents transport and deposit tremendous amounts of sediment in lakes and in the ocean. Additional options allow students to create and observe different kinds of density currents.
