This
activity
allows
students
to
experiment
with
different
soil
structures
and
discover
the
ability
of
each
to
carry
a
specific
load.
The
Tower
of
Pisa
is
leaning
because
it
was
built
on
highly
unstable
ground
right
above
an
old
river
bed.
Students
will
make
their
own
soil
mixture
and
see
how
well
it
supports
a
brick
on
end
to
learn
what
kind
of
soil
is
best
to
build
on.
This
activity
has

In
this
activity
students
will
focus
on
the
temperature,
density,
and
salinity
in
the
deep
sea.
They
will
be
able
to
explain
the
relationship
among
temperature,
salinity,
and
density;
and,
given
CTD
(conductivity,
temperature,
and
density)
data,
students
will
be
able
to
calculate
density
and
construct
density
profiles
of
a
water
column.
They
will
also
be
able
to
explain
the
concept
of
sigma-t,

Carbon is the basis of all organic molecules. It is also one of the most abundant elements in the universe. This video segment illustrates the special characteristics of carbon that make it an essential ingredient for life. The segment is one minute thirty-eight seconds in length. A background essay and list of discussion questions are also provided.

These
activities
are
aimed
at
simulating
metamorphic
rock
formation,
and
explain
how
increased
pressure
and
heat
affect
such
formation.
The
first
activity,
which
can
also
be
performed
as
a
teacher
demonstration,
simulates
the
idea
of
contact
metamorphism
by
investigating
the
effect
of
heat
from
a
beaker
of
hot
water
on
egg
white.
The
other
two
laboratory
activities
simulate
the

This site provides an interactive way to learn about the rocks and minerals found in everyday objects. Here, kids start with a clickable kitchen scene. For each item, students are taken to an information screen that explains a rock or mineral and how it has been used in the item. The list of over twenty items includes pots, pans, plates, flatware, acid, matches, and even the kitchen sink.

In
this
lesson,
students
will
investigate
the
technological
capabilities
that
are
required
for
the
operation
of
deep
sea
submersibles
and
understand
the
concept
of
buoyancy.
As
they
proceed,
they
will
research
the
development
and
use
of
research
vessels
or
vehicles
used
for
deep
ocean
exploration;
calculate
the
density
of
objects
by
determining
their
mass
and
volume;
and

Human
eyes
cannot
see
infrared
wavelengths,
but
with
the
help
of
false-color
imaging,
temperature
differences
become
visible
and
invisible
features
are
suddenly
illuminated.
This
interactive
gallery
shows
images
of
a
variety
of
objects
and
geothermal
features
in
both
visible
and
infrared
light,
and
explains
why
the
infrared
images
show
the
items
as
they
do.

In
this
activity,
students
grow
crystals
of
the
same
substance
over
different
periods
of
time
to
determine
the
relationship
between
time
of
growth
and
the
size
of
the
crystal.
Students
should
understand
that
in
this
investigation
evaporation
of
water
is
analogous
to
heat
loss
in
a
large
body
of
rock.
They
learn
that
small
crystals
grow
in
igneous
rocks
that
cool
relatively
quickly
while
larger
crystals

This
activity
will
allow
students
to
simulate
the
formation
of
sedimentary
rocks
by
compressing
sand,
water,
and
other
materials
in
a
syringe.
The
products
are
allowed
to
dry,
and
students
will
investigate
how
the
properties
of
the
samples
of
sedimentary
rocks
so
formed
are
dependent
on
the
extent
of
their
compaction
and
cementation.
The
activity
will
help
to
explain
that

This
demonstration
illustrates
the
properties
of
the
mantle
of
the
Earth,
using
potty
putty
mixed
with
a
solution
of
borax
and
simple
glue.
When
left
on
the
desk
the
potty
putty
will
sink
and
spread.
However
it
will
also
bounce
like
a
ball
if
enough
borax
is
used
and
it
can
be
stretched
far
more
than
plasticine
if
pulled
gently,
but
can
also
be
fractured
if
pulled
suddenly.
Students
will
