In this activity students will discover that the density of water changes if its properties are altered by adjusting its temperature. They will also learn that when waters with different densities encounter each other, they behave in some interesting ways. This activity can stand alone or in combination with a salinity-related activity.

This
activity
will
help
students
understand
how
the
Northern
Lights
work,
what
causes
them,
and
how
to
observe
them.
They
will
use
charts
and
geometry
to
calculate
geographic
locations
of
aurora
based
on
satellite
data,
how
they
appear
at
different
latitudes,
and
their
height
above
the
ground.
Instructions
for
the
activity
are
provided,
and
an
extensive
list
of

to
additional

The
3-D
visualizations
of
molecules
and
minerals
at
this
site
utilize
a
plug-in
viewer,
which
allows
them
to
be
interactively
zoomed
and
rotated
so
they
can
be
viewed
from
all
angles,
much
as
with
a
real
molecule.
They
can
also
be
programmed
with
highlighting
features
that
allow
identification
of
specific
atoms,
structural
sub-components,
and
mineralogical
planes.
The

are

This
demonstration
aims
to
teach
students
about
the
nature
of
carbon,
the
different
types
of
compounds
it
exists
in
(e.g.
charcoal,
glucose,
carbon
dioxide),
the
biochemical
reactions
it
takes
part
in
(photosynthesis
and
respiration),
the
range
of
processes
that
carbon
and
carbon
compounds
are
involved
in
on
Earth,
and
how
these
link
together
to
form
the
carbon
cycle.
Students
will
be
reminded
that

affects
everyone's
daily
lives
and
learn
about
two
NASA

Earth
Science
missions,
CALIPSO
and

This article reports on how solder behaves in a weightless environment. The behavior of the solder on the International Space Station is described and shown in a video. This is important information for astronauts. If something breaks during a long trip to Mars, they will likely reach for a soldering iron to repair it. A diagram explains the behavior of the solder.

In
this
activity
students
pretend
to
be
part
of
a
research
team
working
to
find
out
more
about
volcanoes.
Their
assignment
is
to
gather
information
about
magma
and
present
it
as
part
of
a
television
program
to
educate
students
in
middle
schools.
The
goal
is
to
create
a
demonstration
that
will
show
how
the
composition
of
a
liquid
affects
its
viscosity.
Students
perform
two
demonstrations.

This
classroom
activity
has
students
determine
the
concentration
of
oxygen
in
air
at
their
location.
Oxygen
is
removed
from
a
trapped
volume
of
air
by
the
oxidation
of
steel
wool
and
by
measuring
the
volume
of
air
remaining
they
can
calculate
the
percentage
of
oxygen
in
the
air.
The
