The
purpose
of
this
activity
is
to
measure
the
aerosol
optical
thickness
of
the
atmosphere
(how
much
of
the
sun's
light
is
scattered
or
absorbed
by
particles
suspended
in
the
air).
Students
point
a
GLOBE
sun
photometer
at
the
sun
and
record
the
largest
voltage
reading
they
obtain
on
a
digital
voltmeter
connected
to
the
photometer.
Students

The purpose of this activity is to introduce students to the concept of relative air mass and demonstrate how solar elevation angle affects the intensity of sunlight that reaches an observer on the ground. Students work in teams to calculate air mass using simple geometry. Teacher background materials are included.

this
resource
is
to
understand
what
causes
the
Earth's
seasons
with
a
focus
on
the
Earth's
tilt
and
spherical
shape.
Students
learn
how
sunlight
spreads
over
the
Earth
at
different
times
of
the
year,
emphasizing
the
solstices
and
the
equinoxes.
Students
investigate
the

The
Gulf
Stream
Voyage
is
an
online
multidisciplinary
project
which
utilizes
both
real
time
data
and
primary
source
materials
to
help
guide
students
to
discover
the
science
and
history
of
the
Gulf
Stream.
Students
will
investigate
this
great
ocean
current,
how
it
affects
the
Atlantic
Ocean
and
some
of
mankind's
experiences
dealing
with
it.
This

This
article
deals
with
the
phenomena
of
El
Nino
and
La
Nina.
Topics
include
the
apparently
widespread
effect
of
these
phenomena
on
weather
systems
around
the
Earth
and
new
methods
to
detect
their
arrival
and
departure.
There
is
a
discussion
of
the
use
of
SeaWIFS
satellite
data
to
detect
changes
in
the
distribution
of
oceanic
algae
(phytoplankton)

The
purpose
of
this
activity
is
to
measure
ozone
concentrations
at
ground
level.
Students
deploy
a
strip
of
paper
that
changes
color
in
the
presence
of
ozone.
They
use
an
ozone
reader
to
determine
the
amount
of
ozone
in
ppb
as
indicated
by
the
color
change
of
the
paper
strip.
Intended
outcomes
are
that
students
will
learn
to
measure
the
concentrations
of
ground-level
ozone
in
the
atmosphere
and
to

have
students
use
GLOBE
data
and
graphing
tools
to
compare
the
influence
of
latitude,
elevation,
and
geography
on
seasonal
patterns.
Students
analyze
the
graph
of
the
past

at
their
site.
They
compare
this
graph
to
