In
this
activity,
students
examine
their
concepts
of
a
comet
by
designing
and
building
a
model.
The
goal
is
to
have
students
replicate
the
scientific
processes
of
observing,
modeling,
forming
an
explanation,
making
new
observations,
and
revising.
In
this
manner,
students
have
the
opportunity
to
emulate
the
experience
of
scientific
discovery
that
makes
science
so
exciting.
Younger
students
will

The
Global
Learning
and
Observations
to
Benefit
the
Environment
(GLOBE)
Database
houses
millions
of
student
observations
from
schools
worldwide.
The
purpose
of
these
activities
is
first,
to
help
guide
the
teacher
through
these
millions
of
data,
and
second,
to
inspire
teachers
and
students
to
both
collect
GLOBE
data
as
well
as
to
use
these
data
in
their
own
research.

This product illustrates how scientists learn about the composition of an asteroid by studying energy and neutrons that emanate from it. The Dawn spacecraft contains three instruments -- the Gamma Ray and Neutro Detector (GRaND), the Visible Infrared Spectrometer, and the Framing Camera -- that will provide answers to questions about the formation and evolution of the early solar system.

This
chapter
walks
users
through
a
technique
for
documenting
change
in
before-and-after
sets
of
satellite
images.
The
technique
can
be
used
for
any
set
of
time-series
images
that
are
spatially
registered
to
show
the
exact
same
area
at
the
same
scale.
In
the
chapter,
users
examine
three
Landsat
images
of
the
Pearl
River
delta
in
southeastern
China.

guide,
students
use
various
mathematical
skills
in
the
context
of
examining
an
ISS
EarthKAM
image
(ISS

of
farmland
in
Texas
and
New
Mexico.
They
randomly
select
a
sample
region
of
the
image,
count
the
number
of
fields
in
that
region,
and
estimate
how
many
fields
are
in
the
entire
image.
They
