The
purpose
of
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
effect
of
the
Earth.s
tilt
on
the
spread
of
sunlight
by
modeling
different
tilts
using
a
three-dimensional
polyhedron

The
purpose
of
this
resource
is
to
further
students'
understanding
of
the
causes
of
seasonal
change
using
visualizations
to
compare
the
effects
of
incoming
solar
energy
in
the
two
hemispheres.
The
class
reviews
global
visualizations
of
incoming
sunlight
and
surface
temperature
and
discusses
seasonal
change.
Students
use
the
visualizations
to
support
inquiry
on
the

This
Internet-based
collaborative
project
will
allow
students
to
share
information
about
water
usage
with
other
students
from
around
the
country
and
the
world.
Based
on
data
collected
by
their
household
members
and
their
classmates,
students
will
determine
the
average
amount
of
water
used
by
one
person
in
a
day.
They
will
compare
this
to
the
average

conduct
an
experiment
to
evaluate
the
effect

levels.
They
will
come
to
understand
the
effect
of
biodegradable
pollutants
on
water
quality,
design
and
conduct
an
experiment,
interpret
data,
suggest
additional
studies,

This
is
a
hands-on
activity
that
fosters
decision-making
skills
and
emphasizes
scientific
principles
such
as
objectivity
and
replication.
It
is
designed
to
show
that
pollutants
are
not
always
obvious
and
not
all
contaminants
pose
a
health
risk.
Students
will
learn
that
some
contaminants
can
be
detected
by
sight,
smell,
or
taste
and
that
others
are
not
detectable
except
with
sophisticated

Discussion
of
holes
in
the
stratospheric
ozone
layer
usually
revolves
around
investigations
of
the
thickness
of
the
layer
near
the
South
Pole.
This
online
activity
allows
users
to
study
the
thickness
of
the
ozone
layer
over
any
location
on
Earth
to
see
how
it
has
changed
over
time.
This
is
done
by

sea
ice
data
in

classroom.
The
data,
from

National
Snow
and
Ice
Data
Center
(NSIDC),
describe
sea
ice
concentration
and
extent
of
coverage.
Scientists
use
it
to
monitor
changes
in
the
concentration
and
coverage
of
ice
in
polar
regions
and
to
compare
changes
over
time,
such
as
