This
data
tip
from
Bridge,
the
Ocean
Sciences
Education
Teacher
Resource
Center
archive,
focuses
on
tides.
Students
learn
how
to
plan
for
tide-affected
activities
by
using
the
NOAA
Tide
Predictions
page
to
calculate
tidal
predictions
for
several
days
at
a
site
of
interest
in
the
coastal
United
States.
Students
are
also
linked
to
a
site
with
global
data
where
they
may
generate
a
graph

This
lesson
plan
presents
an
introduction
to
the
apparent
motion
of
the
Sun
across
the
sky
and
the
way
it
changes
in
summer
and
winter.
The
goals
of
the
lesson
are
to
recognize
the
daily
motion
of
the
Sun
across
the
sky,
defining
the
main
directions
of
east,
west,
south
and
north.
The
student
will
also
recognize
that
the
locations
of
sunrise
and
sunset
(for
viewers
north
of
the
equator)
migrate
southward

In
this
lesson
students
learn
to
recognize
the
types
of
tephra,
which
include
a
variety
of
ejected
volcanic
products,
and
that
the
distribution
and
type
of
tephra
can
be
used
to
locate
an
eruption
source
and
describe
the
style
of
an
eruption.
Students
also
learn
that
tephra
is
classified
by
size,
texture,
and
composition
and
as
a
result
of
this
lesson
will
be
able
to
identify
and
describe
the
origin

This
demonstration
uses
a
gyroscope
(a
bicycle
wheel
works
well),
string,
and
a
turntable
(optional)
to
show
how
the
equatorial
bulge
of
Earth
causes
precession.
By
balancing
the
spinning
bicycle
wheel
on
one
hand,
and
pulling
a
string
attached
to
the
top
axle
with
the
other,
the
axis
of
the
wheel
traces
out
a
circle
(precesses).
The
site
also
explains
how
the
moment
of
inertia
is
related
to
torque

This
lesson
on
the
cause
of
currents
and
water
circulation
in
the
Arctic
Ocean
will
require
students
to
investigate
the
influence
of
salinity
and
temperature
on
the
density
of
seawater
to
determine
what
factors
drive
water
circulation
in
the
Arctic
Ocean.
Students
identify
the
primary
driving
forces
for
ocean
currents
and
infer
the
type
of
water
circulation
to
be
expected
in
the
Arctic
Ocean,

In
this
activity
students
plot
the
latitude
and
longitude
involved
in
the
movement
of
the
Magnetic
North
Pole
over
a
period
of
time,
predict
its
location
by
the
year
2000,
and
justify
their
reasoning.
Students
will
discover
that
the
Magnetic
North
Pole
has
been
charted
over
the
past
several
hundred
years
and
that
the
pole
shifts
an
average
of
15
kilometers/

In
this
activity
students
use
web-based
archival
and
real-time
data
to
explore
how
auroras
change
with
time.
They
discover
that
during
the
1990's,
the
National
Aeronautics
and
Space
Administration
(NASA)
placed
research
satellites
in
orbit
around
the
Earth
to
keep
the
polar
regions
under
almost
constant
surveillance
for
signs
of
auroral
activity
and
that
this
data
helps
scientists
explore
the
connections

In
this
activity,
students
will
gain
an
understanding
of
how
geologists
determine
rates
of
sea
floor
spreading
between
two
tectonic
plates.
Using
a
strip
map
of
the
North
Atlantic
seafloor,
they
will
measure
distances
and
note
the
ages
of
the
strips
of
seafloor
basalt.
They
will
also
gain
experience
applying
some
basic,
useful
mathematical
concepts
such
as
the
calculation
and
use
of
velocities
and

This
unit
is
designed
to
acquaint
students
with
the
properties
of
magnetic
fields.
It
is
meant
to
introduce
the
idea
of
a
"field"
through
investigations
of
magnetic
fields
as
produced
by
various
common
magnetic
materials
and
direct
electrical
currents.
They
will
learn
that
the
difference
between
a
magnetic
field
and
a
gravitational
field
is
that
a
gravitational
field,
in
the
experience
of
a
student,

Students
use
wood
blocks
and
model
boats
to
investigate
how
the
shape
of
an
object
determines
the
friction
it
encounters
as
it
is
drawn
through
a
towing
tank.
They
learn
the
advantages
of
streamlining
and
increased
waterline
length
and
observe
that
the
shape
of
an
object
affects
its
stability.
Students
are
also
introduced
to
the
terms
power,
turbulence,
hydrodynamics,
work,
and
boat
design,
and
