Integrating
Radio JOVE
into the
science
curriculum:
In
general,
the
concepts
involved
with Radio
JOVE
involve
the
interaction
of moving
charges
with
magnetic
fields.
The
appropriate
position
within the
course
outline
and the
level that
the
material
should be
presented
at are
best
determined
by the
teacher.
What is
provided
here are
some
general
descriptions
of the
topics and
some
suggestions
about
their
integration
into the
science
curriculum
at the
ninth
grade
(Physical
Science
and Earth
Science)
and
twelfth
grade
(Physics)
levels.
Physical
Science
topics:
Waves
- Waves
are
disturbances
that move
through
space.
Charged
particles
(ions) -
Increasing
the energy
of an atom
can result
in the
removal of
an
electron
and create
an
ion/electron
pair.
Magnetic
fields -
The region
around a
magnet
where the
magnetic
effect is
felt is
the
magnetic
field.
Electromagnetic
spectrum -
Moving
charges
result in
the
creation
of
electromagnetic
waves of
various
wavelength
and
frequencies
all
traveling
at the
speed of
light.
Radio
waves
- Charges
moving in
large-scale
motions
generate
long wave
electromagnetic
waves,
i.e. radio
waves.
Motors
and
generators
- Movement
of
electric
charge in
a magnetic
field can
cause
forces to
be exerted
on the
moving
charge.
Earth
Science
topics:
Earth's
magnetic
field
- Earth's
magnetic
field is
shaped
like that
of a bar
magnet.
Planetary
magnetic
fields
(Jupiter) -
planets
with
active
cores have
magnetic
fields.
Jupiter
has a
strong
magnetic
field.
Jupiter's
moons (Io)
- Io is
the only
body in
the solar
system,
other than
Earth,
known to
be
volcanically
active at
this
time.
Radio
astronomy -
Some
objects in
space emit
radio
waves
because of
charges
making
large-scale
movements
in the
magnetic
field of
the
planet.
Physics
topics:
(Physics
topics on
this list
assume
that the
student
has been
exposed to
the
Physical
and Earth
Science
topics
listed
above at
an
introductory
level.)
The
generation
of Earth's
magnetic
field -
Movement
of charged
particles
in the
liquid
outer core
of Earth
produces
Earth's
magnetic
field (the
dynamo
theory).
Atomic
energy
levels and
ionization.
-
Providing
energy to
an atom
will raise
the
electrons
to higher
energy
levels.
Providing
enough
energy
will
remove an
electron
from the
atom,
creating
an
electron/ion
pair.
Ultraviolet
light is a
form of
energy.
-
Ultraviolet
light can
ionize
some atoms
(sulfur
for
example).
Movement
of charged
particles
in a
magnetic
field -
Movement
of a
charged
particle
at right
angles to
a magnetic
field will
cause the
particle
to travel
in a
circle (F
= qvB).
Charges
moving in
a magnetic
field are
accelerating
- Circular
motion is
accelerated
motion.
Charges
encountering
a magnetic
field at
other than
a right
angle
spiral
along the
magnetic
field
line. -
The
component
of the
velocity
perpendicular
to the
field
causes
circular
motion;
the
component
of
velocity
parallel
to the
field
carries
the charge
along the
field line
(inertia).
Accelerating
charges
radiate
energy
- The
frequency
is the
frequency
of
rotation
of the
circular
motion.
Radio
waves are
long wave
electromagnetic
waves. -
Charges
accelerating
in a
planetary
magnetic
field
radiate
radio
waves.
Support
materials
for use in
integrating
Radio JOVE
into the
science
curriculum
are
included
in "Classroom
Exercises".

can buy
