Radio JOVE in Your School

In order to use Radio JOVE in the classroom, several issues need to be addressed:
  1. How does Radio JOVE fit into the science curriculum?
  2. What activities are involved in Radio JOVE?
  3. How does Radio JOVE align with the National Science Content standards?

1.  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".

2. What does participation in Radio JOVE involve?

Students can participate in Radio JOVE in three ways: 1. Purchase and build a Radio JOVE receiver and antenna kit and make radio observations of Jupiter Radio storms. 2. From the Radio JOVE website, use Radio JOVE Online to make observations using the radio telescopes at the University of Florida. 3. From the Radio JOVE website, use the archived data to listen to, record and analyze Jupiter radio data. Procedures for making observations are described in "Radio JOVE Activities".

3. Alignment of Radio JOVE classroom materials and activities with the National Science Content Standards:

The following National Science Content Standards are addressed by Radio JOVE - Content Standard A: Science as Inquiry: All students should develop: Abilities necessary to do scientific inquiry. Understandings about scientific inquiry. Content Standard B: Physical Science: All students should develop an understanding of: Structure of atoms. Structure and properties of matter. Motions and forces. Interaction of energy and matter. Content Standard D: Earth and Space Science: All students should develop an understanding of: Energy in the earth system. Geochemical cycles. Origin and evolution of the earth system. Content Standard E: Science and Technology: All students should develop: Understandings about science and technology. Content Standard G: History and Nature of Science: All students should develop an understanding of: Science as a human endeavor. Nature of scientific knowledge.
