To students who have heard it all before, Bill Nye the Science Guy brings an effective way to make sure they pay attention. He breaks up the science instruction with an energetic blend of silliness and outright comedy, and kids can't help but absorb an appreciable amount of information. In this episode of his popular series, Nye points out that the Earth is a gigantic magnet while explaining the planet's magnetic field. He talks about the basic attract/repel attributes of magnets, the phenomena of the aurora borealis, and the magnetite in the brains of migratory birds.
