MPAA Rating: PG-13 for for sci-fi life/death situations and brief strong language. Film Information From IMDb.com: The Core
What would happen if the earth’s core stopped rotating? This question forms the premise for the movie, The Core. The earth’s magnetic field could apparently collapse. The resulting chaos could include colossal lightning storms, massive earthquakes, computers going crazy, and animals losing their ability to navigate. Apparently, this may have happened on the Earth every 200,000 years or so. It’s been over 700,000 years, however, since the last time it happened, which makes us very overdue for the next shift. The scientific advisor on the film was J. Marvin Hernadon, a notable geophysicist.
Project One: Watch The Core. Write a paper outlining which events occuring in the film appear scientifically plausible and which ones appear implausible. Research the possibilities using the Internet links below. Support your arguments. Project Two: Research the phenomena related to the changing polarity of the earth’s magnetism. Make a chart of all of the catastrophic changes that could take place the next time the polarity changes. Project Three: Draw a cutaway diagram of what the earth looks like from its surface to the inner core. Be sure to label each of the parts and color each one. Design a key that shows the various geologic layers and structures.
The Core View the trailer for the film, find out about the crew in the movie or the one that created the film, watch video clips and interviews, and investigate the effect something like this would have on mother nature.

Conversation for Exploration You can listen to audio clips, as well as read this interview with J. Marvin Herndon.

This is the final section of 3-part series, which deals with the earth’s core and the magnetic poles. Don't stop there, however, because the first two parts are equally fascinating.

How will this effect the Earth? Find out the answer and more. Source: The Antarctic Connection
