1. David Appell. "Electromagnetic signals can predict earthquakes" New Scientist Print Edition 6/12/02.

2. I chose this article, "Electromagnetic signals can predict earthquakes", because it seemed intriguing and it was about the subject I was currently learning at school. This article is about electromagnetic signals that successfully predicted an earthquake in Japan. A new vocabulary word I learned from this article is propagated, which means to transmit or extend. Another word I discovered was proponents, which means one who argues in support of something; an advocate.

3. Content

a. The author was investigating whether or not the small group of Japanese seismologists was correct in their theory that they could truly predict an earthquake with electromagnetic signals.

b. The methods the author used to come to the conclusion was he interviewed the scientists in Japan that believed electromagnetic signals were the way to go and also their opponents who thought they were "grasping at straws".

The seismologists used telephone wires to measure low frequency electromagnetic waves for every 10 seconds.

c. The evidence that the scientists found to support their conclusion was that their geological field readings showed unusual changes and that the strength of the signal that they had been receiving continued to grow strong until the earthquake occurred.

d. The materials or instruments the author used to help them with this study was VAN method that can maintain electrical activity, telephone wires as antennas, Richter scale, and conductive channels.

4. This article called, Electromagnetic signals can predict earthquakes, is about how some seismologists in Japan believed they could predict earthquakes with Electromagnetic signals with some support of geological field readings and some stable proof that it works. Although there were many critics that believed they were grasping at their straws those two Greek seismologists in Japan really...

Denn eine neue Generation von hochgetunten und aerodynamisch optimierten Rennwagen sorgt im Rennzirkus für mächtig Unruhe. Vor allem einer der neuen Konkurrenten, der unschlagbare Jackson Storm, setzt Lightning gewaltig zu. Ob er in Zukunft noch ganz vorne mitmischen kann, ist fraglich. Aufgeben war für Lightning nie eine Option, aber steht nun möglicherweise doch sein letztes Rennen an?
