A conservation cleanup project and an accidentalscholarship offer. That's coming up this Thursday on cnn student news. But ourfirst story involved the civil war in Syria. U.S. officials say they haveevidence that chemical weapons have been used in Syria. They don't know howthey were used, when they were used or which side used them. President Obamasays those details need to be sorted out.

The use of chemical weapons would be a gamechanger. That's not simply for the United States but for internationalcommunity we got to everything we can investigate and establish some certaintywhat exactly has happened in Syria, what is happening in Syria. When I ammaking decisions about America's national security and potential for takingadditional action in response to chemical weapons use. I've got make sure I gotfacts.

Chemical weapons can deploy any number ofway they can be introduced into food or water, they can be spread fromairplanes can even be launched as artillery shells. For example, this liquid poisonwould be blasted off, it would hit the ground as the liquid spread out it willturn into a gas that would simple affect everything in the region. That's theybelieve happen in several towns here in Syria. But here's insidious thing ifthey are really talking about sarin gas, it is colorless, it is odorless and ithas not test for people who are under attack would not even know it washappening to them. But they might have the symptoms because they could come onalmost immediately remember, this was developed as a pesticide and this is whatdoes to human to cause blurred vision, rapid breathing, heavy sweating,confusion, headaches nausea and at the very worst cases, convulsions, paralysisand death. What it is doing is attacking the nervous system. It's essentiallyshutting your body down. That is what kills people and why this is consideredsuch a bad thing. But there is a trick to all of these. The trick is even youhad a massive rocket barrage of sarin gas, you wouldn't necessarily know that’swhat happened, because even though it is lethal, it’s not long lasting, itdisperses very quickly. Well investigators now think, think they had someevidences that the Assad regime used sarin gas on people there, they would haveto work very hard to establish concrete proof.
