If you build a campfire, you start with a large stack of sticks and logs. As the fire burns, the stack slowly shrinks. By the end of the evening, all that is left is a small pile of ashes. What happened to the matter that you started with? Was it destroyed by the flames? It may seem that way. What do you think happened? The truth is that the same amount of matter still exists. The wood changed not only to ashes, but also to carbon dioxide, water vapor, and other gases. The gases floated off into the air, leaving behind just the ashes. Although matter was changed, it was not created or destroyed. Because the same amount of matter still exists, we can say that matter is conserved. You may wonder how it can be conserved if something is now missing? Assume you had measured the mass of the wood before you burned it. Assume you had also trapped the gases released by the burning wood and measured their mass and the mass of the ashes. What would you find? The ashes and gases combined have the same mass as the wood you started with. This example illustrates the law of conservation of mass.

Question: "What can cause wood to change to ashes, carbon dioxide, water vapor, and other gases?"

Answer: "Cold"

Jenny was a 13 year old girl with blond hair and blue eyes. She had gotten out of her last day of school and was free for the summer. Two of her friends were going to the nearby beach to do some swimming and enjoy the sun. Jenny went with them and when they got there the beach was very full and there were people everywhere. They changed into their bathing suits and went to the water. The water was very cold. They chose not swim and walked to the sand. Then they laid down on some towels and enjoyed the sun. After several hours Jenny and her friends fell asleep. They woke up and the sun was beginning to set. When Jenny sat up she found that it was painful to touch her skin. When she looked down she saw that she had a very bad sunburn. Her friends were also very badly sunburned so they went home. Jenny's mother gave her a cream to put on the sunburn. Afterwards she felt a lot better and went to sleep.

Question: "Where did Jenny and her friends fall asleep?"

One of the most dramatic changes in priorities proposed by the City Council would shift $25.6 million from funding for court-appointed lawyers to the Legal Aid Society. In a document released yesterday to justify its reordered priorities, the Council contended that Legal Aid can achieve greater economies of scale than lawyers appointed pursuant to Article 18-B of the County Law. The Council document also noted that "inexplicably" 18-B lawyers are handling 50 percent of the indigent criminal cases in New York City, even though their mandate is to handle only multi-defendant cases where the Legal Aid Society had a conflict. In past years, the City Council had consistently added $5.6 million to the $54.7 million proposed for the Legal Aid Society by former Mayor Giuliani, bringing the total to just a shade over $60 million. But this year for the first time, the Council is proposing shifting more than $20 million in funds earmarked by the Mayor for 18-B lawyers to the Legal Aid Society, which would increase its total funding to $80.4 million. That would reflect a jump in its current finding of about one-third. Meantime, the City Council proposed slashing the Mayor's allocation of $62.8 million for 18-B lawyers by 66 percent, to $21.4 million.

While Nashiri was in Afghanistan, Nibras and Khamri saw their chance. They piloted the explosives-laden boat alongside the USS Cole, made friendly gestures to crew members, and detonated the bomb. Quso did not arrive at the apartment in time to film the attack. Back in Afghanistan, Bin Laden anticipated U.S. military retaliation. He ordered the evacuation of al Qaeda's Kandahar airport compound and fled- first to the desert area near Kabul, then to Khowst and Jalalabad, and eventually back to Kandahar. In Kandahar, he rotated between five to six residences, spending one night at each residence. In addition, he sent his senior advisor, Mohammed Atef, to a different part of Kandahar and his deputy, Ayman al Zawahiri, to Kabul so that all three could not be killed in one attack. There was no American strike. In February 2001, a source reported that an individual whom he identified as the big instructor (probably a reference to Bin Laden) complained frequently that the United States had not yet attacked. According to the source, Bin Laden wanted the United States to attack, and if it did not he would launch something bigger. The attack on the USS Cole galvanized al Qaeda's recruitment efforts. Following the attack, Bin Laden instructed the media committee, then headed by Khalid Sheikh Mohammed, to produce a propaganda video that included a reenactment of the attack along with images of the al Qaeda training camps and training methods; it also highlighted Muslim suffering in Palestine, Kashmir, Indonesia, and Chechnya. Al Qaeda's image was very important to Bin Laden, and the video was widely disseminated. Portions were aired on Al Jazeera, CNN, and other television outlets. It was also disseminated among many young men in Saudi Arabia and Yemen, and caused many extremists to travel to Afghanistan for training and jihad. Al Qaeda members considered the video an effective tool in their struggle for preeminence among other Islamist and jihadist movements.
