Have you are burned something on the stove or in the oven? Do you know why things burn? It all has to do with temperature. Changes in matter are affected by temperature. For example, what if you place a cake in the oven and you leave it in too long? What do you think will happen? Thats right, it will probably burn. The same thing will happen if the oven setting is too high and you apply too much heat. In either case, heat has affected the rate of change in matter. Its probably obvious that when the temperature is increased a chemical change, like cooking, will occur faster. What about a physical change? Are physical changes affected by temperature? Most of us have seen steam rising off a wet road after a summer rainstorm. This happens because the road surface is very warm. The warm road and warm air temperature causes the water to evaporate quickly. The liquid water is turning into water vapor, but it is still water. The evaporation of water is a physical change. So yes, temperature affects the rate that physical change occurs.

Question: "What is causing cakes in the oven to burn and water from the road to evaporate on the hot day?"

Response: "Rise in temperature"

Federal health authorities Monday added 58 types of cancer to the list of covered illnesses for people who were exposed to toxins at the site of the World Trade Center in the aftermath of the September 11 attacks. The addition finalizes a recommendation from Dr. John Howard, administrator of the World Trade Center Health Program. Howard proposed in June that the program accept the recommendations of its Science/Technical Advisory Committee and add some cancers to the coverage list -- 14 categories in all. Firefighters responding to 9/11 at increased cancer risk The advisory committee review called for expanded "coverage for certain types of cancer resulting from exposure to toxins released at Ground Zero." "The publication of this final rule marks an important step in the effort to provide needed treatment and care to 9/11 responders and survivors through the WTC Health Program," Howard said in a statement Monday. The rule is expected to be published Wednesday in the Federal Register, and will take effect 30 days after its publication, Howard said. 9/11 detective dies after battle with lung cancer First responders, volunteers, survivors of the attacks and residents near the site who meet specific qualifications will be eligible for coverage, according to the World Trade Center Health Program. According to the proposed rule, an estimated 950 to 2,150 people would take advantage of the additional coverage. The estimated cost for the total cancer treatment ranges between $14.5 million and $33 million, the proposal said.

Jack and Mackenzie wanted to do something fun during their day off from school. They knew that the library had story time on Monday, Tuesday, and Wednesday. Their mother told them they could go to the library every Tuesday for their story time. They packed up the car and drove to the library, ready for a fun morning. When they arrived to the story room, there were lots of other children their age, all sitting cross-legged and ready for the story of the day. The teacher told them they would be reading "The Wild Horse". She began to tell the story of Majestic, the wild horse who could not be calmed. His people had tried and tried to break him, but he was wild at heart. Every time they took him to the river to drink, he would run straight into the water and get soaking wet! He would splash and play until he was ready to go back home, where he would sleep for hours, having worn himself out playing.

Question: "Majestic was the main character of which story?"

Response: "Majestic the Horse"
