Problem: Article: Homework can put you in a bad mood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.

Problem: Article: "Drink your milk. It's good for you!" You've probably heard that many times, and it's true. Milk contains calcium , which is necessary for keeping bones and teeth healthy and strong. The US government even requires milk as part of the National School Lunch Program, saying that students should drink one cup of fat-free or low-fat milk every meal. However, a group of doctors asked the government to take it away from the lunch program. The US 'Physician Committee for Responsible Medicine (PCRM) says, "Milk is high in sugar, fat and animal protein," all of which have negative effects on health. The PCRM says there are better and healthier ways to get calcium such as eating beans, broccoli, cereals and tofu. Orange juice and soymilk that have calcium added to them also supply the nutrient. "One of the only reasons people prefer milk is that it is going to help build strong bones," says Dr Neal Barnard, president of the PCRM. But milk may not be the best way to get calcium your body needs. Of course, calcium is important for healthy bones and teeth, but there are other things that affect your bone strength, such as genes, how much vitamin D you take in, and getting an hour's worth of exercise every day. Some people disagree with the idea that milk isn't important. Keri Gans, an American Dietitian, says "I don't think it's irresponsible to take this beverage that children enjoy it very much, especially among those who are unable to meet their nutrient needs for the day, and remove it from the lunch line." The U.S government is now considering the request of the PCRM, but a decision may be a long way off. Meanwhile, Marion Nestle, a professor puts it best: "Milk certainly has nutrients. Other food has the same nutrients. It's just food. As with other food, too much might be a problem."
