Let me give you an example: Article: Homework can put you in a badmood , 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.

Article: Beach volleyball is one of those sports that can be an exciting game to play and watch, or, can just be about some friends getting together to have a great time. It's really easy, and all you need is sand, a net and a group of people, of any age or fitness level, who want to have fun. Beach volleyball can be played with as few as two people on each team, making a total of four people. However, if you are less skilled and experienced in the game, it will be easier to play with a larger team. The more players you have, the less ground each person will be responsible for covering and the more time they will have to recover in between shots. If you only have a few players, each of you will get quite a workout running for the ball after each volley. If you are looking for that relaxing, fun, low-key experience, choose larger teams. Beach volleyball is similar to regular volleyball in its rules. However, even experienced volleyball players do not realize how much more difficult it is to run and jump on sand. Since it is harder to move quickly on sand than a hard ground, play will be much slower than regular volleyball on a playground. When a player trains for beach volleyball, he will focus on building lower body strength as well as upper body. While he needs to be able to hit the ball with a great deal of power and accuracy , strengthening his legs is extremely important. Whether you are in it for the competition, or just to have a great time with your friends, beach volleyball can be very exciting and fun. You may even start out with friends and fall in love with the sport.
