Example input: 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.

Q: Article: Star Wars Millennium Falcon This is a gift that, if we're being honest, many dads want to own for themselves. This huge ship is the greatest Star Wars toy. It lights up and makes some noises. Every boy from 3 to 53 will absolutely like it, if they can find room for it. I dare say even a few grandfathers might go for it. Biscuit--the Loving Pup You may clearly know that a pet can be a great thing to a child's development but you probably don't think that you can take care of a dog properly. The robot dog Biscuit is less likely to the disorder of your house and except for a few dead batteries, won't leave any surprises on the floor. It will be a good playmate for your kids. JVC KD-10 Headphones It's increasingly common for kids to enjoy themselves on long journeys with a portable DVD player or an iPod MP3, but the headphones that come with expensive electronics are seldom suitable for young ears. Kids should use JVC headphones that have a sound limiter that can be set by the concerned parent. Sparrow-kids Routemaster Kit Sparrow-kids Kit makes a huge range of craft tools.
