On a Saturday night at home while relaxing with friends, a dog showed up at the house. In an attempt to find the legal owner and return the dog, we knocked on the door of the legal owner and an old man opened the door. This was the start of an interesting week.

    The old man sat down, made himself at home, and gifted us the dog. After a brief visit, he left, and we were now the proud owners of this dog. It takes experience and knowledge to know that our lifestyle can't satisfy the needs of this dog; the owner that gifted us the dog was mismatched for him as well.

    Three attempts to return the dog to his old owner failed. (I think he was avoiding us.) Because our lifestyle didn't allow us to give this poor dog the attention he needed, he disturbed the neighbors. They got involved. After we shared the story, they gained a new perspective and wisely stepped in to help us find a solution.

    One week later it was decided that dog would be picked up from us by the old neighbor. He would then return it to the previous owner who was more equipped to care for it.

    When faced with unexpected challenges in life, it helps to see everyone's perspective. We have to look at one another's perspective to solve a problem with honesty, experience and knowledge. That's the sign of a leader. Although the old neighbor typically has little to do with leadership, it did bring a neighborhood together to understand one another and work as a team to solve a problem.

    More than a decade ago, cognitive scientists John Bransfgord and Daniel Schwartz, both then at Vanderbilt University, found that knowledge was not the ability to retain facts or apply previous knowledge to a new situation but a quality they called "preparation for future learning." The researches asked fifth graders and college students to create a recovery plan to protect bald eagles from extinction. Shockingly, the two groups came up with plans of similar quality (though the college students had better spelling skills). From the standpoint of a traditional educator, this outcome indicated that schooling had failed to help students think about ecosystems and extinction, major scientific ideas.

    The researches decided to go deeper, however. They asked both groups to generate questions about important issues needed to create recovery plans. On this task, they found large differences. College students focused on critical issues. The college students had cultivated the ability to ask questions, the foundation of critical thinking. They had learned how to learn.

    Museums and other institutions of informal learning may be more suitable to teach this skill than elementary and secondly schools. At the Exploratorium in San Francisco, we recently studied how learning to ask good questions can affect the quality of people's scientific inquiry. We found that when we taught participants to ask "What if?" and "How can?" questions that nobody present would know the answer to and that would spark exploration, they engaged in better inquiry at the next exhibit—asking more questions, performing more experiments and making better interpretations of their results. Specially, their questions became more comprehensive at the new exhibit.

    This type of learning is not limited to museums of institutional settings. Informal learning environment tolerate failure better than schools. Perhaps many teachers have too little time to allow students to form and pursue their own questions and too much ground to cover in the curriculum. But people must acquire this skill somewhere. Our society depend on them being able to make critical decisions about their own medical treatment, says, or what we must do about global energy needs and demands. For that, we have a robust informal system that gives no grades, takes all comers, and is available even on holidays and weekends.

    Eleven leatherback turtles (棱皮龟) are swimming across the Pacific Ocean to the Galapagos Islands in a "race". It will be reported online to attract people's attention to the situation of the endangered (濒危的) animals.

    People have put small tracking devices (跟踪装备) on the turtles so that they can monitor their journeys as they head south from their birthplace to their feeding grounds near the Galapagos, about 1,500 km away.

    People can choose a turtle online and track it at http://www.greatturtlerace.com. The turtle that travels furthest in two weeks' swimming will be the winner.

    There is no prize for the winner of the "race". Rather, they just want to help people take notice of the dangers facing the animal that has lived in the oceans for 100 million years.

    Scientists say 95 percent of the turtles in the Pacific Ocean have disappeared in the last 20 years, because of human activities like fishing, stealing their eggs and building near their homes.

    Thousands of leatherback turtles lived at Playa Grande 10 years ago, but the number has dropped below 100 in the last 5 years.

    The leatherback turtle "race" will not be broadcast on TV at the same time because the turtles leave Costa Rica at different times. Instead, a group will provide a day-to-day showing of the first 14 days of their journeys at the same time as if they were racing.

    The activity will collect money to protect Playa Grande.

    Since the first Earth Day in 1970, Americans have gotten a lot “greener” toward the environment. “We didn't know at that time there even was an environment, let alone that there was a problem with it,” says Bruce Anderson, president of Earth Day USA.

    But what began as nothing important in public affairs has grown into a social movement .Business people, political leaders, university professors, and especially millions of grass-roots Americans are taking part in the movement. “The understanding has increased many, many times,” says Gaylord Nelson, the former governor from Wisconsin, who thought up the first. According to US government reports, emissions (排放)from cars and trucks have dropped from 10.3 million tons a year to 5.5 tons .The number of cities producing CO beyond the standard has been reduced from 40 to 9. Although serious problems still remain and need to be dealt with, the world is a safer and healthier place. A kind of “Green thinking” has become part of practices.

    Great improvement has been achieved. In 1988 there were only 600 recycling programs; today in 1995 there are about 6,600. Advanced lights, motors, and building designs have helped save a lot of energy and therefore prevented pollution.

    Twenty –five years ago, there were hardly any education programs for environment. Today, it's hard to find a public school, university, or law school that does not have such a kind of program. “Until we do that, nothing else will change!” say Bruce Anderson.

    We were silently waiting on the platform in the late afternoon. There he was, my 80-year-old grandfather with his silvery hair. And there I was, a teenage girl in my jeans and T-shirt. His aged but still clear blue eyes were taking in the scene as I wondered how I was going to get through the next two days. Why did I ever agree to accompany my cranky grandpa on a train ride from New York to Georgia?

    No one else wanted to be the fellow traveler since my grandfather refused to fly. In contrast, I loved to fly since I wanted to get to the destination as quickly as possible. No matter what anyone told my grandfather about the comfort and safety of flying, he refused to book a flight, saying, "It's not just the trip; it's the adventure of getting there."

    With my first step onto the train, the journey was already different from what I expected. The train was modem and filled with friendly travelers. We settled into the club car, where we could enjoy food and drinks while watching the scenery pass. Instead of listening to my music, I became a willing audience and learned family history that I had never had the time or patience to learn. With teary eyes, he told me that going to family events was hard for him since my grandmother died. It always made him think about those who were no longer with us. For the first time I felt I understood him. I gained a new appreciation for our time together.

    In this fast-paced world, we often miss important moments. There is great significance in listening to elders who offer a piece of their history and experience. I may be more open to opportunities to stay with my grandpa. Life isn't just about the destination; it's about the journey.

    Misael is three times the size of other children at his age due to a symdrome(综合症 状) which means he is unable to stop eating.

    He is so heavy that he often stops breathing while sleeping — leaving his parents fearing that one day he may not wake up. His dad Manoel Abreu, 38, said, "Everything is hard for him — he is a baby carrying an adult's weight. His heart must be working under a lot of pressure. If he doesn't get the treatment he requires, there is a very good chance that he will pass away."

    Miseal, from Sanot, Brazil, was born a healthy 6lb 6oz, but immediately he started piling on the pounds. Doctors believe he may be suffering from Prader-Willi symdrome, a rare genetic condition that leaves him with greed. He now weighs a heavy 178lb and is still gaining despite following a low-fat diet and walking for 40 minutes each day.

    Mum Josiane, 37, said, "He has been putting on a lot of weight since he was a baby—even when I was breastfeeding him. But it was only when he was one and a half years old that we began to worry. He was gaining 3kg a month and was starting to get very heavy. We know we could lose him at any time. Sometimes when he is sleeping, I watch him to see if he is breathing. I cry a lot because we want to help him. But I am also very proud of him because he doesn't surrender(投降)."

    Misael visits a doctor every three months to try to control his condition, but currently there is no cure for Prader-Willi symdrome. Paediatric neurologist(儿科神经科专家)

    Lucio said, "Every time we meet, he has put on a lot of weight — sometimes up to 5 kg. I think Misael could get help from someone outside Brazil — both medically and financially — so that he can get the laboratory and genetic testing he needs."
