As we all know, children are our future, and it's up to us to arm them with the tools to succeed. Sadly, today's children are sometimes being armed with more dangerous tools like weapons, drugs and gangs in the USA. Once a relatively peaceful environment, many schoolyards of today are becoming unsafe for both students and teachers.

    Home schools are available to give you choices. Home schooling provides top-quality education, flexibility and freedom to create your own schedule. At Sunny Home School we believe the choice should be yours.

    Thanks to modern technology, home schooling information is becoming readily available across the nation. A recent study by the ITBS (Iowa Tests of Basic Skills) and TAP (Tests of Achievement and Proficiency) shows us that students of home schools do particularly well when compared with the nationwide average. In every subject at every grade level, students of home schooling scored obviously higher than those in public and private schools.

    If you're new to home schooling, you may be asking yourself, “Will home schools really work for my children?”

Fact: A nationwide study using a random selection of 1,516 families found students of home schooling to be scoring, on average, at or above the 80^th percentile (百分位的第80位) in all areas, on standardized achievement test. (Note: The national average on standardized achievement test is the 50^th percentile.)

    Collectively, the staff at Sunny Home School brings 65 years of experience in home schooling curriculum. We've placed students in the top 2% of the nation in math and many are successfully moving on to college.

    One study found that of the home schooled students, 94% said home education prepared them to be independent persons.

    Most people agree that honesty is a good thing. But does Mother Nature agree? Animals can't talk, but can they lie in other ways? Can they lie with their bodies and behavior? Animal experts may not call it lying, but they do agree that many animals, from birds to chimpanzees, behave dishonestly to fool other animals. Why? Dishonesty often helps them survive.

    Many kinds of birds are very successful at fooling other animals. For example, a bird called the plover sometimes pretends to be hurt in order to protect its young. When a predator（猎食动物）gets close to its nest, the plover leads the predator away from the nest. How? It pretends to have a broken wing. The predator follows the “hurt” adult, leaving the baby birds safe in the nest.

  Another kind of bird, the scrub jay, buries its food so it always has something to eat. Scrub jays are also thieves. They watch where others bury their food and steal it. But clever scrub jays seem to know when a thief is watching them. So they go back later, unbury the food, and bury it again somewhere else.

    Birds called cuckoos have found a way to have babies without doing much work. How? They don't make nests. Instead, they get into other birds' nests secretly. Then they lay their eggs and fly away. When the baby birds come out, their adoptive parents feed them.

    Chimpanzees, or chimps, can also be sneaky. After a fight, the losing chimp will give its hand to the other. When the winning chimp puts out its hand, too, the chimps are friendly again. But an animal expert once saw a losing chimp take the winner's hand and start fighting again.

    Chimps are sneaky in other ways, too. When chimps find food that they love, such as bananas, it is natural for them to cry out. Then other chimps come running. But some clever chimps learn to cry very softly when they find food. That way, other chimps don't hear them, and they don't need to share their food.

    As children, many of us learn the saying “You can't fool Mother Nature.” But maybe you can't trust her, either.

    A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.

     “It's extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components (元件),” said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own,” he said.

    They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it's connected to,” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.

    While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers' fields or on the battlefield. “Basically it should be able to take off, land and fly around,” he said.

    Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis.”

"Given that signs of Alzheimer's disease (老年痴呆症) start to accumulate in the brain several decades before the disease begins, understanding the connection between sleep and cognition (认知) earlier in life is critical for understanding the role of sleep problems as a risk factor for the disease," said study author Yue Leng, PhD, of the University of California, San Francisco.

The study involved 526 people with an average age of 40. They were followed for 11 years. Researchers looked at participants' sleep duration and quality. Participants wore a wrist activity monitor for three continuous days on two occasions approximately one year apart to calculate their averages. Participants slept for an average of six hours. Participants also reported bedtime and wake-up time in a sleep diary and completed a sleep quality survey with scores ranging from 0 to 21. A total of 239 people reported poor sleep with a score greater than five.

Researchers also looked at sleep fragmentation (碎片化), a measure of restlessness during the sleep period expressed as a percentage. The higher the value, the more sleep is interrupted. Participants were divided into three groups based on their sleep fragmentation score. Of the 175 people with the most interrupted sleep, 44 had poor cognitive performance 10 years later, compared to 10 of the 176 people with the least interrupted sleep.

After adjusting for age, sex, race, and education, people who had the most interrupted sleep had more than twice the possibility of having poor cognitive performance when compared to those with the least interrupted sleep. There was no difference in cognitive performance at midlife for those in the middle group compared to the group with the least interrupted sleep.

However, due to the small sample size, the researchers were unable to fully investigate potential race or sex differences. "More research is needed to assess the link between sleep disturbances and cognition at different life stages and to identify if critical life periods exist when sleep is more strongly associated with cognition," Leng said.

Discovering a hobby can lead to amazing results, as Maria Martinez, an 11-year-old with a heart of gold, has proven.

Just over a year ago, Maria came across the world of clothes-making, thanks to one of the Christmas gifts she received. Little did she know that this newfound ability would become a source of joy and purpose, not just for her, but also for countless furry friends.

"I got a gift permitChristmas to start clothes-making lessons," Maria said. "I really liked it."

After mastering the basics, an idea came to her mind during a visit to a local exhibition. Surrounded by pet owners and their pets, Maria had an idea that would change lives. Why not create lovely bandannas (头巾) for dogs and cats and use them to support animal shelters?

With great interest and the support of her grandmother, Maria turned a corner of their home into a busy working room. Together, they made many beautiful bandannas, each one filled with love and care.

But Maria's wish went far beyond creating decorations. She began donating her works to shelters like Claws Forever in Fall River, hoping to catch the eye of some people who can take these dogs and cats home.

Maria also began selling them through word-of-mouth and at various events. "At first she started just donating the bandannas because it took her much time to make them. Then she got more skilled and was able to buy cloth with some extra income that she was making from it," her mom, Crystal, said. "Maria is a really kind giving person and she doesn't want for much of anything. It makes her feel good to donate. We are proud of her." Ranging from $3 to $7, money from her sales is now donated to shelters, too. A few weeks ago, she donated more than $200 to the Kingston Animal Shelter.

"They were happy and really grateful, which made me feel really good inside," said Maria. "It makes me happy to see how it's impacted the people and dogs."
