No one ever said science education was easy. Certainly the concepts we teach, like conservation of momentum (动量守恒) or quantum mechanics (量子力学)，can be hard to grasp. But what really makes our reaching complicated is that we're also trying to teach a deeper lesson at the same time — to help students understand the nature of science itself.
All too often, young people get the impression that science is about learning certain "laws" and then applying them to different situations. After all, that's what we make them do on tests, to show that they've been doing the work. But that's not it at all. Science is the process of building these concepts through the collection of experimental evidence.
And while I'm on it let's call these concepts what they really are — not laws, but models. Science is all about building and testing models. It's difficult to help students understand that aspect of science when we just give them the models to begin with. Sure, in physics we often include historical or mathematical evidence to support big ideas, but that often isn't enough.
Of course, we can't start from scratch. If students had to build their own models from the ground up, it would be like trying to learn programming by inventing computers. As Isaac Newton is supposed to have said, we stand on the shoulders of giants. We must take models built by others and go from there.
What I'd like to suggest is that this actually provides a great way into the adventure of science and an opportunity to meet our objectives as educators. If you can create a situation that challenges students' assumptions and produces conceptual conflict, that's a great opportunity for learning.

A study of 192 third and fourth graders, generally aged eight and nine, found that children who cut the number of hours spent watching television gained nearly two pounds(0.9kg) less over a one-year period than those who did not change their television diet.
"The findings are important because they show that weight loss can only be the result of a reduction in television viewing and not any other activity," said Thomas Robinson, a pediatrician(儿科专家) at Stanford University.
"American children spend an average of more than four hours per day watching television and videos or playing video games, and rates of childhood being very fat have doubled over the past 20 years," Robinson said.
In the study, presented this week to the Pediatric Academic Societies‘ annual meeting in San Francisco, the researchers persuaded about 100 of the students to reduce their television viewing by one-quarter to one-third.
Children watching fewer hours of television showed a significantly smaller increase in waist size and had less body fat than other students who continued their normal television viewing, even though neither group ate a special diet or took part in any extra exercise.
"One explanation for the weight loss could be the children unstuck to the television may simply have been moving around more and burning off calories," Robinson said.
"Another reason might be due to eating fewer meals in front of the television. Some studies have suggested that eating in front of the TV encourages people to eat more," Robinson said.

【推荐2】4 Highly Outstanding Awards in Architecture
Pritzker Architecture Prize
Founded in 1979 by the Pritzker family, and funded by their Hyatt Foundation, the Pritzker Architecture Prize aims to honor a living architect or architects whose built work demonstrates a combination of those qualities of talent, vision and commitment, which has produced consistent and significant contributions to humanity and the built environment through the art of architecture. The annual award includes a grant of US $100, 000.
Architecture Master Prize
Established in 2016, the Architecture MasterPrize (AMP) was created to honor, celebrate and share the very best projects in the fields of architectural design, interior design, and landscape architecture. Unlike other awards, the AMP is open to submissions from all architects, across the world, whether students just beginning their journey into the discipline or those who have established experts in their field. Split into two categories—professional and student winners—the AMP has very quickly established itself as the home for innovative thinking, promoting new ideas.
RIBA Awards
Founded in 1834, the Royal Institute of British Architects (RIBA) organizes a number of awards as a part of their program. The latest winner of the RIBA International Prize, Children Village, by Aleph Zero and Rosenbaum of Brazil, demonstrates exactly what the RIBA jury is looking for—a project which fits its environment perfectly, achieving precisely what was needed in the brief but going beyond this, into those rare levels of perfection.
AIA Gold Medal
The American Institute of Architects (AIA), founded in 1857, runs more than thirty award programs, with the Gold Medal being the most famous and prestigious.

【推荐3】A new study found evidence that dogs developed in physical ways to present “puppy dog eyes” as a way to help connect with humans.
The study compared the facial muscles of dogs and wolves, which share ancestral history. Dogs broke off from wolves after being domesticated about 33,000 years ago. During that time dogs changed physically and behaviorally to adapt to life with humans.
The researchers examined the heads of six dogs and two wolves for comparison. They found the facial structures of both animals were mostly very similar. But one major difference was found above the eyes. The dogs were found to have two well-formed muscles around the eye that were not present in the wolves. These small muscles permit dogs to raise their inner eyebrows, the study found.
Juliane Kaminski, a comparative psychologist from the research suggests this eyebrow-rising movement causes “a warm” feelings in humans because it makes the dogs’ eyes appear larger. This expression also makes the dog look more like a human baby. The eye movement is similar to that which humans make when they are sad.
“The evidence is very obvious that dogs developed a muscle to raise the inner eyebrows after they were domesticated from wolves,” Kaminski said.
In a separate part of the study, the researchers observed how 27 dogs and nine wolves interacted with a human. “We also studied dogs’ and wolves’ behavior. And when exposed to a human for two minutes, dogs raised their inner eyebrows more and higher than wolves,” Kaminski said.
The researchers suggest that the eye movements developed over time as a way for dogs to get humans to do things for them, such as giving them food, care or attention.The only dog species in the study that did not have the muscles was the Siberian husky, which is an ancient kind of dog. The husky could be the best living example of what the link between dogs, and wolves looked like.

【推荐1】So far this winter, a theater in the Alps has staged more than 60 unique concerts. Winter temperatures in the remote mountain village can drop high below zero. Performers wear down jackets and play ice instruments. In fact, almost everything from drums and guitars to horns and harps at the music festival is carved from ice even the stage the musicians play on. The audience sits on ice chairs and benches and claps their hands to listen, both to praise the performers and to keep themselves warm when the air flows through.
The musical instruments used were almost entirely made by an American ice artist, Tim Linhart. Since he created his first musical instrument out of ice more than a decade ago, he has already carved various ice instruments, including violins, violas, timber drum sets, xylophone, double bass, mandolin and cello. He also created his own large wind instrument, which uses the vibration of an ice tube to produce sound when the air flows through.
Linhart makes the different parts of the ice instrument and then uses a liquid mixed with snow to glue them together, with a metal support placed where the strings need to be. A violin can usually be made in two or three weeks, while larger instruments can take more time and efforts, sometimes taking months to make.
An ice instrument has a clearer sound than a wooden instrument. However, ice instruments are more easily broken or damaged than ordinary instruments. The temperature in the ice theater changes depending on the number of people in the audience. This also changes the temperature of the ice instruments, which in turn affects the 1 sound they produce. Musicians need to tune their instruments frequently during performances.
Although playing an ice instrument is not easy, Linhart believes that ice and snow are good materials for making instruments. The only downside is melting when the temperature is above freezing.

【推荐2】Scientists in the U.S. have created an artificial sunflower less than 0. 04 inches wide that can bend towards a light source and harvest solar energy. The flowers were found to be about 400 percent more efficient than other equipment, making them promising technology for solar power potentially even as a power source for solar-based spaceships.
The team, led by researchers from the University of California, Los Angeles, was looking to improve. the efficiency of solar cells by modeling after a feature of nature-phototropism. This is where a plant adjusts itself to face the sun, getting the most amount of energy it can get. In a study published in Nature Nanotechnology, the team said it was a ''big challenge''.
However, this problem has now been overcome. The team has developed a polymer(聚合物) that is responsive to being simulated by light, The system, which they have named SunBOT for short, is able to instantly explore and track a light source. It can do this across a range of temperatures without power supply or any human intervention.
The researchers used the polymer to create a ''stem''. Then they placed a material commonly used in solar cells on its top, representing the ''flower''. When the team shone a light at the SunBOTs, the polymer began heating up and shrinking, causing the stem to bend so the flower faced the light.
The researchers tested their artificial sunflowers to see how efficient they were at harvesting solar energy Findings showed they were up to 400 percent more effective than non-phototrophic materials.
The practical applications of SunBOTs are some way off. The study shows a proof of concept, but the technology will need to be scaled up to be used commercially. However, the team is confident it could one day be used a across a broad range of industries.
This work may be useful for solar harvesters signal revere smart windows, self-contained robotics solar sails for spaceships and intelligent energy generation (for example, solar cells and biofuels), the scientific team said.

【推荐3】Noise created by humans, such as car traffic, quieted by about 30% between late March and early May, 2020, when Governor Greg Abbott closed schools and restaurants across Texas, according to analysis by researchers at Southern Methodist University (SMU).
“There was quite a big change in some areas,” said Stephen Arrowsmith, a seismologist at SMU, who took on the project with a class of undergraduate and graduate students. Arrowsmith and his students looked at data from a dozen seismometers (地震仪) across North Texas. Seismometers are used to detect earthquakes, but they are sensitive to just about everything that makes the ground vibrate, such as strong winds, ocean waves, construction and traffic.
The idea of using seismometers to track urban noise gained popularity last March when Belgian seismologist Thomas Lecocq posted some of his urban noise data from Brussels on Twitter. Lecocq, of the Royal Observatory of Belgium, received such an enthusiastic response from scientists that he launched the group “Lockdown Seismology” online. “It’s where bored seismologists around the world are working together,” Arrowsmith joked.
Arrowsmith hopes his findings will contribute to a growing list of creative ways in which researchers are using seismometers. In his course, Arrowsmith teaches students how seismic stations can help investigators solve crimes, like terrorist bombings, aid scientists in tracking nuclear tests or assist inspectors in investigating accidents, like chemical plant explosions. One potential application of his research is to better understand the shallow layers of Earth beneath cities. “That could be useful in places where there’s a real seismic hazard (风险), like San Francisco or Los Angeles,” he said, “where just knowing what that shallow structure is tells you a lot about how it would respond in a big earthquake.”

【推荐1】Faced with greater competition, movie theaters have tried multiple experiments to upgrade the cinematic experience, including bigger and brighter screens and rumbling(折叠) seats. But a major challenge for exhibitors is to make the experience more attractive without depending on tricks.
One local theater, Regal L. A. Live, is experimenting with an idea that managers say strikes the right balance between so-called increase and sensory overload. The downtown L. A. theater plans to introduce Immersive Cinema Experience known as ICE technology in one of its auditoriums(礼堂) this fall.
The 190-seat auditorium will feature a traditional screen at the front, like any other theater. But the audience will also have five LED screens on both sides that will flood moviegoers' peripheral (周围的 ) vision with lights and colors based on what's playing on the main screen. For example, if you're watching a scene that takes place in the African desert, the LED might shower the audience with enveloping colors of sky-blue, sun-like yellow sand. But importantly, viewers won't have to turn their necks to catch any additional onscreen action. "When you' re watching the movie, you actually feel very absorbed into the film," said Shelby Russell, a manager at L. A. Live. "It strengthens the mood of each of the scenes."
Regal L. A. Live will be the first U. S. theater to employ the technology. Managers did not say how much tickets will cost, but like other previous formats such as Imax, they will be more expensive than standard admissions.
Other cinemas have tried to introduce some other formats as theaters face growing threats from popular media. Results have been mixed, though. 4DX, which uses seat movements, water and scent effects, operates in more than 620 theaters around the world. On the other hand, Barcoo Escape, a once promising idea for a three-screen theatrical design, failed to catch on. Shelby said the success of ICE theaters in France, where it competes with Imax, indicates well for its U. S. expansion. "The problem with other formats is that they distract the moviegoer from the film," Shelby said. "ICE appeals to a very large audience."

【推荐3】Jac Grimes plays Santa in Greensboro, North Carolina. He gave up home visits which make up about a third of his business. He did it not just for his own health, but to prevent passing the virus from one family to the next. At a farmer's market where he works every year, Grimes dresses up as Santa and sits in a parking area. He talks to children who remain inside their cars.
The virus has many Santas and parents turning to online visits. Those visits have led many Santas to turn to their children and others for help in learning new computer skills. "It has been a challenge （挑战），" said Christopher Saunders, a Santa performer in Tool, a small town near Dallas, Texas. But Saunders and others say that instead of in-person visits, online visits are good, if imperfect.
Even Santas with the best jobs are hurt. Howard Graham has played Santa for eight years at New York's Radio City Music Hall. The place is known for its famous Christmas show with the Rockettes, a dance group. This year, he is making online visits and working five days with a historic railroad in Pennsylvania. “I love what I do... bringing them （children） a little bit of smile and hope," said Graham.
Brad Six first played Santa 35 years ago. He recently sat on Santa's chair for three hours at a shop in Miami. As families sat in front of a glass barrier（屏障）for photos, Six turned his head so that his face protection did not reflect （反射）the camera's light. He happily waved at children around the barrier so they could tell him their wish lists-from a distance about 1.8 meters away.
Six said the situation was a little easier physically on Santa's back because he didn't have to pick anybody up, but it was not as enjoyable because Santa didn't get the interaction （互动）he normally gets. This was definitely different, but the kids were excited and that was what mattered.

【推荐1】If you’ve ever been annoyed by the sound of someone eating, especially as they noisily slurp(出声地吃) noodles, don’t worry, you’re not alone.
A company has recently designed a fork that connects to an app on your smart phone, which will then play noise cancelling sounds if you happen to slurp your noodles too loudly.
The fork was designed with a microphone in its handle that is trained to recognize the sound of slurping. The microphone will then send a signal to the phone app, setting off the noise cancelling sounds.
The company that designed the fork, called Otohiko fork, was inspired by what is called “ noodle harassment” by social media users, which is running wild in Japan.
“The Japanese, who generally dislike noisy eating, consider it proper and even preferable to suck up one’s noodles with a loud slurping sound.”
Unfortunately for visitors, however, such enthusiastic slurping tends to grate on their nerves, which is what lead to the creation of the phrase “noodle harassment” in the first place.
The company behind the fork, Nissin, is the very same company that invented Cup Noodles, who brought instant noodles to the world nearly 70 years ago, so they are definitely worried about whether or not foreigners are put off by the sound of slurping noodles.
The fork is being sold for a good $ 130, but those bothered enough by noodles slurpers will likely find it well worth the money.
Nissin is only planning a limited run of 5,000 forks for the time being, which can now be pre-ordered only through their website.
The company is planning to begin releasing them just in time for the holidays. Of course, it still remains to be seen if the fork can be programmed to drown out the sound of loud chewers, which is probably of greater concern to sensitive western friends.
1. From the passage we can know that _______.| A．a microphone in the Otohiko fork’s handle is designed to cancel the slurping sound. |

【推荐2】Switching on the lights at night is second nature to most people in the developed world. But electricity isn’t a given in many other parts of the globe.
“A billion people on our planet still lack reliable access to electricity. For them, one of the central applications of electricity is lighting,” says Aaswath Raman, U.C.L.A. materials scientist.
Solar cells can provide remote areas with electricity during the day but require batteries to store that energy for use at night. Raman steam has developed a potential solution: a simple thermoelectric device that produces power when it s exposed to the cold night sky.
All objects, Raman explains, radiate heat. “So a surface that’s looking up at the night sky will, all by itself, send out more heat than the sky sends back to it. It escapes to the upper atmosphere and even out to outer space. And it’s something that anyone can observe at night. So if you go and measure the roof temperature on your house in the early morning hours, say, you should read a temperature that is much lower than the immediate surrounding air temperature.”
Raman reasoned that this temperature difference could be employed to produce electricity. His team built their device using an aluminum disk that acts as a radiative cooler. Its cool side faces the night sky, while its other side is warmed by the air around it. As heat escapes upwards, a thermoelectric generator transforms the temperature difference into electricity that powers a small LED light.
For now, the energy output of the device is just a tiny part of what a solar-cell can produce. Raman sees the device as a complement to solar, providing inexpensive, 24-hour power generation for remote areas of the world- without the need for batteries.
In addition to lighting, Raman says the device could be useful for specialized applications, such as powering wireless sensors and monitoring atmospheric conditions.

【推荐3】Are you a media addict who would go mad after two hours without TV, friend requests, exciting online games and your mobile—or would you easily survive?
Recently, university students around the world were asked to volunteer in a global experiment called Unplugged. It was designed to see how young people would react if they were asked to observe a total media ban by unplugging all forms of media devices for 24 hours.
Unplugged is being run by Dr Roman Gerodimos, a lecturer in Communication and Journalism at Bournemouth University. The experiment is now over but he doesn't yet know the full findings. However, during the experiment, Dr Gerodimos said there were already signs of how much the exercise affected volunteers. He said: “They’re reporting withdrawal symptoms, overeating, feeling nervous, isolated and disconnected.”
During their 24-hour painful experience, three of the experiment’s guinea pigs had to endure one intrusion from the media: a BBC reporter plus cameraman who followed them around for the day. They were asked to write down 100 lines about their day offline, but of course, they all waited until the next day when they had access to their laptops.
Elliot Day wrote: “Today, my whole morning routine was thrown up into the air. Despite being aware of the social importance of the media, I was surprised by how empty my life felt without the radio or newspapers.”
And Charlotte Gay wrote: “I have to say the most difficult item for me to be without has been my mobile; not only is it a social tool, it's my main access point of communication.”
Earlier in the year, a UK government study found that in the UK we spend about half our waking hours using the media, often plugged into several things at once. And a recent study by Nielson found that on average, US teenagers send and receive over 3,000 texts per month-that's about six texts per waking hour.
