Five years ago, when I taught art at a school in Seattle, I used Tinkertoys as a test at the beginning of a term to find out something about my students. I put a small set of Tinkertoys in front of each student, and said: "Make something out of the Tinkertoys. You have 45 minutes today - and 45minutes each day for the rest of the week."

    A few students hesitated to start. They waited to see the rest of the class would do. Several others checked the instructions and made something according to one of the model plans provided. Another group built something out of their own imaginations.

    Once I had a boy who worked experimentally with Tinkertoys in his free time. His constructions filled a shelf in the art classroom and a good part of his bedroom at home. I was delighted at the presence of such a student. Here was an exceptionally creative mind at work. His presence meant that I had an unexpected teaching assistant in class whose creativity would infect（感染）other students.

Encouraging this kind of thinking has a downside. I ran the risk of losing those students who had a different style of thinking. Without fail one would declare, "But I'm just not creative."

"Do you dream at night when you're asleep?"

"Oh, sure."

"So tell me one of your most interesting dreams." The student would tell something wildly imaginative. Flying in the sky or in a time machine or growing three heads. "That's pretty creative. Who does that for you? "

"Nobody. I do it."

"Really-at night, when you're asleep?"

"Sure."

"Try doing it in the daytime, in class, okay?"

    A list of volunteer activities:

    Paint houses: Do you enjoy making art? If so, this volunteer opportunity might be just right for you! Happy Homes is a local organization that provides home repairs for needy people in the form of painting. For elderly or physically disabled people who cannot do repairs to their homes, Happy Homes provides volunteer painters to repaint old homes; outside or in. Happy Homes also provides painters to create beautiful wall paintings inside schools or community centers.

    Plant flowers: Do you enjoy being outside in nature? City Parks Association has many great opportunities for people who love to be outdoors. Help plant flowers and bushes in city parks; help lay paths at Cave Springs Park, or help pick up rubbish around the river banks. These activities are very active, so remember to be prepared with plenty of drinking water!

    Read to children: Do you enjoy working with young children? Do you like books? Love and Learning is an organization that provides volunteers to help children with learning disabilities. Read books out loud to groups of children four to six years old, or read one-on-one with struggling readers seven to eight years old.

    Play with animals: Do you love animals? Lovely Friends is an organization that visits local animal shelters and provides volunteers to spend time with the animals while their cages are being cleaned. Play with puppies, snuggle with cats, or hand-feed rabbits.

    Better known by his stage name Kun, Cai Xukun is, without a doubt, one of the most popular stars in China.

    On July 26, the 21-year-old dropped his new single Young. Within just 20 seconds, it reached 1 million views and in only 3 days topped the music charts of Tencent's QQ music.

    Cai wrote the song by himself to share his understanding of modern-day youth. The singer has mixed R&B with electronic music to make his new beat cheerful. One reviewer wrote on QQ Music: "When you listen to the song, you just seem to go back to youth again."

    August 2 is Cai's birthday, and the song was a gift to himself. The singer hopes that he can always have the courage to follow his love of music, ignoring what anyone says. "My works are like my children and I have put my best effort into them. I want every piece of my work to have my own spirit in it. I feel more enjoyment when I am performing my own work." He told the Global Times.

    To find new inspiration, Kun attends different kinds of musical performances－from festivals to opera houses. "I just like to do everything, all for my music, all for my art," he told i-D.

    With talent and dedication(专注) to music, Cai is expected by many to make his mark in the competitive Chinese music industry.

    Scientists Diego Kersting and Cristina Linares have found that some coral species are able to recover from harmful warming events through a unique survival strategy (策略)—known as "rejuvenescence" (新生)—among corals in the Mediterranean Sea. The findings represent some rare good news for corals around the world, which are facing numerous severe threats—most notably, climate change.

    "The main threats are climate change, overfishing, pollution and coastal urbanization," Kersting said. "But currently, climate change is probably the one causing the most coral cover declines. Warming stresses corals up to a point that may cause death. Some corals bleach (白化) before dying. Other corals do not bleach but die directly." He went on, "Our findings are significant because this survival strategy was only known from fossil corals that existed hundreds of millions of years ago. It is the first time that it has been found in a living coral. Thanks to our findings, we know now that some corals are able to recover, but unfortunately this is not enough in the current climate change context."

    For their research, Kersting and Linares monitored 243 colonies of the endangered reef-building coral Cladocoracaespitosa in Spain's Columbretes Islands Marine Reserve over 16 years, starting in 2002. The monitoring revealed that Cladocoracaespitosa in the Mediterranean uses rejuvenescence to cope with warming events. This process involves the polyps — or the individual coral animals in a colony—shrinking inward and abandoning their skeletons (骨骼) during warm periods, before rejuvenating at a later point. "What happens is that some polyps in a coral colony—sometimes just one— reduces completely its dimensions and partially retreats from its skeleton," Kersting said. "Once the stressful event is over, the shrunken or rejuvenated polyp recovers its size and builds up a new skeleton. Eventually, it begins to reproduce itself through budding and begins to cover the dead colony surfaces."

    He continued, "The results were very surprising because I started to observe colonies that were dead years ago, that were showing living parts many years after their death."

Max Du won the Canada-Wide Science Fair. His project is a drone (无人机) to save people who go into cardiac (心脏的) arrest. Max got the inspiration during Christmas break last year. "I got a toy drone from my parents, but I couldn't fly it because it is snowy." Max said. "So I played with it at home, and it got me thinking how a drone could be used as an indoor robot that could help people."

About 35, 000 people have cardiac arrests in Canada each year. Most of those happen outside of a hospital, of whom fewer than 10 percent survive. Max believed a drone could offer faster support and life-saving medicine, but he had to build it himself to know for sure.

Testing his drone took about six months. Max's parents had to deal with their son's constantly flying and crashing in the home. Every time Max would create an exciting innovation, such as an extendable arm, it would add extra weight to his drone, causing it to break apart. Then Max would have to buy all new parts. Max tested using more lightweight materials until his design was more balanced.

Through trial and error, the 14-year-old boy finally got it right. His drone can open a door handle, fly in the air and then land softly on the ground. A new extendable arm can be released to administer a shot or hand a patient lifesaving medicine. A built-in camera could directly conference with an emergency response team whose members could monitor the patient remotely.

Max plans on applying for a patent (专利) so he can make connections in the health-care industry to get it made for real. He's spent his summer learning about artificial intelligence at California's Stanford University as one of 32 kids selected worldwide. He'll head next to the University of Pennsylvania to take a college-level robotics class before returning to high school in September.

Hannah Ray J was introduced to river surfing after noticing a surfer in the middle of a river in I owa by chance. This arouse a passion that has since defined her life. River surfing, once an exciting activity, is now gaining public attention in the Midwest as an exciting outdoor sport. 

New Whitewater parks and surfing areas are being developed across the region, such as in Nebraska and Iowa, with plans to attract thousands of visitors, boosting local economies. Badfish SUP, a Colorado- based company, reports a significant rise in river surfboard sales since the pandemic(疫情) began. They've even named a board" Wave Farmer" in honor of those living near these new recreation spots. 

The constant waves in rivers, unlike the ocean, allow surfers to practice constantly. Technological advancements have helped transform river surfing from a rare to a mainstream activity. The growing interest is evident in the number of cars at the WOKA Whitewater park in Oklahoma, exceeding expectations. 

WOKA offers rent gear(齿轮) and live webcams(摄像头) to check wave conditions. The community support for such activities is also noticeable, with businesses related to Whitewater activities expanding into the area. Other cities are looking to reproduce these successes with plans for Whitewater parks on their rivers. 

However, challenges remain, including water quality issues, variable river flows, and safety risks associated with fast- moving water. Despite these barriers, river surfing looks set to continue its rise in popularity, offering both thrills and economic opportunities for many communities.
