The Singapore Science Centre, situated on a sprawling six-hectare site in Jurong, offers a captivating way to explore the wonders of science and technology. Here, visitors can engage with interactive exhibits that make learning both fun and memorable. Clap your hands, and colorful bulbs will light up; spin a wheel, and it will activate a fan. This engaging environment sparks curiosity and fuels the imagination of both children and adults.
The centre boasts more than four hundred exhibits across various fascinating topics, including solar radiation, communication, electronics, mathematics, nuclear energy, and evolution. These exhibits are designed to foster interest in science and technology among the public, making the centre a hub for educational exploration.
Notably, it is the first science centre to be established in Southeast Asia. Officially opened in 1977, the centre now welcomes an average of 1,200 visitors daily, highlighting its enduring popularity and educational value.
The exhibits are thoughtfully arranged across four main galleries: the Lobby, Physical Sciences, Life Sciences, and Aviation. To ensure a fresh and engaging experience, the exhibits are renewed annually, encouraging repeat visits. Visitors are encouraged to interact with the exhibits, as opposed to traditional “hands-off” policies in most museums. Here, pushing buttons, turning cranks, or pedaling mechanisms are all part of the fun and learning experience.
The Discovery Centre, added in 1985, is specially designed for children aged three to twelve, providing an exciting space for young minds to explore and experiment. Most recently, a stone-age exhibit was introduced, showcasing extinct animals and early human life, offering insights into prehistoric times.
With its interactive displays and immersive environment, the Singapore Science Centre continues to inspire a love for science and discovery, making it an unforgettable destination for learners of all ages.

SCREEN TIME: MENTAL HEALTH MENACE OR SCAPEGOAT?
"Have smartphones destroyed a generation?" Jean Twenge - a psychology professor at San Diego State University - asked in her controversial book, iGen. In the book, she argues that those born after 1995 are facing "a mental-health crisis", and she believes it can be linked to growing up with their noses pressed against a screen. Her newest study provides more support for that connection, showing that teens who spent more than an hour or two a day interacting with their gadgets were less happy on average than those who had more face time with others.
Twenge's conclusions have come up against criticism in the past. Some have accused her work of oversimplifying or overlooking data that may tell a slightly different story. Twenge recognises that her study suggests only a link between screen use and psychological well-being. A possible explanation is that kids are running to their screens to escape from the things in life that are making them unhappy. However, the surveys can't say whether screen time directly changes teens' mental health, the research states.
Philanthropist Melinda Gates, whose three children were also born after 1995, wrote in The Washington Post, "phones and apps aren't good or bad by themselves, but for adolescents who don't yet have the emotional tools to overcome life's problems, they can aggravate the difficulties of growing up."
At the same time, she said, kids are learning on their devices and connecting in novel ways. Other studies have explored the connection between social media and isolation and how "likes" activate the brain's reward centre. Some analyses have found that moderate use of these technologies is not harmful in itself and can even improve children's social skills and build emotional strength.
The word aggravate in paragraph 3 is closest in meaning to ____
Read the following passage about the Science in Service of Humanity and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 31 to 40.
Science has come out of its shell in laboratories to become a powerful force for human advancement. Modern scientific endeavors increasingly focus on addressing real-world challenges affecting communities globally. From developing vaccines that save millions to creating technologies connecting people across continents, science serves humanity in countless ways. This shift represents a fundamental evolution in how we perceive scientific progress—not merely academic pursuit but a practical tool for improving lives and solving pressing problems.
[I] Medical breakthroughs exemplify how science directly benefits humanity. [II] For instance, gene therapy offers hope for those with inherited conditions, while artificial intelligence helps diagnose diseases earlier and more accurately. [III] These advancements didn't happen overnight; scientists had to burn the midnight oil for years before achieving success. [IV] Their perseverance demonstrates that when science targets humanitarian goals, results can transform society profoundly.
Environmental science has emerged as another crucial domain where laboratory work translates into human welfare. Climate scientists provide data informing policy decisions affecting billions. Conservation biologists develop strategies to protect biodiversity, ensuring future generations benefit from natural resources. Agricultural researchers create drought-resistant crops helping communities withstand changing climate conditions. Despite these contributions, environmental science faces challenges including funding limitations, political resistance, and urgency of addressing accelerating climate change. Nevertheless, dedicated scientists continue their work, recognizing environmental health directly impacts human wellbeing.
The future of science in service of humanity looks increasingly collaborative and inclusive. Modern approaches incorporate diverse perspectives, including indigenous knowledge and community participation. Citizen science projects engage non-professionals in data collection, democratizing the scientific process. Open-access publishing makes research findings available to anyone with internet access, not just wealthy institutions. These developments suggest science's greatest potential lies in becoming more accessible and responsive to human needs. As we face complex global challenges, from pandemics to climate change, science serving humanity offers our best hope for a sustainable future.

I was an MBA student in the USA and I lived in the university’s coed dormitory. In my culture, usually, if a woman talks to a man, it is a sign of romantic interest.

In an era of increasing global awareness, debates around sustainable practices such as fair trade, organic farming, and recycling are gaining prominence. Farmers in developing countries are among the most vulnerable people, dependent on world commodity markets, middlemen, and unpredictable weather.
(I)Fair trade arrangements aim to support cooperative groups by guaranteeing prices above the world market rate and additional bonuses. (II) However, critics argue that fair trade may not lift a country out of poverty. (III)They claim that most of the money generated from sales goes to wealthy countries that promote these products. (IV)In fact, only about 5% of the sale price of a fair-trade chocolate bar (retailing for £1.73 in the UK) reaches the poor country.
Another significant trend is the rise of organic food, marketed as being free of chemicals, which appeals to consumers concerned about the dangers of chemicals in food. These chemicals are suspected of causing various health problems, including cancer and developmental issues in children. Despite these concerns, British farmers have not converted to organic farming in large enough numbers to meet the demand. As a result, supermarkets often import organic vegetables from distant countries, contributing to higher greenhouse gas emissions due to transportation. Environmentalists are now urging consumers to buy locally grown vegetables, even if they are pesticide-treated, suggesting a good wash can minimize the risk.
In recent years, a shift has occurred in how we handle waste. Once content to bury it in landfills or dump it at sea, we are now encouraged to recycle and treat waste as a resource. This shift has led to more widespread kerbside collections for various materials like paper, plastic, and metal. However, recycling has unintended consequences. Most of the UK's recyclables are sent to China or India, which incurs additional environmental costs from transportation. In these countries, workers often sort waste under dangerous conditions. Sometimes, materials that are sorted at home still end up in landfills because the market for them fluctuates.
While efforts to promote sustainability are commendable, they require constant evaluation to ensure they truly benefit people and the environment, rather than creating new inequalities or environmental harm.
