学生获奖感言

 

三位获奖学生各自发表了获奖感言，并对研究成果进行总结，聆听他们的分享。

 

 

Angel Huang：

 

“这次科学竞赛让我认识到科学绝非枯燥的学科。设计和制作水藻纸的过程令我深深着迷。这段研究经历让我重新审视自己原本计划在后阶段放弃科学课程的想法，重新点燃了对这门学科的热情。

 

此次获奖也极大增强了我继续深入研究的信心。下一步，我们计划优化已开发的水藻纸制作工艺。我设想深入研究其卓越的吸水特性——若能在此基础上提升材料的韧性与耐久度，同时保持超强吸水性，最终成果或可应用于防洪救灾领域。我们还计划研发水藻基面料，兼顾商业应用与艺术设计，加速推动环保型可再生纺织品的诞生。

 

最后，我衷心感谢这次难得的机会。它让我得以亲身实践那些曾认为只存在于理论中甚至近乎幻想的科学概念。最重要的是，我领悟到：当事情看似不可能时，首先要勇于尝试——未尽全力之前，永不言弃。”

 

This science competition has shown me that science is not merely a dry academic discipline. The process of designing and making algae paper turned out to be highly engaging for me. This research experience has made me reconsider my initial inclination to withdraw from my science classes during AL, reigniting my passion for the subjects.

 

Additionally, winning this competition has significantly boosted my confidence to pursue further research. Moving forward, we plan to refine the algae paper making process we developed. One idea I have is to explore its exceptional water-absorption capacity. Furthermore, if we can enhance its toughness and durability while maintaining this superior absorbency, the resulting material could contribute to flood prevention and relief efforts. We also plan to study the development of algae-based fabric for both commercial applications and artistic design, accelerating the creation of an eco-friendly, renewable, and sustainable textile.

 

Finally, I am deeply grateful for this opportunity. It has allowed me to engage with, and bring to life, scientific concepts I once considered purely abstract or even fanciful. Most importantly, I’ve learned that when something seems impossible, you should try it first—never say “never” until you’ve made the attempt.

 

 

Devin Guan：

 

“这项研究最吸引我的部分在于将传统文化与现代议题相结合。在尝试解决藻类过度繁殖问题的过程中，我们从传统造纸术中汲取灵感，探索利用刚毛藻制作纸张的方法。

 

我由衷感谢学校对我们文化遗产保护意识的培养。老师们始终鼓励我们学习传统文化，并将其创造性转化应用于当代场景。通过持续实验，我们意识到单靠古法往往难以解决现代挑战——创新才是关键。本研究正是通过改良传统造纸技艺并融合藻类特性，践行了这一理念。

 

最后，感谢剑桥国际搭建并推崇这样的竞赛平台。这是我首次完成一项相对严谨的科学研究，在逻辑思维与团队协作方面获得了宝贵锻炼。”

 

The part I enjoyed most about this research was combining classical culture with modern issues. While trying to solve the problem of excessive algal growth, we drew inspiration from classical papermaking and explored ways to make paper from Cladophora.

 

I am also deeply grateful to my school for raising our awareness of cultural heritage. The teachers encouraged us to learn from classical culture and adapt it to modern contexts. Through continuous experimentation, we realized that ancient techniques alone often fail to address contemporary challenges—innovation is key. In this study, we embodied this principle by modifying traditional papermaking techniques and incorporating the unique properties of algae.

 

Finally, I would like to thank Cambridge for creating and honouring this competition. This was my first time completing a relatively rigorous scientific study, which provided invaluable practice in logical thinking and teamwork.

 

 

Andy Bai：

 

“这项研究挑战了我批判性思考与解决复杂问题的能力。实验过程中团队屡遇困境，但通过协作与持续努力，我们成功攻克了所有难题。每位成员都贡献了宝贵想法，经过多次迭代，最终研制出可用于美术课堂的刚毛藻纸张。

 

接下来我们将优化造纸工艺，提高刚毛藻利用率并增强纸张性能。通过这种方式，我们既能将废物转化为宝贵资源，又能解决学校周边水域的藻类过度生长问题。”

 

This science research challenged me to think critically and solve complex problems. Throughout the experiment, our team faced several obstacles, but through collaboration and persistent effort, we successfully overcame them. Each member contributed valuable ideas, and after multiple iterations, we successfully produced algae paper from Cladophora that can be used in our art classes.

 

Moving forward, we plan to refine our papermaking process, optimize the use of Cladophora, and improve the paper’s performance. By doing so, we aim to transform waste into a valuable resource while addressing the issue of algal overgrowth in our school’s surrounding waters.

团队反思

 

团队对于研究成果的思考并没有止步于奖项，经济可行性、工业化适配、生态环境影响等关键问题等待着进一步解决。这一经历深化了学生们对科研本质的理解：科学探索不仅是技术突破，更是对社会责任的践行。

 

 

Team：

 

“我们深感荣幸能参与此次科学竞赛。这段经历不仅拓展了我们的科学知识，更显著提升了解决问题能力与团队协作精神。项目中遇到的挑战促使我们以创造性思维协同合作，最终找到创新性解决方案。

 

我们面临的首个重大障碍是工业造纸设备的缺失。这一局限反而促使我们转向探索传统造纸技艺。然而，藻类纤维与传统造纸材料的显著差异很快显现，使得成纸过程尤为困难。通过对藻类特性的细致分析，我们成功改良造纸工艺以适应这种特殊材料。当缺乏专业检测设备时，我们展现出资源整合能力——利用学校实验室现有工具自主开发测试系统。另一个突破性进展出现在解决纤维结构松散问题时：即便经过充分研磨，我们仍通过反复试验各种填充材料成功增强了纸张结构。

 

尽管取得这些成果，我们清醒认识到仍存在诸多待改进与深入研究的领域。关于藻类纸张的经济可行性及工业化适配等关键问题尚待解答。我们特别关注开发更严格的检测方法，以及优化丝状藻类杂质去除工艺。值得深思的是，大规模采集丝状藻类是否会引发意想不到的生态后果，这需要纳入环境评估范畴。

 

超越造纸领域，我们看到这项研究蕴藏的巨大应用潜力。藻基纸张经漂白杀菌处理后，既可应用于艺术创作领域，也能作为清洁用纸实现实用价值。最具吸引力的或许是开发藻类可持续材料的其他可能性（如织物生产），这将为环保纺织品开辟全新路径。该项目不仅深化了我们对科研的敬畏之心，更展现了创造性问题解决如何催生具有实际应用价值的可持续创新。”

 

We are deeply honoured to have participated in this science competition. Through this experience, we've not only expanded our scientific knowledge but also significantly developed our problem solving abilities and teamwork skills. The challenges we faced throughout the project pushed us to think creatively and work collaboratively to find innovative solutions.

 

One of our first major obstacles was the lack of access to industrial paper making machinery. This limitation led us to explore traditional papermaking techniques instead. However, we quickly discovered that algae fibres behaved quite differently from traditional paper materials, making the paper forming process particularly challenging. Through careful analysis of algae's unique properties, we were able to adapt our papermaking method to better suit this unconventional material. When we found ourselves without specialized equipment to test the paper's properties, we demonstrated resourcefulness by developing our own testing system using the tools available in our school laboratory. Another significant breakthrough came when we addressed the issue of loosely structured fibres, even after extensive grinding of the algae, we solved this by experimenting with various filler materials to reinforce the paper's structure.

 

Despite these accomplishments, we recognize there are still many areas for improvement and further investigation. Key questions remain about the economic viability of algae paper and how it might be adapted for modern manufacturing processes. We're particularly interested in developing more rigorous testing methods and finding better ways to remove impurities from filamentous algae. An important environmental consideration is whether large scale harvesting of filamentous algae might cause unintended ecological consequences that need to be addressed.

 

Looking beyond paper production, we see exciting potential applications for this research. Algae based paper could have artistic uses in craft production, or serve practical purposes as cleaning paper after proper bleaching and sterilization processes. Perhaps most intriguing is the possibility of developing algae into other sustainable materials, such as fabrics, which could open up new possibilities for environmentally friendly textile production. This project has not only deepened our appreciation for scientific research but has also shown us how creative problem solving can lead to sustainable innovations with real world applications.
