［快讯］

5月19日下午，上海宏润博源学校第3届科学艺术展在科学楼和科学广场隆重举行！

On the afternoon of May 19th, we observed the grand opening of the 3rd SHBS Science and Art Fair in the Science Building and on the Science Square.‍

本届科学艺术展的科学部分，同学们一共带来了40多个展示项目，涵盖物理、化学、生物、数学、计算机等学科。从最基础的科学原理实验展示和应用，到当下最红火的ChatGPT使用方式的探索和挖掘，内容丰富，令人叹为观止！

Students presented to the science fair a total of over 40 projects covering various subjects such as physics, chemistry, biology, mathematics, and computer science. We were impressed by the substantial contents of their projects which ranged from fundamental science laws, demos of experiments and applications to the exploratory uses of the currently popular ChatGPT.  

除了同学们自己准备的项目外，学校还邀请了SRCC和思楷学术，为同学们带来机器人和基因检测、移液枪实验、葡萄糖检测等平时学习范围内不太容易接触到的科技，为同学们进一步拓宽眼界。

In addition to the projects presented by the students themselves, our school also invited SRCC and Sikai Academic to introduce technologies that are not easily accessible in their regular classes, such as robotics, genetic testing, pipetting experiments, and glucose testing, so as to broaden the students' horizons.  

艺术展部分，除了展示同学们大量的艺术作品外，还现场为同学们进行“海娜绘画”，吸引了大量的拥趸。

In addition to showcasing a large number of artworks by the students at the art fair, "Henna painting" attracted a lot of fans on the spot.

除了全校师生，学生家长及外来嘉宾也兴致盎然地参加了这一年一度科学与艺术的盛宴。

In addition to the entire school's teachers and students, parents of students and some guests also enthusiastically participated in this annual feast of science and art.

难能可贵的是，这些项目还都是同学们因地制宜，就地取材，自己一步一步亲手做出来的。虽然不少项目看起来有些简陋，显得不那么“高科技”，但对于很多同学来说，这是一个启蒙，为他们在科学和艺术的探索中打开一扇大门。

It is rare and commendable that these projects were all done by the students themselves step by step by making use of local resources and materials. Although some projects may look a bit rough and not very "high-tech," they opened an enlightening door for many students so that they would be able to further explore science and art. 

［个别项目聚焦Some Highlights］

“芦丁鸡孵化”实验 "Quercetin Chicken Incubation" Experiment

展会上，三位同学带来了六只小鸡。这是她们半个月前孵化出来的芦丁鸡。她们使用泡沫箱、水袋以及加热装置自制了一个水床孵化箱，并且网购了芦丁鸡蛋进行孵化。孵化过程异常艰辛，稍有不慎便会“翻车”，需要时刻注意温度与湿度，并且要及时翻蛋和喷水，才能让小鸡顺利破壳而出。

Three students brought to the fair six baby chicks, which were quercetin chickens they hatched half a month ago. They made by themselves a waterbed incubator using a foam box, water bags, and a heating device. They also purchased quercetin chicken eggs online to incubate them. The incubation process was extremely challenging, and any slight negligence could lead to failure. They had to constantly monitor the temperature and humidity, as well as flip the eggs and spray water on them to ensure the chicks are successfully hatched.

在孵化过程中，每隔五天便要使用手电筒照一次蛋，以确认小鸡是否在正常发育。而第五天的照蛋十分重要，因为需要观察鸡蛋内部的情况确认是否有受精卵。同学们怀着忐忑的心情打开了手电筒。令人惊喜的是，15课蛋中有11颗受精了！

While incubating the eggs, students checked the eggs every five days with a flashlight to see if the chicks were developing properly. It was very important to check the eggs on the 5th day because students needed to find out if there were fertilized ovum inside them through observation. Feeling uneasy, students turned on the flashlight. To their surprise, 11 out of 15 eggs were fertilized! 

在之后的十几天，同学们小心翼翼地轮流照看这些鸡蛋，第三次照蛋的时候，蛋已经无法透光了，并且可以看到里面的小鸡在活动，这说明马上就有小生命破壳而出了。终于，在第17天，两只小鸡来到了这个新世界，并且在之后的两天里，陆陆续续的有4只小鸡破壳而出，孵蛋实验圆满完成！

During the next two weeks or so, the students took turns to watch over the eggs carefully. When checking the eggs the third time, the eggs became opaque, and students could see the chicks moving inside, which indicated that they were about to hatch. Finally, on the 17th day, two baby chicks were born in this new world, and during the next two days, four more chicks hatched. The incubation experiment was successfully completed! 

“弹跳泡泡”实验  "Bouncing Bubbles" Experiment

走进化学教室，可以看到里面仙雾弥漫，这是化学班的同学们在做“弹跳泡泡”实验。他们通过这个实验展示了固体形式的二氧化碳的独特特性。使用肥皂溶液制造气泡，并将干冰释放的二氧化碳气体注入其中，这些气泡便可以在气垫上无视重力地漂浮和弹跳。

Entering the chemistry classroom, we found it was filled with mist because students of the chemistry class were doing the "bouncing bubbles" experiment. They demonstrated the unique properties of solid carbon dioxide by making this experiment. They created bubbles using soap solution, and injected carbon dioxide gas released from drikold into them, allowing the bubbles to float and bounce on a cushion of air, regardless of gravity. 

这个现象可以归结为两个关键的科学原理：浮力和莱顿弗罗斯特效应。当二氧化碳气体从干冰中释放出来时，它的密度比周围的空气大。围绕气泡的肥皂膜将二氧化碳气体困在里面，由于二氧化碳和周围空气的密度差异，气泡开始下降。随着干冰气泡的下降，它与房间里较热的空气发生作用，干冰的极低温度使气泡的底面与空气接触后迅速冻结。这个冻结的表面作为一个临时支撑，在气泡和周围的空气之间形成一个绝缘的气体层，这种现象被称为莱顿弗罗斯特效应，允许气泡在这个气垫上漂浮和弹跳。

This phenomenon can be attributed to two key scientific laws: buoyancy and the Leidenfrost effect. When carbon dioxide gas is released from drikold, it’s denser than its surrounding air. The soap film surrounding the bubble traps the carbon dioxide gas inside, and due to the difference of density between carbon dioxide and its surrounding air, the bubble starts to fall. As the dry ice bubbles fall, they interact with the warmer air in the room. The extremely low temperature of the drikold causes the bottom surface of the bubbles to freeze rapidly upon contact with the air. This frozen surface acts as a temporary support, which creates an insulating layer of gas between the bubble and the surrounding air. This phenomenon is known as the Leidenfrost effect, which allows the bubbles to float and bounce on this cushion of gas. ‍

浮力和莱顿弗罗斯特效应的结合导致了干冰气泡的显著行为。这些气泡在很长一段时间内保持漂浮状态，似乎无视重力，直到最终二氧化碳气体消散在周围的空气中，导致气泡破裂。

The combination of buoyancy and the Leidenfrost effect results in the remarkable behavior of drikold bubbles. These bubbles can remain floating for a long time, and appeared as if they defied gravity, until the carbon dioxide gas eventually dissipates into the surrounding air, causing the bubbles to burst. 

“简易爆炸”实验 "Simple Explosion" Experiment

在这次的科学与艺术展上，同学们的各种化学实验为展出提供了不少亮点，例如简易炸弹实验，通过在一个塑料袋中混合小苏打和白醋使得碳酸氢钠与醋酸发生复分解反应，生成醋酸钠与碳酸，而碳酸不稳定会继续分解为二氧化碳和水，二氧化碳使得小塑料袋急剧膨胀从而导致破裂。实验现场十分有趣，引得许多同学与老师闻声而来。

At the science and art fair, students made a variety of chemical experiments which added to its brilliance, such as the simple bomb experiment. After baking soda was mixed with vinegar in a plastic bag, sodium bicarbonate reacted with acetic acid in a decomposition reaction, producing sodium acetate and carbonic acid. The unstable carbonic acid further decomposed into carbon dioxide and water. The rapid expansion of carbon dioxide caused the small plastic bag to inflate abruptly and eventually burst. The experiments were so interesting that they attracted many students and teachers to the spots where they were performed. 

活动结束后，记者找到了他们小组内部的一名队员，采访后发现这个小组在探索的过程中并不是一帆风顺的，在展示之前已经进行了很多次的实验，在这之中，最难的是掌握好白醋与小苏打的混合比例，稍一差错便会导致实验的失败。好在同学们最终克服了这个困难！

After the event, a reporter interviewed a member of the team in charge of the experiment and found that the whole team faced challenges while exploring. They had conducted multiple experiments before demonstrating it at the fair. Among those attempts, the most difficult aspect was to control the mixing ratio of vinegar and baking soda because even a slight mistake could lead to experiment failure. Fortunately, the students eventually overcame this difficulty.‍‍‍

 “温差发电”实验  "Thermoelectric Power Generating" Experiment

温差发电项目引起了记者的注意。该项目通过热水和蜡烛与环境的温差对台灯和电风扇进行发电。所以，即使蜡烛和热水的温度并不是很高，仍能进行发电。在精彩的中英双语的解说后，许多同学与老师清楚地明白了其中的原理。

The thermoelectric power generating project caught the attention of the reporter. This project involved supplying power for a desk lamp and an electric fan by the temperature difference between hot water & a candle and the surrounding environment. Therefore, even though the temperature of the candle and hot water was not very high, they could still generate electricity. After listening to an informative explanation in both Chinese and English, many students and teachers clearly understood the underlying theory.

［后记Epilogue］

训练ChatGPT创作出与玩家互动的游戏，训练Chat GPT成为塔罗牌占星大师为来访者算命盘，AI绘画（Mid- Journey, Stable Diffusion）、3D打印、行走的“烟雾加农炮”、亲手腌制的泡菜、粘土制作的细胞模型……迷人的实验数不胜数。师生们都是意犹未尽，恋恋不舍。

There were countless fascinating experiments, such as to train ChatGPT to create interactive games with players, to train ChatGPT to become a Tarot and astrology expert at reading visitors' fortune, to create AI-generated paintings (with "Mid-Journey, Stable Diffusion"), 3D printing, a walking "Smoke Cannon," handmade pickles, clay-made cell models etc. Both teachers and students were so impressed by those experiments that they felt reluctant to leave.   

遗憾的是，在展出之前，有不少被取消的项目，我们也有幸找到到了负责的同学进行采访：比如滴水成冰实验小组。简单的采访之后我们了解到该项目是通过利用醋酸钠过饱和溶液不稳定的特性，使其在接触到醋酸钠晶体时快速结晶，从而产生了滴水成冰的奇观，只可惜该项目成功率极低，进行多次试验后任只有几次成功，所以很遗憾没能在科学与艺术展中与我们见面。

Unfortunately, quite a few projects had been rejected before the fair was held. However, we were lucky to be able to interview the students in charge of one of such projects, for example, an experiment called "Drops of Water Turned into Icicles”. After a brief interview, we learned that this project involved the rapid crystallization of a supersaturated solution of sodium acetate upon contact with sodium acetate crystals, creating the fascinating phenomenon of drops freezing into ice. However, there was little chance that this experiment would succeed, with only a few successful attempts after multiple trials. Thus, it was a pity that we couldn't showcase it at the Science and Art Fair.  

今年的科学艺术展在往年的基础上更上几个台阶，精彩程度着实让参访的师生们震撼，也会进一步激发同学们对科学和艺术的探索兴趣，激励他们进一步思考自己课堂上所学的知识与现实时间之间的联系，学以致用。

This year's Science and Art Fair made stunning progress on base of  those of the previous years and teachers and students were deeply impressed by it. It is believed that the fair will further inspire students' interest in exploring the fields of science and art, and encourage them to reflect on the connection between what they’ve learned in the class and its real-world applications.
