福州西湖国际学校于4月16-18日举行了2025年科学实验展，各年级学子出色的创新力、科学思维与创造力在此展露无遗。探入小学生好奇求知的心灵、细品中学学子详尽的实验，今年科技展可谓集探索与发现于一体的盛大庆典。

FLIS proudly hosted its 2025 STEAM Fair from April 16-18, showcasing the outstanding innovation, scientific thinking, and creativity of our students across all grade levels. From the curious minds of our youngest learners to the detailed experimentation of our MYP students, this year’s fair was a remarkable celebration of inquiry, discovery, and collaboration.

PYP Highlights 初中部亮点

小学学子动手探究与缜密思考的能力给评委留下了深刻印象。三年级学子Tim的实验“哪种冰最坚固？（Which Ice is Strongest?）”夺得第一名，同样来自三年级的Jeremy获得第二名，他通过“哪种液体能让鸡蛋上浮？（Which Kind of Liquid Can Make an Egg Float?）”实验探讨了密度；获得第三名的是五年级的Jan, Zoe, Elisa, Michael和Noah，几位学子设计实验了解了潜水艇的沉浮原理。

Our PYP students impressed the judges with hands-on investigations and thoughtful questions. Congratulations to our 1st place winner from Grade 3, Tim, with the exciting experiment “Which Ice is Strongest?”. In 2nd place, Grade 3 student Jeremy explored density with “Which Kind of Liquid Can Make an Egg Float?”, while 3rd place went to Grade 5 students Jan, Zoe, Elisa, Michael, and Noah for their creative engineering in “Submarine” design.

MYP Highlights 中学部亮点

初中部各年级学子的研究和实验也极为精彩。教师基于IB-MYP项目学习评分规则进行打分，获得6、7 或 8 分的学子将获得本次科学展的优秀证书。

Across the MYP grades, students brought impressive research and experimentation to life. For MYP students, projects were evaluated using the IB scoring, and those scoring 6, 7, or 8 will receive STEAM Excellence Certificates for their achievement.

6分展板 Awarded Projects – 6's

Aina同学的自动洒水装置是获得6分的优秀展板之一。养护植物少不了要定期浇水，但时不时的，或许你也想偷偷懒？Aina同学设计的自动洒水装置可以根据土壤湿度释放水分。让我们为省时省力的科技欢呼吧！

Among the many standout projects that received a 6 was MYP3.1 Aina’s Automatic Irrigation System.  Have you ever wanted to not have to water your plants all the time?  Aina was able to engineer a sprinkler that would respond to the levels of moisture in the soil. Let’s hear it for time saving technology!

另一个吸引眼球的展板是 MYP4 Cici, Wendy, Alicia和 Reetta同学的磁悬浮列车。几位同学观看磁悬浮列车驰骋的视频后获得灵感，用木块和磁铁复制了一辆磁悬浮列车。她们制作的装置不仅能悬浮，还能载物！如魔法一般——但却是科学的！MYP5 Vindy和Tina同学的颜料实验也很有趣。Vindy同学是一位出色的艺术家，她的小组一直在寻找最佳艺术效果：哪种矿石做出来的颜料效果最好？是黑曜石、蓝顽火辉石还是蓝方解石？在杵臼内进行多次（非常多次！）研磨碾压后，两人发现，还得是蓝方解石啊！其他获得6分的优秀作品如下：

Another standout was MYP4 Cici’s, Wendy’s, Alicia’s, and Reetta’s Floating Maglev Train. Inspired by watching videos of magnetic trains zooming across the landscape this team was able to engineer a facsimile made out of wooden blocks and magnets. It was able to float and to carry payloads! Just like magic- but science!  Another standout was MYP5 Vindy’s and Tina’s Best Pigment Materials. Vindy is a very good artist and her team sought to see whether obsidian, Blue Enstatite or Blue Calcite would produce the best result for artistic endeavors. After much (much!) grinding and mashing with the mortar and pestle, they determined that Blue Calcite was the winner! The rest of the outstanding projects that received 6’s are as follows:

7分展板 Awarded Projects – 7's

在众多获得 7 分的优秀展板中，MYP2 的 “饮料与牙齿健康（Drinks and Tooth Health） ”展板值得一提，实验由 Steve, Jason, Will 和 Steven 同学共同完成。大多数学子都喜欢喝可乐等含糖饮料，但我们的牙釉质是否经得起摧残？这一组同学试图找出对牙釉质伤害最大的饮料：是可口可乐、百事可乐还是橙汁？他们用鸡蛋壳代替牙齿进行实验，确定了可乐实际上是这三种饮料中对牙釉质伤害较大的。同学们，平时别忘了刷牙、使用牙线哦！

Among the many standout projects that received a 7 was MYP2’s Drinks and Tooth Health by Steve, Jason, Will, Steven.  Most students love to drink Cola and other sugary drinks. However, this team sought to determine which drink, Coke, Pepsi, or orange juice would pose the most damage to unsuspecting enamel! Using eggs shells as a substitute for teeth the team determined that Coke was actually the most detrimental drink of the three.  Don’t forget to brush and floss!

MYP3.1 的Juto, Afanda和Peter对炸鸡产生了浓厚的研究兴趣。这组同学想找出哪种配料组合调制的面衣能做出最脆的炸鸡。经过多次艰辛实验测试，他们最终确定，比起面包糠，还是面粉和水的老配方能做出更酥脆的炸鸡。MYP3.2 Happy, Dylan 和 Angela 同学的洗手液效果实验是另一亮点。哪款洗手液抗菌效果更佳？这组同学对比了蓝月亮和舒肤佳两个牌子的产品。经过多次洗手、显微镜观察，他们最终确定蓝月亮牌洗手液杀灭的细菌最多——细菌王国抵抗无效，一败涂地！

Another standout was MYP3.1’s Crunchy Fried Chicken by Juto, Afanda, and Peter, This team wanted to find out which combination of ingredients would make the crunchiest fried chicken. After many grueling experiments and testing it was determined that the old standby of flour and water and not a toast coating produced the best results. Another standout was MYP3.2’s Sanitizer Effectiveness by Happy, Dylan and Angela. This team wanted to know if Blue Moon or Safeguard antibacterial was the most effective. After many hand-washings and microscope viewings it was determined that Blue Moon killed the most bacteria- take that Kingdom Prokaryote!

最后， MYP4 Olivia和Henry同学的展板“音调与狗狗指令（Tone and Dog Commands）”实验也大获好评。两位同学就语音语调如何影响我们的狗狗朋友展开了精彩调查。他们发现，用哄劝的声音和狗狗说话时，效果最佳！其他获得 7 分的优秀作品如下：

Finally we have MYP4’s Tone and Dog Commands by Olivia and Henry. These two did a fantastic investigation into how tones affect our canine friends. They determined that a coaxing voice does indeed produce the best results. The rest of the outstanding projects that received 7’s are as follows:
