校长说 无处不在的STEAM挑战 Principal's Message Fascinating STEAM Challenge

科学素养的提升是宁波市奉化区诺德安达学校聚焦的一个重要方向。激发孩子们学习科学的兴趣、开拓学生科学眼界及提升他们的综合科学素养，我们责任在肩。学校每周的STEAM课程正是一个切入点。在STEAM教师的带领下，我们看到了一群崇尚科学、善于探究的孩子们，他们的潜力是无限的。这个学期，无论是线上课程还是线下课程，同学们接受了不少科学挑战：

STEAM is a unique and essential program and NAS Ningbo is committed to stimulate children’s interest in science and to improve their scientific perspective. Every week, students actively engage in the STEAM lesson to explore the unknowns, from which we have seen great potential in their future development. For this term, our students have the opportunities to participate in various online and offline STEAM challenges:

挑战一：探究不同反应的能量变化

我们可以通过皮肤感受周边环境的温度变化，但温度变化不是特别明显的时候我们就不能做到准确的判断。FLIR仪器就可以做到精准反应能量变化。在这次疫情中它也发挥了重大作用，比如在人流量密集的机场，它可以快速准确判断人的体温。在STEAM课堂上同学们利用FLIR仪器探究了不同反应的能量变化。当周边环境温度处于较低状态时，画面呈现紫色；当周边环境较高，画面会出现深黄色。同学们可以借助FLIR看到发热物质的运动轨迹。此外同学们探究了不同颜色吸收热量快慢的不同能力。

Challenge 1: Explore the Energy Change in Different Reactions

Although we can feel the temperature change in the surrounding environment through the skin, it would be very difficult when the temperature change is not significant. FLIR, a temperature-testing instrument, is able to respond to energy change precisely. As a result, FLIR has played an important role in this epidemic control and prevention. For instance, body temperature can be easily tested in the crowded airport. In the STEAM lesson, students used FLIR to explore the energy change in different reactions. When the surrounding temperature is relatively in low condition, it appears to be purple, which will turn to deep yellow when it’s high. Students are able to find the movement of the hot material using FLIR. Also, students explored the ability of different color to absorb the heat.

挑战二：Hacking challenge 变废为宝

践行“绿水青山就是金山银山”的绿色发展理念，我们需要将垃圾分类及循环利用坚持到底。同学们这次的挑战是如何变废为宝，把家中可以回收利用的物体再创造变成有用的产品。有同学利用使用过的各种纸张做成了一只美观的笔筒，既实用，又集合了自己的很多“小创意”；有同学做出了一束完美的插花，这是送给父母的礼物。Thomas同学更是利用身边的不再使用的各种材料做出了一只许愿盒，这个具有魔力的小盒是他朝着更大梦想出发的最好证明。

Challenge 2: Turn Waste into Magic

Our environment is facing greater challenge nowadays, which means we must strictly follow the waste separation policy. In this STEAM lesson, students are challenged to make waste into something amazing. One student made a beautiful pen container using waste paper. One student made a perfect bouquet and sent to the parents as a gift. Thomas used various waste materials and turn them into a Wishing Box, which shows his ambition to create something far more great in the future.

挑战三：Makey makey

Makey makey是MIT发明的一款专为 DIY 爱好者设计的便携开发板。STEAM课堂上，同学们将Makey makey连接在苹果上，做成水果电吉他，弹奏出不同的音符；连接好Makey makey的上下左右键，同学们还可以操控起各种小游戏的角色；Makey makey 也可以与Scratch一起使用。疫情期间，同学们学习了简单的Scratch编程，比如用声音、影像等控制程序，用不同乐器演奏音符。同学们编好程序，将USB数据线连接好Makey makey，他们的作品就会呈现。

Challenge 3: Makey makey

Makey makey, designed for DIY enthusiasts, is a development board invented by MIT. Students connected Makey makey to apples and made them into fruit guitar to play different notes. By connecting Makey makey with keyboard, students were able to play different games. Makey makey can also be used with Scratch together. During the epidemic, students learnt basic Scratch programming such as sound and video control programs and using various instruments to play notes. After programming, students connected USB cable to Makey makey and their work was fascinating.

挑战四：水火箭

近日，SpaceX载人飞船成功发射。受到鼓舞的同学们在校园里发射了自己DIY的水火箭。在STEAM课堂中同学们探究了不同水量、不同发射角度以及水火箭重心位置对发射高度的影响。为了更加方便探索各种因素对水火箭上升高度的影响，我们利用无人机拍摄了水火箭的运动轨迹；为了水火箭能够安全降落，同学们为此设计了降落伞，但同学们面临着一个新的挑战 —— 降落伞如何成功打开。同学们将围绕这个问题继续探究。

Challenge 4: Water Rocket

Recently, the spacecraft made by SpaceX was successfully launched, which inspired our students to launch DIY water rocket at school. In order to make it happen, students explored different factors that would affect emission height including volume of water, launching angle, and rocket gravity. Students used drones to better observe the impact of the variables. In addition, students designed parachute to make the water rocket land safely, but they are facing a new challenging---how to open the parachute. Our student will continue to find the answer for this question.

科学无穷尽，我们仍需要不断努力攀登这座高峰；但是，科学在身边，我们需要有敏锐的观察、积极的实践和持之以恒的研究。期待更多的“小科学家”从诺德安达出发，为我们生活的世界注入新的科技发展的动力。

There is no limit in science, and we must keep trying to explore the unknowns. Meanwhile, science is everywhere, and our students need to learned to an observer, a thinker, an inquirer, and to be resilient. We look forward to seeing more and more “Little Scientist” start their journey at NAS Ningbo and make contribution to our society in the future.
