春“光”入校園 A Bright Spring Day at JGCS

2018年4月16日,春“光”映入MYP六年級孩子一雙雙求知的眼瞳。

南大光學學會6名成員,走進我校,帶來一堂精彩紛呈的光學啟蒙探究課。

On the 16th of April 2018, students in grade 6 of our MYP were treated to a a spectacular inquiry-based class by six members of the Optics Students Association of Nanjing University.

  頭腦風暴:光,是什么?

What on Earth is Light Exactly?

“提到光,你能想到什么?”有同學回答出“波粒二象性”,讓南大光學學會的成員連連驚嘆:“這里的孩子們好厲害,后生可畏??!”

“What do you think of when I say the word “light”? Our visitors asked. They were in for a shock when some students gave the answer: “it’s a wave-particle duality”.

孩子們知識面的豐富度也許正是得益于國際課程內容的廣度和深度!

It seems as if our students really are reaping the benefits in both breadth and depth that come with international education.

知識普及:光,有哪些?

What Kinds of Different Light Are There?

主講老師為大家普及一系列基本的光學知識。

常見的發光材料——硅,光的折射、反射、振動方式以及匯聚與發散,結合生動的演示實驗,孩子們聽得津津有味,看得非常專注。

The main speaker at the event performed a number of experiments for us, in the process introducing a range of basic scientific principles including showing the light-giving material, silicon, showing the refraction, reflection, vibration, convergence and diffusion of light. The students watched intently, with interest writ upon their faces.

 探究實驗:光,很神奇!

 Inquiry-Based Experiment: “Behold the Wonders of Light!”

 孩子們都躍躍欲試想要自己動手操作了。

 

 學會成員首先將模擬彩虹形成的裝置發給了孩子們,小家伙們拿到材料便迫不及待地觀察了起來,連連驚嘆原來彩虹就是光的折射現象呀!The kind people at OSANJU had brought along a number of apparatus that mimic the light of a rainbow. The students were itching to have a try for themselves, amazed to find out that a rainbow is simply the result of light refraction.

 在學會老師的帶領下,進行了偏振片的濾光實驗,光線穿過偏振片后,到達我們眼睛中則會呈現不同的顏色,孩子們通過旋轉偏振片的角度可以在完全透明的卡片上觀察到幾種不同的顏色,引得孩子們邊做邊感嘆:好神奇!Next up, the students did a filtration experiment used polaroids. As light passes through the polaroid, it alters the angle of the wave, therefore changing the colour. The students expressed their awe at being able to witness such a range of colours on an otherwise transparent object.

 老師們讓孩子們體驗液晶片的感溫效果。

 將溫度不同的物體貼近液晶片,就會呈現不同的顏色,溫度越高,液晶片的顏色越接近于藍色。孩子們將自己的小手貼到液晶片上,頓時一個完整的藍色掌印便出現在了液晶片上,有學生小腦筋轉得飛快,說:“家里的液晶電視屏幕也是這樣的!”你看孩子們正爭先恐后地在老師的大液晶片上按手印,比比看誰的手掌最熱呢!拿著小液晶卡片的孩子們也紛紛在自己的手心、手背甚至是胳膊上做起了實驗,想要看看自己身體不同的部位溫度有沒有不同。

 When placing materials of differing heat next to liquid crystal chip, the colour will change. The higher the temperature the more blue the light will become. When the students touch it, it will leave behind a warm blue colour. You could see some of the students heads moving as they exclaimed: “Oh, my LCD TV at home also does this!” Students could be seen competing to see whose hands are the warmest by producing the darkest shade of blue. The students when went on to experiment with different parts of their arms to see if it changed the effect.

 春光效應:光,有意義!

 More Than Just Light - A Meaningful Experience for All

 活動很快就結束了,孩子們圍著老師久久不肯散去。

 Before we knew it, the event was drawing to a close, with the students reluctant to say goodbye to our guests.

 此次光學進校園活動讓孩子們從實驗中觀察到了諸多有趣的光學現象,很多孩子已經迫不及待地想要了解更多光學知識,我們也期待光學學會的老師們可以為孩子們帶來后續的系列講座,讓孩子們再度探尋神奇的科學世界。

 In this event our students had the chance to witness firsthand many natural phenomena related to the field of optics. Many students are looking forward to next opportunity to learn more about this fascinating topic. We also look forward to any future opportunities to work together withOSANJU. We would like to take this opportunity to thank them for their visit to our school and guiding them around the world of light.
