2018年4月16日,春“光”映入MYP六年级孩子一双双求知的眼瞳。

南大光学学会6名成员,走进我校,带来一堂精彩纷呈的光学启蒙探究课。

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.

  头脑风暴:光,是什么?

What on Earth is Light Exactly?

“提到光,你能想到什么?”有同学回答出“波粒二象性”,让南大光学学会的成员连连惊叹:“这里的孩子们好厉害,后生可畏。 包/span>

“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”.

孩子们知识面的丰富度也许正是得益于国际课程内容的广度和深度!

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

知识普及:光,有哪些?

What Kinds of Different Light Are There?

主讲老师为大家普及一系列基本的光学知识。

常见的发光材料——硅,光的折射、反射、振动方式以及汇聚与发散,结合生动的演示实验,孩子们听得津津有味,看得非常专注。

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.

 探究实验:光,很神奇!

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

 孩子们都跃跃欲试想要自己动手操作了。

 

 学会成员首先将模拟彩虹形成的装置发给了孩子们,小家伙们拿到材料便迫不及待地观察了起来,连连惊叹原来彩虹就是光的折射现象呀!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.

 在学会老师的带领下,进行了偏振片的滤光实验,光线穿过偏振片后,到达我们眼睛中则会呈现不同的颜色,孩子们通过旋转偏振片的角度可以在完全透明的卡片上观察到几种不同的颜色,引得孩子们边做边感叹: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.

 老师们让孩子们体验液晶片的感温效果。

 将温度不同的物体贴近液晶片,就会呈现不同的颜色,温度越高,液晶片的颜色越接近于蓝色。孩子们将自己的小手贴到液晶片上,顿时一个完整的蓝色掌印便出现在了液晶片上,有学生小脑筋转得飞快,说:“家里的液晶电视屏幕也是这样的!”你看孩子们正争先恐后地在老师的大液晶片上按手。?缺瓤此?氖终谱钊饶兀∧米判∫壕Эㄆ?暮⒆用且卜追自谧约旱氖中、手背甚至是胳膊上做起了实验,想要看看自己身体不同的部位温度有没有不同。

 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.

 春光效应:光,有意义!

 More Than Just Light - A Meaningful Experience for All

 活动很快就结束了,孩子们围着老师久久不肯散去。

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

 此次光学进校园活动让孩子们从实验中观察到了诸多有趣的光学现象,很多孩子已经迫不及待地想要了解更多光学知识,我们也期待光学学会的老师们可以为孩子们带来后续的系列讲座,让孩子们再度探寻神奇的科学世界。

 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.
