Angel 班级分享|玩转声音 Sensory Sound

慈溪市安琪儿幼稚园2018-12-14 14:12:25
 


听觉是幼儿感知世界,理解世界的重要途径。中班幼儿对声音的存在越来越敏感,对周围声音世界充满无限好奇,他们说声音是美妙且神秘的。“我们为什么能听到声音?声音是如何传播的?我们能看到声音吗?”带着这些问题,我们K2-Q班的小朋友来了一场玩转声音之旅。



The auditory sense is an important way for children to explore the world. As part of their sensory development, students become aware of different sounds around them. Our K2 children have limitless curiosity for the world around them and they keeping discovering new sounds. They said sound is wonderful and mysterious. How can we hear things? How does sound transmit? Can we find a way to see sounds? K2-Q’s children started to explore different types of sounds.


1.有趣的声音

Interesting Sound


声音从哪里来呢?我们敲一敲,打一打,拍一拍……好多方法都可以让东西发出声音。那大自然有哪些声音呢?孩子们发现不同的东西会发出不同的声音呢!塑料桶会发出闷闷的嗵嗵声;小叶子会发出温柔的沙沙声。

Where does sound come from?  Let's knock, hit, clap. So many ways things let out sounds. What kind of sounds does nature have? We find that different objects can have different sounds. Plastic buckets have a low and deep sound, while leaves could make a gentle rustling sound.



两种物体碰撞在一起,又会擦出什么样的“火花”呢?这样的碰撞会改变之前的声音吗?于是孩子们用小树枝敲打树叶,用小树叶刮擦铁架子,他们惊奇的发现声音的确发生了变化,这是多么有趣的变化啊!

What if two items are hit together? What reaction will they have? Will they change their own sound? And then, children started to tap leaves with a branch, scratch an iron frame with leaves. They are amazed by the changes in sound. How interesting it is!


2.声音的传播 

Transmission of Sound


 


看不见的声音是怎样钻到我们耳朵里的呢?



孩子们决定一起去探索声音在空气里是怎样传播的。我们在纸杯的底部戳上一个洞,用绳子把两个纸杯连接起来。孩子们两人一组,手持传声筒,一个人说,一个人听。

How do these invisible sounds come to our ears?Let's find out how sound is transmitted through the air.We poke a little hole in the bottom of paper cups and use a string to connect two together. Two children, holding the cups, make a pair while one talks in to the cup and the other puts their cup to their ear and listens.


“老师,老师,我听到他的小秘密了!”一阵欢呼声响起,也把声音中的喜悦感进行了传递和分享!在孩子们不断尝试中发现如果想要传声筒传声越清晰,就要将传声筒中间的绳子绷得紧些。

“I hear his little secrets! Teacher! Teacher!”With cheers going up, children also shared and transmitted their happiness.



除了传声筒,孩子们还把绳子和不锈钢汤勺末端系起来,绳子的两端放在耳边,用另外一个不锈钢汤勺敲打它,听听看,声音会不会传到耳朵里?

Children also tried to tie a metal spoon with string and put the two ends of the string in their ear. Listen! Listen! Will the sound come into your ear when you tap the spoon with another spoon?

 


原来声音是由物体振动产生的,通过介质传播。我们听到的很多声音都是由空气传播的。物体在空气中振动,形成波动,靠空气传送到我们耳朵里。

The sound is produced by the vibration of an object and carried by the air. Objects vibrate in the air, form waves and are then transported to our ears in invisible waves.


3.好玩的声音

Funny Sounds


 

孩子们在老师的指导下准备了八个一模一样的玻璃瓶,分别在瓶中注入水,水面由低到高,高度依次相差2厘米。孩子们的“音乐盒”就这样做好了。

Under teachers’ guidance the children prepared eight glass bottles; filled with water, from smallest to largest. The height difference is 2 centimeters in turn. Here we have our music box. The clear and deep sounds make a cheerful rhythm of winter.

 


孩子们迫不及待地敲了起来。“音乐盒”有小秘密呢?瓶子内水位不同,发出的声音也不同,孩子们自由的敲打着瓶身,一个个专注创作的模样,可爱极了!“叮叮咚咚”时而清脆时而低沉的声音也组成了一首冬季欢乐的乐曲。

The children gathered around to inspect the "music box." When the little box is struck lightly with a drum stick ,it makes a tinkling sound. The children play music on the bottles the sounds are as lovely as the children!

 


接着,我们在鼓上撒了很多米。当我们敲鼓时,鼓上的米会弹起来。看到米弹得高高的,孩子们觉得又开心又神奇!打鼓时鼓面振动引起鼓面下的空气也振动,由于鼓的设计使鼓固有频率与鼓面振动频率相近,引起共振(空气共振又叫共鸣),因此声音强度大大增强。而鼓上的米粒随着鼓的振动,也随之跳动。

After experimenting with the music box, we look at drums. Our drums are different from other drums. We sprinkle a lot of rice on the drum. When we beat the drum, the rice on the drum will bounce. The children felt happy and amazed when they saw that the rice was jumping high.  As the drums are hit faster and harder, the vibrations in the air increase (air resonance) causing the rice to jump higher and higher, the volume of sounds becomes louder too (resonance).



自制乐器 

DIY Instruments



认识了声音,玩转了声音,孩子们还想用声音创作一些什么呢?还记得儿时的拨浪鼓吗?一转,两个小木珠就会甩起来敲到鼓面上,传出咚咚咚咚的声音。孩子们先把纸盘的底部涂上自己喜欢的颜色,接着将两个纸盘合在一起,制作成鼓面。然后在两边各戳一个小洞,各自系上铃铛。最后我们又在卡纸上画上自己喜欢的或者是所看到的物体,装饰在我们的纸盘上!自制的拨浪鼓“咚咚咚”的发出声响,孩子们玩着自己做的拨浪鼓,感到格外的开心与自豪!

We have already made some sounds, what else shall we use to make sound?Do you remember the rattles from your childhood? We made our own rattles. First, the children painted two paper plates with their favorite colors and then put them together to make a drum surface. Then they poked a small hole in both sides threaded string through the holes and tied bells on the ends. Finally, they painted decorations on their paper plates. The homemade rattle drums made sounds like " tong tong tong ". When the children play their rattle they feel extremely happy and proud of their creation!



安琪儿的孩子们有着求知欲和探险欲,带着好奇心畅游在这所智慧之园。这次活动中引导幼儿从自然中熟悉的声音入手,发现声音、感知声音,然后启发幼儿探究声音产生的原因,从而迸发创意的火花。

Angel's children are curious and adventurous and they gain wisdom and knowledge from their curiosity. These activities guided the children to start with familiar sounds from nature; to discover and to sense sounds. The children then explored the cause of sound and how it is generated, igniting a creative spark.
