阳光“吹动”风车

Spin a Wheel With Sunlight!

It’s a beautiful, sunshiny day where we live!
这一天我们居住的地方是多么的阳光明媚啊
It’s a beautiful, sunshiny day where we live!
在这美丽的一天里 我最喜欢的就是温暖的阳光洒在我脸上的感觉
My favorite thing about a nice day like this is the feeling of the warm sun on my face.
My favorite thing about a nice day like this is feeling the warm sun on my face.
但是你知道太阳的温暖除了让人感觉美好外还可以作为一种能量吗
But did you know aside from just feeling nice, the sun’s warmth is a kind of energy?
But did you know, aside from just feeling nice, the sun’s warmth is a kind of energy?
(Squeaks squeaks)
-[吱吱 吱吱]-你是对的 吱吱
– [Squeaks squeaking]- You are right, Squeaks!
You’re right, Squeaks!
来自太阳的光能和热能可用于许多东西
We use energy from the sun’s light and heat for a lot of things!
We use energy from the sun’s light and heat for lots of things!
你使用的来自太阳的能量被称作太阳能
When you use the energy from the sun, that’s called solar power.
When you use the energy from the sun, that’s called solar power, because “solar” is
因为”solar(太阳)”这个词是另一个用来表达来自太阳的物质的词语
Because “solar” is just another word for things that come from the sun.
just another word for things that come from the sun.
你有注意到屋顶上一些大的平的黑色长方形平板吗
Have you ever seen a bunch of big flat black rectangles on top of a building?
Have you ever seen a bunch of big, flat, black rectangles on top of a building?
这些就是太阳能板 它们接收太阳能再将其转换为电能
Those are solar panels. They take sunlight and turn it into electricity.
Those are solar panels.
They take sunlight and turn it into electricity!
一些人也会聚集热能去保温他们的房子和加热水
Some people also collect the heat from the sun to warm their homes or heat their water.
Some people also collect the heat from sunlight to warm their homes or heat their water.
我甚至制作了一个吱吱去运行太阳能
I even built Squeaks to run on solar power!
I even built Squeaks to run on solar power!
你知道吗 吱吱 这样阳光明媚的天气让我想到了一个绝佳的计划
You know, Squeaks, this warm sunny day got me thinking about a cool project
(Maybe Squeaks is wearing a pair of sunglasses or something)
You know, Squeaks, this warm, sunny day got me thinking about a cool project we can do
我们可以用太阳能来完成这个计划
that we could do it together to use the sun’s energy ourselves.
together to use the sun’s energy ourselves.
Want to try it?
-你想要试试吗-[吱吱 吱吱]
– Do you want to try it out?- [Squeaks squeaking]
[Squeaks agrees]
那好 我们开始做吧
OK, let’s do it!
Okay, let’s do it!
我们准备做一个叫做太阳能气流塔的东西
We’re going to build something called a solar updraft tower.
We’re going to build something called a solar updraft tower.
因为它的名字里有一个”太阳”在里面 所以你应该知道它应该与太阳有关
Since it has the word “solar” in it, you already know that it has something to do with the sun.
Since it has the word “solar” in it, you already know that it has something to do with
the sun.
“updraft”的意思就是风随着空气上升
“Updraft” just means a kind of wind with air moves up.
“Updraft” just means a kind of wind where air moves up.
And you know what a tower is!
你应该知道塔是什么吧 那么你能猜出我们的太阳能气流塔是用来做什么的吗
And you know what a tower is! So can you guess what our solar updraft tower will do?
So, can you guess what our solar updraft tower will do?
It’ll take sunlight, and use that to make air move upward through the tower and spin
它会吸收并利用阳光让空气在塔内上升从而转动风车
It’ll take sunlight and use that to make air move upwards through a tower and spin a paper pinwheel.
this paper pinwheel!
你也可以试着在家里做这个东西
You can try this project at home, too.
You can try this project at home, too.
首先 你需要三个切掉顶部和底座的干净易拉罐
First, you’ll need three clean tin cans with the tops and bottoms cut off.
First, you’ll need three clean tin cans that with the tops and bottoms cut off.
Make sure to get a grownup to open the cans!
你同样需要一些胶带 一段像回形针一样的电线和一些图钉
You’ll also need some tape, a piece of wire like a paper clip, some thumbtacks,
You’ll also need some tape,
a paper clip,
a thumbtack,
和两本相同尺寸的书 它们一定要是非常大的书
and two books about the same size. They need to be pretty big books.
and two books that are about the same thickness.
They should be pretty big books.
然后 让大人帮你剪一些每边约15厘米或6英尺大小的正方形
Then, ask a grown-up to cut a piece of paper into a square: 15 cm or about 6 inches on each side.
Then, ask a grownup to cut a piece of paper into a square, 15 centimeters — or about
6 inches — on each side.
当然 最重要的是你需要一个晴天
And most importantly, you need a sunny day!
And, most importantly, you need a sunny day!
现在我们准备去建造这个塔了
Now we’re going to build the tower.
Now we’re going to build the tower.
First, stack up the cans and tape them together really well.
首先把这三个罐子叠起来并粘起来并保证它们粘得非常好
First, stack up of the cans and tape them together really well.
然后将电线或是回形针折成拱形 像这样的 然后把它粘在塔罐子的顶端
Next, bend the wire, or a paperclip, into an arch shape like this, and tape it to the top of the tower of cans.
Next, bend the paperclip into an arch shape like this, and tape it to the top of the tower
of cans.
然后 让大人帮你把图钉用胶布到固定拱形电线上 就像是这样
Then, get a grown-up to help you attach the thumbtack to the top of the wire arch with tape, like this!
Then, get a grownup to help you attach the thumbtack to the top of the paper clip shape
with tape, like this!
现在 我们要叠一个纸风车
Now, we’ll fold the pinwheel.
Now, we’ll fold the pinwheel.
拿出你的正方形纸 让大人帮你按着每个角的对角线的方向剪
Grab your square paper and have a grown-up help you cut diagonally from the corners.
Grab your square paper and have a grownup help you cut diagonally from the corners.
Don’t cut all the way through the paper, though!
不要将纸沿着对角线都剪穿 剪到离中间有一段距离就好了
Don’t cut all the way through the paper though! Stop cutting about this far from the middle.
Stop cutting about this far from the middle.
等到这些角都剪好了 把它们像这样对折起来 然后它们粘到中心
Once all the corners are cut, fold them like this, and tape them together in the center.
Once all the corners are cut, fold them like this, and tape them together in the center.
Done!
之后让大人用图钉把风车固定在罐子上 最后 我们的塔就做好啦
Then, get your grown-up to stick a pinwheel onto the pointy end of the tack. And our tower is ready!
Then get your grownup to stick the pinwheel onto the pointy end of the tack.
Our tower is ready!
我们现在需要做的就是把它放在书上
All we have to do now is to put the can-tower on top of the books,
All we have to do now is put the can tower on top of the books, so there’s a gap at
这样在它的底部就会有一个缺口然后把它放在靠近太阳直接照射到的窗户旁
so there’s a gap at the bottom, and set the whole thing near a window where there’s direct sunlight.
the bottom, and set the whole thing near a window, where there’s direct sunlight — so
这样太阳就能穿过窗户直接照射进来
So the sun is shining straight through the window.
the sun is shining straight through the window.
And now we wait.
这个过程需要一定的时间[滴滴]这主要取决于这个地方是否足够温暖和晴朗
It might take a while, [ticking] depending on how warm and sunny it is where you are.
It might take a while, depending on how warm and sunny it is where you are, so be patient
所以你要足够耐心 不时地确认你的塔
So be patient, and check on your tower every now and then.
and check on your tower every now and then.
不久后 就会有很棒的事发生 哇 风车在转动啊
After a while, something really cool will happen. Wow, the pinwheel is spinning!
After a while, something really cool will happen!
Whoa!
The pinwheel is spinning!
(Squeaks squeaks)
-[吱吱 吱吱]-这不是魔术 吱吱 这是科学
– [Squeaks squeaking]- It’s not magic, Squeaks! It’s Science.
It isn’t magic, Squeaks!
It’s science!
当阳光照在这些罐子上时 它们就会变热
When the sun shines on the cans, they get hot.
When the sun shines on the cans, the cans get hot.
一些热量就会通过金属线传输到罐子的底部
Some of their heat travels through the metal to the inside of the cans,
Some of that heat travels through the metal to the inside of the cans, so there’s hot
所以在塔的内部就会聚集一些热空气 然后热空气就会上升
so there is hot air inside the tower. And hot air rises.
air inside the tower.
And hot air rises.
Squeaks, do you remember when we learned about how hot air balloons work?
吱吱 你还记得我们上次所学的热气球的工作原理吗
Squeaks, do you remember when we learned about how hot-air balloons work?
-[吱吱]-真棒 这个塔和热气球其实是同样的原理
– [squeaking] – Well, this is the same kind of idea.
Well, this is the same kind of idea.
空气看起来似乎并没有什么组成成分
Air might seem like it’s made of nothing,
Air might seem like it’s made of nothing, but it’s actually made of lots of little
但实际上它是由许多微颗粒组成的 只是因为太小而不能用肉眼看见
but it’s actually made of a lot of little tiny particles, way too small to see.
tiny particles, way too small to see.
当阳光使塔内部的空气加热
When sunlight heats up the air inside our tower,
When sunlight heats up the air inside our tower, the heat makes those tiny particles
热量就会使这些微型颗粒开始剧烈运动并不断扩散
the heat makes those tiny little particles start to bounce around faster and faster, and spread out.
start to bounce around faster and spread out.
更热的空气运动扩散的更快像这样就会向上扩散
Warmer air that’s more spread out like that will move upwards,
Warmer air that’s more spread out like that will move upward so it’s on top of the cooler
所以顶部的冷空气相对运动的就很慢
so it’s on top of the cooler air that’s less spread out.
air that’s less spread out.
这就好比塑料勺子为什么会浮在水面
It’s a lot like how a plastic spoon will float on water.
It’s a lot like how a plastic spoon will float on water!
对于塔而言 就是指当罐子里空气被太阳光加热
In our tower, that means that when the sun warms up the air inside the cans,
In our tower, that means that when the sun warms up the air inside the cans, the warmer
热空气会向上运动从而推动风车的运行
the warmer air will move upwards through the tower and make the paper pinwheel spins as it passes by.
air will move upward through the tower and make the paper wheel spin as it passes by.
然后冷空气会通过底部的缺口进入到罐子里然后加热上升
Then, cooler air comes in through the gap of the bottom of the tower, gets heated up, and rises.
Then cooler air comes in through the gap on the bottom of the tower, gets heated up, and
rises, so there’s a constant flow of warm air that keeps the wheel spinning.
所以就会有源源不断的热空气流动 使得风车不停的转动
So there’s a constant flow of warm air that keeps the wheel spinning.
We’ve made a solar updraft tower.
我们制作了一个太阳能气流塔哦
We’ve made a solar updraft tower!
There are some places in the world where they actually use giant solar updraft towers to
世界还有很多地区也在利用巨大的太阳能气流塔去发电
There are some places in the world where they actually use giant solar updraft towers to generate electricity.
generate electricity!
So the next time you feel the warm sun on your face, remember that it’s more than
所以下次当你在感受到阳光的温暖的时候 要记得你太阳的温暖不仅仅是一种美好的感受
So the next time when you feel the warm sun on your face, remember that it’s more than just a nice feeling.
just a nice feeling — sunlight is a powerful and useful source of energy.
太阳光是一种有着无限潜能和利用价值的能源
Sunlight is a powerful and useful source of energy.
这也是吱吱用来到处跑动的能源
It’s the same energy Squeaks uses to get around!
It’s the same energy Squeaks uses to get around!
