打一口你自己的井吧

Make Your Own Well! | Science Project for Kids

看过来!
Check it out!
吱吱和我建了一口我们自己的井!
Squeaks and I built our own well!
井就是你可以用来从地下深处取水的东西
A well is something you can use to get water from deep under the ground.
福特家已经有一个了
The Fort already has one,
但我们想做一个小一些 工作原理相同的版本
but we wanted to make a smaller version that works the same way,
用科学把水从一处带到另一处
bringing water from one place to anotherusing science.
你也可以做一个!
And you can make one, too!
我们将向你展示我们是如何做的 以及它的工作原理
We’ll show you how we did it, and why itworks.
吱吱 你准备好了吗?
Are you ready, Squeaks?
[吱吱肯定地回应]
[Squeaks squeaks affirmatively]
你所需要的是一个干净的杯子或罐子
All you’ll need is a clear cup or jar,
一些石头 水
some rocks, water
一个泵盖 比如皂液瓶上的
A pump-top, like from a bottle of soap
以及一个大人来帮助你
And a grown-up to help you out.
如果你想 你也可以在水里加入食用色素
If you want, you can also add food coloring to the water
这样你就更容易看到
so you can see it more easily.
吱吱 我们这次应该用什么颜色呢?
What color should we use this time, Squeaks?
[吱吱回答]
[Squeaks answers]
哦真是个好提议!
Ooh Great suggestion!
我们要用天蓝色 好的
We’ll use Sky Blue! Okay,
现在我们准备好要开始了 首先
now we’re ready to start. First,
将你的石头放进你的杯子或罐子里
place your rocks in your cup or jar,
直到半满
until its about halfway full
现在填入半杯水 现在我们要加食用色素了
And now fill it half way full of water And now we’ll add the food coloring
这个杯子充当土地
This cup will act like the earth,
有水藏在地下深处的石头和泥土之间
with water hiding deep underground between all of the bits of rock and dirt.
确保已经把你泵上的香皂像我们一样洗干净了
Make sure to wash all the soap off your pump like we have
并把它放进罐子里
and put it in the jar
让管子部分接触水
So that the pipe part touches the water.
好了吱吱 现在我们要让水泵注水了
OK, Squeaks, now we have to prime the pump.
其实就是用它抽几次水
That just means pumping it a few times,
直到有足够的水在
until there ’ s enough water inside the smaller
顶部的小部分里 也就是储存部分 来让它运作
section at the top, called the storage chamber, for it to work.
为了确保我不会搞得一团糟
To make sure I don ’ t make a mess,
我要先在我的水泵下放一个杯子
I ’ m going to put a cup under my pump first
当我按压泵时 会挤出一些空气
When I push down on the pump, it forces some air out.
然后当我放开时
Then when I let go,
它将一些水上升至管子进入储存器里
it pulls some of the water up through the pipe and into the storage chamber.
这很像吸一根吸管
It ’ s a lot like sucking on a straw,
只不过你是在用水泵吸而不是你的嘴
except you ’ re doing it with the pump instead of your mouth.
随着我们一直用泵吸水
As we keep pumping,
越来越多的水进入了管子 当储存器
more and more water goes up into the pipe, and when the storage chamber
满了时 就意味着水泵已经准备好了
is full, that means the pump is primed.
在之前 当我们向下按泵时 空气出来了
Before, when we pushed down on the pump, aircame out.
但现在它已经准备好了 让我们看看会发生什么
But now that it’s primed, let’s see whathappens.
看啊 我们创造了我们自己的井
Look at that, we’ve created our very ownwell!
[吱吱]
[ Squeaks points out that they don’t need to pump the Fort’s well to make it work ]
观察的真好 吱吱
That ’ s a great observation, Squeaks.
我们不需要用我们的手来抽福特的井
We don ’ t need to pump the Fort’s well with our hands
从水管里取水
to get water from the sink.
这很好 因为这将是大量的工作
Which is nice, because that would be a lotof work!
相反的 很多井用电动泵来做相同的工作
Instead, many wells use an electric pump to do the same job.
不像有些人手动从井里抽水
Instead of someone pumping the well by hand,
用相同的动作将水抽入管子再进到储存器里
a machine does it automatically, using the
机器可以自动完成
same motions to pump water up through the pipes and into the storage chamber.
只要储存器一满
As long as the storage chamber stays full,
每当我一打开连接储存器的旋塞
whenever I turn on a faucet that ’ s connected to the chamber
水就会出来
water will come out.
这意味着与其每当我需要水时就出去从井里抽水
This means that instead of going out to pump a well whenever I need water,
我可以让一个机器在我做其它事时来完成它
I can have a machine do it while I do other things,
就像我和我最好的小伙伴的实验一样
like experiments with my best buddy.
[吱吱问是谁]
[Squeaks checks who that is]
当然是你啦 吱吱
Of course that’s you, Squeaks!
我喜欢和你一起学习科学和机器
I love learning about science and machineswith you.
我们下一次试什么呢?
What should we try next?
我们要不要用我们的井来抽点什么比如果汁或牛奶?
Should we use our well to pump something like juice or milk?
你觉得它可以用来抽一些稠的东西比如糖浆吗?
Do you think it’ll work with something thicklike syrup?
如果你自己尝试了
If you try this out for yourself,
告诉我们你从你的实验学到了什么
let us know what you learn from your experiments!
让一个大人帮助你在下面留下评论
Ask a grown-up to help you leave a comment below,
或给我们寄邮件 kids@scishow.com
or send us an email to kids @ scishow.com.
谢谢 我们下次见 这里是福特
Thanks and we’ll see you next time, here at the Fort.
