Hi, everyone! Squeaks and I have a problem. We were about to start cooking lunch, but then we saw that it's the perfect day to be outdoors.
嗨，大家好！我和吱吱有个问题。我们正要开始做午饭，但后来我们发现现在是户外活动的最佳时机。
We're trying to figure out how we can cook and play outside at the same time… I know! We can build a solar oven!
我们在想怎么能一边做饭一边在外面玩……我知道了！咱们可以造一个太阳能烤箱！
Solar ovens are a lot like kitchen ovens. They're basically boxes that heat up inside, and that are great at keeping the heat trapped inside of the box.
太阳能烤箱和厨房烤箱很像，它们基本上都是在里面加热的盒子，然后能够很好地将热量困在盒子里。
If you put food inside of the oven, the heat cooks the food.
如果你把食物放在烤箱里，热量会把食物烤熟。
What makes it a solar oven?
太阳能烤箱的热量来自哪里呢？
Well, kitchen ovens use electricity or burn gas to make themselves hot.
嗯，厨房烤炉用电或烧煤气加热。
A solar oven uses solar energy — or energy from the Sun!
太阳能烤箱使用太阳能——或者说是来自太阳的能量！
When light from the Sun shines into a solar oven, it heats up the inside of the box.
当太阳光照射到太阳能烤箱时，它会加热盒子的内部。
This means they're perfect for cooking outside!
这意味着太阳能烤箱非常适合在户外作业！
You can make a solar oven using materials you might already have.
我们可以用现有的材料制作太阳能烤箱。
Hey, Squeaks — will you help me design our oven?
嘿，吱吱——你能帮我一起设计咱们的烤箱吗？
Awesome! I've brought some materials for us.
太棒了！我给咱们带了一些材料。
First, we have a pizza box to use as the main box of the oven, and I have some tin foil, too.
首先，我们有一个比萨饼盒用作烤箱的主盒，我还有一些锡纸。
Tin foil is a great insulator, or something that's great at trapping heat.
锡箔是一种很好的绝缘体，或者说它很擅长蓄热。
So, it can help us to keep the heat inside the box.
所以，它可以帮助我们把热量存贮在盒子里。
I'll cover the inside of the box with tin foil, and tape it down.
我要用锡纸把盒子内侧盖住，然后用胶带把锡纸粘在里面。
Hm, now, we have our first design challenge.
现在，我们遇到了我们的第一个设计挑战。
We need sunlight to get into our box, but if we open the box, all the heat will get out.
我们需要阳光进入盒子，但如果我们打开盒子，所有的热量就会散出来。
Is there something that we could change about our box to get sunlight in, while still keeping the box closed?
我们能否既改变盒子让阳光照进来，同时又能让盒子保持封闭状态？
A window… that could work! It will be like how windows can let sunlight into a building, even if they're closed.
一扇窗户，会有用的！就像窗户即便是关着的，但阳光还是可以进入屋内。
I'll make a flap, so we can open and close our "window."
我要剪一个翻板，这样我们就可以打开或关闭我们的“窗户”。
And kids, make sure that when you're cutting your flap that an adult is around to help you.
孩子们，你在剪翻板的时候一定要有大人在旁边帮助你。
Normally, windows use glass to separate the inside and outside.
通常情况下，窗户要使用玻璃来分隔内外。
We want something clear like glass, that will let sunlight in, but that doesn't break as easily.
我们想要像玻璃这样透明的东西，能让阳光照进来，但又不会那么容易破碎。
What do you think we should use?
你觉得我们应该用什么呢？
Plastic wrap is a great idea! We can cover the window in plastic wrap, and tape it around the edges to keep the heat inside the oven.
用塑料袋包装是个好主意！我们可以用保鲜膜把窗户盖上，并把它贴在边缘，这样就可以保持烤箱内的热量了。
Now sunlight can get into the oven, and heat up our food!
现在阳光可以进入烤箱加热我们的食物了！
Uh-oh… I think there's another problem with our design.
啊哦，我想我们的设计还有一个问题。
The only sunlight that can get into our box is the light that shines straight into our window. And that's not enough.
唯一能照进盒子里的阳光是直射进窗户的光，这还不够。
So, here's our second design challenge! How can we get more light into our solar oven?
所以，这是我们的第二个设计挑战：怎样才能让更多的阳光进入我们的太阳能烤箱呢？
I've got an idea! Did you know light can bounce?
我有个主意！你知道光可以反射吗？
If you shine a flashlight in a mirror, the light will bounce off it and back at you. And it does this on more than just mirrors!
如果你用手电筒照镜子，光线会反射到镜子上，反射到你身上，而且不仅仅有镜子可以这样。
Anything with a shiny surface can make light bounce, or reflect.
任何表面光泽的东西都能使光线反射。
So if we want to reflect some sunlight into our solar oven, we need something shiny!
所以，如果我们想将一些阳光反射进我们的太阳烤箱里，我们需要一些亮亮的东西！
The tin foil! The tin foil is very shiny! We can try using that to reflect the sunlight into the box. Thanks Squeaks!
锡箔！锡纸很亮！我们可以试着用它把阳光反射进盒子里。谢谢吱吱！
I'll tape some tin foil to the section of lid we cut out to make our window.
我要在我们切下来做窗户的翻板上粘上一些锡纸。
If we angle this just right, the sunlight aimed at the tin foil should bounce off of it and shoot straight into our oven!
如果我们的角度合适，对准锡箔的阳光应该会从锡箔上反弹，直接射进我们的烤箱！
We can use this pencil to hold that lid at the right angle.
我们可以用这支铅笔把翻板固定在合适的角度。
Next, we'll put the food on a plate inside to cook. That leaves us with our third and final design challenge: Which color plate should we use?
接下来，我们把食物放在里面的盘子里进行烹饪。这就给我们带来了第三个也是最后一个设计挑战：我们应该使用哪种盘子？
We have a bunch of paper plates from Sam the Bat's birthday party. We have a white plates and black plates.
我们有一堆蝙蝠山姆生日派对上的纸盘子，有白色盘子和黑色盘子。
I'm glad you asked. The colors matter because dark colors heat up in the sunlight faster than lighter colors.
问得好，颜色很重要，因为深色比浅色在阳光下更易升温。
You might have noticed this if you've ever worn a dark shirt outside in the summer!
如果你之前有在夏天穿黑衬衫出门，那么你可能知道这一点！
We probably want a dark-colored plate to help us heat up our food then, don't we?
我们可能需要一个深色的盘子来加热我们的食物，对吧？
I agree, let's use the black plate. That one is darkest.
我同意，我们用黑色的盘子吧。这个盘子是最黑的。
It looks like we're ready to test out our solar oven! How about some pizza bagels?
看来我们准备好测试我们的太阳能烤箱了！整点儿披萨百吉饼怎么样？
We're going to head outside to test our solar oven. Depending on what happens, we might make changes to our design.
我们要出去测试一下我们的太阳能烤箱。我们可能会根据情况对设计进行某些更改。
Maybe we'll paint the entire inside of the oven black, or find a shiny mirror to help reflect more sunlight into the window.
我们把烤箱的内部全部涂成黑色怎么样，或者找个闪亮的镜子帮助反射更多的阳光到窗户里。
What ideas do you have to make our oven better?
你有什么好主意让我们的烤箱变得更好呢？
Ask a grown-up to help you to build your own design, and test it out!
可以找一个大人帮你设计并进行测试！
