My rock is really dark brown.[qh]
我的石头是深棕色的。[qh]
Maybe because it was burning in space.[qh]
也许是因为它在太空中燃烧过的原因。[qh]
Alright so far so good.[qh]
好的，到目前为止一切都很好。[qh]
But let's look at shape next.[qh]
但接下来让我们来看看形状。[qh]
Meteorites usually aren't perfect circles or squares, instead they have irregular or unusual shapes like they might look really lumpy.[qh]
陨石通常不是完美的圆形或正方形，相反，它们有不规则或不寻常的形状，看起来可能真的很粗糙。[qh]
But an important thing is they also feel smooth and don't have any holes in them.[qh]
但重要的是，它们也摸起来很光滑，没有任何孔洞。[qh]
Well, this rock is shaped like a meteorite and it doesn't have any holes in it.[qh]
嗯，这块岩石的形状像陨石，上面没有任何孔洞。[qh]
But it's not that smooth.[qh]
但这并不是那么光滑。[qh]
All right, let's take a look at the next test then.[qh]
好了，那我们来看下一个测试。[qh]
This is a test to see how dense the rock is.[qh]
这是一项测试，看看岩石的密度。[qh]
We say an object is really dense when it's pretty small, but also really heavy for its size.[qh]
当一个物体很小的时候，我们说它密度很大，但相对于它的大小来说，它也很重。。[qh]
If you pick up a small object and it's way heavier than it looks.[qh]
如果你拿起一个小物体，它比看起来要重得多。[qh]
That's probably a good sign that it's dense.[qh]
这可能是一个很好的迹象，表明它是密集的。[qh]
Meteorites are really dense.[qh]
陨石密度很大。[qh]
So they have a lot of stuff packed into a small space.[qh]
所以他们在一个很小的空间里放了很多东西。[qh]
This makes them a lot heavier than earth rocks that are the same size.[qh]
这使得它们比同等大小的地球岩石要重得多。[qh]
I actually brought some rocks in from the garden earlier this morning so I could learn more about them.[qh]
事实上，今天早上早些时候，我从花园里带了一些石头进来，这样我就可以更多地了解它们。[qh]
So, we can compare how heavy they feel.[qh]
因此，我们可以感受一下他们重量的对比。[qh]
So, how heavy does it feel compared to my rock.[qh]
那么，与我的石头相比，你感觉地球石头有多重。[qh]
You know your rock does feel pretty heavy.[qh]
你知道，你的石头确实感觉很重。[qh]
I think it's pretty dense.[qh]
我觉得它的密度很大。[qh]
Wow, does that mean it's a meteorite？[qh]
哇，这是不是意味着它是一块陨石？ [qh]
Let's do one last test just to be sure we're gonna test if your rock is magnetic do you remember what meteorites are made of, Sam.[qh]
让我们做最后一次测试，以确定我们要测试你的岩石是否具有磁性。你还记得陨石是什么组成的吗，山姆。[qh]
Totally they're made of crystals or metal.[qh]
它们完全是由水晶或金属制成的。[qh]
That's right Most meteorites have the metal iron in them.[qh]
没错，大多数陨石都含有金属铁。[qh]
And iron sticks to magnets when something sticks to a magnet we call it magnetic.[qh]
当有东西粘在磁铁上时，铁会粘在磁铁上，我们称之为磁性。[qh]
So, if this rock is a meteorite then the iron in it should make this magnet stick to the rock.[qh]
因此，如果这块岩石是陨石，那么其中的铁应该会使这块磁铁粘在岩石上。[qh]
Let's try it.[qh]
让我们试一试吧。[qh]
Look at that![qh]
看那儿![qh]
Wow, It's magnetic.[qh]
哇，它很有磁性。[qh]
So, let's see what we Learned.[qh]
那么，让我们看看我们学到了什么。[qh]
This is an unusual rock and it's the right color to be a meteorite.[qh]
这是一块不同寻常的岩石，它的颜色符合陨石。[qh]
It also has a good irregular shape like a meteorite.[qh]
它的形状也像陨石一样不规则。[qh]
It is a little rough but it also doesn't have holes.[qh]
它有点粗糙，但也没有洞。[qh]
It's also pretty dense and is magnetic.[qh]
它的密度也很高，而且很有磁性。[qh]
What do you think, Sam?[qh]
你觉得呢，山姆？[qh]
That sounds like a meteorite to me.[qh]
对我来说这听起来像陨石。[qh]
You know, I think you're right.[qh]
你知道吗，我想你是对的。[qh]
Even if it's not super smooth,it checks all our other boxes.[qh]
即使它不是超级光滑，他也符合我们其他的选项。[qh]
So wow congrats Sam.[qh]
所以，哇，祝贺你，山姆。[qh]
You found a space rock.[qh]
你发现了一块太空岩石。[qh]
Well,Thanks, Mr Brown.[qh]
嗯，谢谢你，布朗先生。[qh]
I had a lot of fun learning about my rock too.[qh]
学习关于我的石头的知识我也很开心。[qh]
Meteorite testing with you is really cool.[qh]
和你一起做陨石测试真的很酷。[qh]
And I Learned a lot actually.[qh]
事实上，我学到了很多。[qh]
Now, I want to go see if there are any other meteorites outside.[qh]
现在，我想去看看外面有没有其他陨石。[qh]
I'll catch you later.[qh]
我待会再来找你。[qh]
I'm glad you enjoyed it.[qh]
我很高兴你喜欢它。[qh]
Bye Sam.[qh]
再见，山姆。[qh]
bye . [qh]
再见。[qh]
Sam，the bat， loves space.[qh]
蝙蝠山姆喜欢太空。[qh]
And I happen to know that he loves spaghetti.[qh]
我碰巧知道他喜欢意大利面。[qh]
So, what if we made him a spaghetti and meatball solar system with different meatballs for all the planets.[qh]
那么，如果我们给他将意大利面和肉丸做成太阳系的样子，用肉丸做所有的行星怎么样？[qh]
Right, Sam is a bat and they love eating bugs.[qh]
对，山姆是蝙蝠，它们喜欢吃虫子。[qh]
So, I'll need to make mosquito meatballs.[qh]
所以，我需要做蚊子肉丸。[qh]
I'll need to find a recipe for that.[qh]
我需要找出那道菜的配方。[qh]
Okay, next up is our neighbor Mr Brown.[qh]
好的，下一位是我们的邻居布朗先生。[qh]
Oh, hi everyone![qh]
哦，大家好！[qh]
Squeaks is supposed to meet me here in the lab, but he's not here yet.[qh]
吱吱应该在实验室和我见面，但他还没到。[qh]
I wonder what's taking him so long.[qh]
我想知道他怎么花了这么长时间。[qh]
I'm super excited to see him because he promised he'd show me his new magnet.[qh]
我超级想见他，因为他答应给我看他的新磁铁。[qh]
Oh, there you are, squeaks.[qh]
哦，你来了，吱吱。[qh]
Is everything okay?[qh]
一切都还好吧？[qh]
Oh,I see.[qh]
哦，我明白了。[qh]
Squeaks was trying out his new magnet by the river.[qh]
吱吱正在河边试探他的新磁铁。[qh]
And the path there is really long and windy, so it took him a while to find his way back to the fort.[qh]
而且那里的路真的很长，风很大，所以他花了一段时间才找到回到堡垒的路。[qh]
Hmm The river is directly south of here.[qh]
嗯，这条河就在这里的正南方。[qh]
If only you had had a compass, then you could have taken a shortcut.[qh]
如果你有一个指南针，你就可以走捷径了。[qh]
A compass it's a tool that can tell you what direction you're going.[qh]
指南针这是一种工具，它可以告诉你你要去的方向。[qh]
And if you know what direction you're going, you can find your way around without getting lost.[qh]
如果你知道你要去的方向，你就可以在不迷路的情况下找到你的路。[qh]
People have been using compasses for thousands of years to explore the world.[qh]
几千年来，人们一直使用指南针来探索世界。[qh]
They can be big or small fancier plane, but they have an important thing in common.[qh]
它们可以是大的或小的平面，但有一个重要的共同点。[qh]
They have some kind of arrow or needle that points north.[qh]
他们有某种指向北方的箭头或针。[qh]
So, if we had a compass right now its needle would point this way because that's north.[qh]
所以，如果我们现在有一个指南针，它的指针会指向这个方向，因为那里是北方。[qh]
In fact we can use your magnet to make your own compass right here at the fort.[qh]
事实上，我们可以在堡垒用你的磁铁来制作你自己的指南针。[qh]
