OK, that doesn't sound too bad. OK, ready for number two? Hmm, hmm.
好的，听起来还不错。好的，准备好听第二个了吗？是的。
Now this one is called ‘Unusual Measures of Lengths', and you basically use lots of paperclips.
现在这个叫做“不同寻常的长度测量”，基本上，你会用到很多曲别针。
The kids go around the class measuring things - you know, how long the desk is, and that sort of thing, um, and then they all compare their answers.
孩子们会在教室到处测量东西，比如课桌多长之类的。然后，他们会对比答案。
Er, and, basically, because not all paperclips are the same lengths, they should come up with some strangeanswers.
基本上，不是所有的曲别针都是一个长度，所以他们会得出一些奇怪的答案。
It's supposed to demonstrate the importance of having fixed units of measurement. Hmm, yes, that's not bad.
目的是证明用固定的单位进行测量很重要。
OK, now for number three you need rock salt or copper sulphate. Oh, I'm not sure about that!
好的，第三个实验需要你准备石盐或硫酸铜。这点我不敢确定。
Well, just put down the rock salt then, um, apart from that you only need a jar of water.
先记下石盐。除了这个你只需要一罐水。
Um, and basically you dissolve lots of salt into the water and watch the crystals form, so it basically teaches the kids about growing crystals.
大体上，你在水中溶解很多盐，看着它凝结成晶体状，这是教孩子晶体的形成。
Yeah. I suppose it would be nice to grow something. Hmm, let's move on and have a look at number four.
是的，我想生成一些东西是好事。让我们看看第四个实验。
