时差N小时 如何制作陨石坑?(上)

（单词翻译）

What makes science really fun is when you get to do things yourself, so today we’re going to be making moon craters¹.

科学真正有趣的时刻是当你亲身实践的时候，今天咱们来一起制作月球陨石坑吧！

They’re the roundish blast-marks left on the moon’s surface by ancient meteorites².

陨石坑是古代陨石撞击月球表面后留下圆形痕迹。

The moon’s surface is covered with literally³ billions of impact craters, and some of them are bigger than a fair-sized city on earth.

月球表面有数十亿的陨石坑，有的陨石坑甚至比地球上某个大城市还要大。

You can see the bigger ones just with the naked eye, and with a pair of binoculars⁴ you can make out many more.

通过肉眼，你只能看到月球表面较大的陨石坑，如果使用望远镜的话就能看到更多陨石坑。

So now let’s make some of our own. Take a wide, flat pan, such as the kind you’d bake cookies in.

现在，咱们来自己制作陨石坑吧。找一个宽的平底锅，类似于平时烘焙饼干的那种。

Take it outside, because this gets kind of messy! Poor flour or baking soda⁵ or sand across the bottom so it makes a thick, flat surface.

最好到户外做，因为实验现场会一团糟。将面粉、小苏打或沙子倒进锅底，形成一层厚实、平坦的表面。

That’s your undisturbed moon.

这就像未受到过撞击的月球表面。
