What makes science really fun is when you get to do things yourself, so today we’re going to be making moon craters.
科學真正有趣的時刻是當你親身實踐的時候，今天咱們來一起制作月球隕石坑吧！
They’re the roundish blast-marks left on the moon’s surface by ancient meteorites.
隕石坑是古代隕石撞擊月球表面后留下圓形痕跡。
The moon’s surface is covered with literally billions of impact craters, and some of them are bigger than a fair-sized city on earth.
月球表面有數十億的隕石坑，有的隕石坑甚至比地球上某個大城市還要大。
You can see the bigger ones just with the naked eye, and with a pair of binoculars you can make out many more.
通過肉眼，你只能看到月球表面較大的隕石坑，如果使用望遠鏡的話就能看到更多隕石坑。
So now let’s make some of our own. Take a wide, flat pan, such as the kind you’d bake cookies in.
現在，咱們來自己制作隕石坑吧。找一個寬的平底鍋，類似于平時烘焙餅干的那種。
Take it outside, because this gets kind of messy! Poor flour or baking soda or sand across the bottom so it makes a thick, flat surface.
最好到戶外做，因為實驗現場會一團糟。將面粉、小蘇打或沙子倒進鍋底，形成一層厚實、平坦的表面。
That’s your undisturbed moon.
這就像未受到過撞擊的月球表面。
