    ____ You can learn about communications and the environment as well as math, physics and chemistry. For example, you can find out how people dig coal (煤) from the ground and use it to create energy. And in one room they even explain how X-rays let you see inside your body.

    The Launchpad on the third floor is the most popular room. ____ For example, if you want to fill a bag with sand, you have to control a kind of truck (卡车) on wheels and move it into the correct place. You can also find out how people travel into space and back again.
