    Welcome to the most friendly museum in London. In most museums, there is no shouting and no running, and you must not touch anything. {#blank#}1{#/blank#}It is noisy! People talk about what they can see and do here, and there are some very noisy machines as well. If you want answers to all your questions about science, this is the right place for you.

    {#blank#}2{#/blank#} 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. {#blank#}3{#/blank#} 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.

    Now, we arrive at the fourth and fifth floors. {#blank#}4{#/blank#} If you compare the medicine of the past with the medicine of today, you will feel very lucky next time you visit a doctor.

The Science Museum is interesting for people of all ages. You can always find something new and have a wonderful time there. The museum is free to enter. {#blank#}5{#/blank#} It is open daily from 10 a.m. to 6 p.m. So if you ever go to London, make sure you visit the Science Museum. It is my favorite museum in the whole world.
