Welcome to space camp.

Would you like to enjoy an astronaut’s experience (体验) without leaving Earth? You can do it at a space camp.

Astronauts need to do simulation (模拟) activities before they do on a space travel.

At space camp, you will do them, too. You will begin by watching demonstrations (示范). You will play games and do experiments (实验) with other campers. After that, you will be ready to try out the same simulate activities as astronauts do.

At space camp, you practice doing things in zero gravity (重力). At some camps you can use a 1/6th gravity chair. In the 1/6th gravity chair, you will feel like you are walking on the moon. In a weightlessness simulator, you will float and walk as you would float and walk in space. These are some of the simulators you can use at camp.

At space camp, you will learn to eat as you would in space. Food floats in the air. Sometimes you have to catch it to eat it. Sometimes you squeeze (挤) food out of a tube (管), right into your mouth!

Space camps let you try many different activities. Some camps let you build and launch (发射) a small rocket. At other camps, you can build and operate a robot. You may learn how to stay alive or do experiments. All these activities let you feel what it is like to be an astronaut in space.

Rain forests are located（位于）around the equator（赤道）. It is very warm around the equator. The rain forest stays at 75° F—80° F all year round. The rain forests are wet! Very wet! In fact, rain forests can get between 160 and 300 inches of rain each year. Because the rain forests are always warm and wet, plants grow all year long. The rain forest is home to more plants and trees than any other location in the world!

Count on Me, and I’ll Count on You

In the rain forest, plants, animals, and people need one another to live. Almost everything that falls to the forest floor is reused. When plants and animals die, they break down and feed living plants. In turn, those plants give food and shelter（庇护所）to people, animals, and other plants. Water in the rain forest is also reused. It evaporates（蒸发）, forms clouds, and then falls back to Earth as rain.

Gifts from the Rain Forest

The rain forests may seem very far away, but you use something from them every day! For example, do you like chocolate? How about chewing gum?

Thank the rain forests! Rain forests are a huge source（来源）of food. Fruits such as mangoes and bananas come from the rain forests. So do many nuts, spices, and vegetables. Many medicines also come from the rain forests. One-fifth of the world’s fresh water is in the Amazon rain forest. The rain forests affect（影响）rainfall, which in turn affects climate（气候）around the world.
