Life in space - level 1
British scientists send a balloon into the air. The balloon goes very high. It goes 27 kilometres (16.7 miles) above the ground.
When the balloon is back, the scientists look at it. They find something interesting. They find small organisms. These organisms are from the air.
The organisms are heavy. They cannot go into the air from the ground. The organisms come from space. This is a very important thing. It can change everything.
Difficult words: scientist (clever person who is an expert in something), balloon (big bag with air inside), organism (animal or plant or something that lives).
You can read the original story and watch the video in the Level 3 section.
