Tape transcript:
Good evening. Welcome to our Science For Fun Program. This week, we’ve
received a lot of questions asking about life on the moon.
We’ve talked to some experts and this is what we’ve found out. There is no
Water or air on the moon. It is all silent because there is no air. Of course,
there will be no music, no sounds. There are no rivers and no lakes. At night,
it is very cold. The temperature goes down 1510 C below zero. But during
the day the temperature rises to 1000 C above zero.
There are great round holes on the moon. They look like big lakes. They are
called craters. There are more then 30,000 craters on the moon. There are
also high mountains. The highest mountains on the moon are about 26,000 feet
or 8,000 meters high.
And here is something very interesting to know: on the moon you weigh
one sixth of what you weigh on earth. If you weigh 50 kilos, on the moon
you will weigh only a little more than 8 kilos. You will be able to jump very high,
even higher than an Olympic Champion. You can take very long steps as well.
And … may be you want won’t sleep very well because one day on the moon
lasts for 2 weeks.
So, is there life on the moon? I’ll leave the questions for you to answer yourself.
