Hi children,
Here are some "airy" questions posed by some of you which I thought are quite intriguing. Why don't you have a look and see if you can help some of your classmates out?
Prying into the affairs of the universe, Gareth asked, "Do other planets in the solar system have air?"
Lee Xian inquired, "If the whole full is full of air, why are we still able to fit into this world?"
The following is a popular question amongst some of you - "Why can't we see air?"
Tara and Rachel, being concerned about the survival of the human race, would like to know if it is possible to run out of air on this planet.
Another popular question - How many types of gases are there in the world?
Last but not least, "Why does the human need air to live?" the ever inquisitive Cher Huey demands to know.
These are just some of the many interesting questions posed by you. If you have a worthwhile comment or two to make, you are welcome to share. Looking forward to a lively discussion!
I remain,
Mr Tan Mun Sing

to gareth's question i say there might be as i read books and wacthed documentary and they have found some planets with air out of this solar system.
to cher huey's question the awnser is we need air so that we have enegy that will be sent to the brain or else you will die.
Hi Vincent,
I totally agree with you with regards to Cher Huey's question. Air, specifically oxygen is needed to be converted into energy that will be sent to different parts of the body, not only the brain!
Well, on Gareth's question, all I can say that is for life to exist out in the Universe, two things are essential. That is oxygen and water.
Thanks!
