Two of the Gases in the Atmosphere
Posted in Scientific Saturday
I haven't done Scientific Saturday in a long time! Partly because I didn't know what to do it on, and partly because I had forgotten about it. But I'm going to start back into it, if you will allow me. Especially now that we have been back in school for over two months now! 
Oxygen is a gas that is essential to life here on earth. You could only exist for about three minutes without oxygen. People and animals use oxygen and give off carbon dioxide, while plants use carbon dioxide and give off oxygen. God has designed the system perfectly! Since oxygen is so important, you may wonder "Why?" when I tell you that only about 21% of the atmosphere is composed of oxygen! God makes no mistakes, remember? God sure knew what he was doing not to make 100% of the atmosphere oxygen.
Besides the fact that plants could not survive, we would also have a huge problem with fires if there was that much oxygen in the air. We would not be able to control fire. In some ways, fire is a good thing. You use fire everyday! We take it for granted, but we use it! But fire is also very dangerous. Fire can seriously injure and/or kill. If the atmosphere was 100% oxygen, heated iron would burn strongly, as well! I have a feeling that we would not live very long if there was that much oxygen in the air!
God also knew what he was doing when he made almost 80% of the atmosphere nitrogen. Nitrogen is inert, which means that it will not quickly combine with other gases. Having so much nitrogen in the air "waters down" the oxygen in the air. As I mentioned before, if we had pure oxygen, the earth would burst into flames! The nitrogen keeps that from happening.

I'm very impressed, whether or not you post Scientific Saturdays regularly! I'm awful at science...maybe even worse than Algebra.... :-)
I awarded you the Nice Matters award, even though you don't post them on your blog. I simply couldn't resist--you post about so many nice matters! :-D

It drives me nuts! I don't spend a lot of time on blogs like that eather.

That is a funny video. very cool. Someone has alot of time on their hands. It's a TV show in Japan geared toward 2-6 year olds. They kept saying switch, or suchi. You can hear it in the phrase. The show is called Pitagora Suichi. Not sure what Pitagora is. I heard 12 in there somewhere :D But thats it. But yeah It's a very popular television show.
