A Moment of Science
Firefighters expose themselves to dangerous chemicals and heat while they do their job.
Why doesn't the flame just continue to burn underneath the bell, no matter how flat you crush it? The answer is air.
You held a burning stick up to a non-burning stick. Why do you now have two burning sticks? The answer is in the nature of fire.
Robert Frost once wrote a poem about coming across an old woodpile in the forest. In describing it he refers to the “slow, smokeless burning of decay.” What a great line of poetry. Neat part about it is, it’s also technically correct. Decay is an extremely slow burning process. Or, you could say, fire is an extremely fast decaying process. In either case, what you have is the combination of carbon, oxygen, and hydrogen. Learn more on this Moment of Science.
A mysterious geological feature can be found on the slopes of Mount Rainier, a volcano in Washington state. Learn more on this Moment of Science.

What appears to be a dark cloud or haze to our eyes is actually made of millions of tiny particles–in this case, not of water, but of burnt matter. There are two kinds of smoke detectors: ionization alarms and photoelectric alarms.
Wildfires destroy enormous areas of forest every year. However, after forest fires, some plants manage to grow back at accelerated speeds.
