Question
experiment (on Scientific Method). (Length of report should fit in 1-2 pages max)
Follow the instructions and submit it:
1) observe how a lighted candle can sustain its flame. To do this, choose a safe place -far from combustible materials- and light a small candle, observe it for a few minutes and write a brief description of what you observe. Take a picture of the lighted candle.
2) Type a short report using your own words for the following sections (in the correct order):
Purpose (i.e. what do you want to find out about the lighted candle),
Data and observations (keep this brief and interesting). Paste a copy of the picture you took of the candle.
Conclusion: Did you note any changes in the candle? What allowed the candle to burn? Why did it continue burning for the duration of your observations?
Explanation / Answer
The purpose is to determine how it is the flame formed in the candle and why it stays turned on during for observation, this is, what feed the flame to continue burning.
Data:
Temperature: as the hand is nearer the flame temperature increases. So the flame release heat
Color of the flame : You have to describe the colors you observe. The parts of the flame blue? yellow? sizzling?

color of the light of the candle: describe what you observe at the surround of it.
Odor: Describe the odor of the candle with your own words.
form of the candle : does it changes over time?
Conclusion; resume which were the major changes observed in the candle during the observation time
What allowed the candle to burn? the combustion reaction. The paraffin is an hydrocarbon that act as combustible while the oxygen in the enviroment is the oxyder. This reaction goes with light and heat.
Why did it continue burning for the duration of your observations? it continues because there is a continuos flow of Oxygen and paraffin to burn. So while none of them is over the reaction will continue over time.
