Do candles burn more slowly if placed in the refrigerator?
Hypothesis
Variables
Dependent variable- The candle will burn more slowly in the refrigerator
Controlled variable- Same candle, same refrigerator, same lighter, same amount of coolness being released in the refrigerator, same area where candle is being placed.
Materials
My procedures. (What I did)
Get candle
Get a lighter
Go to refrigerator
Light candle
- Place the lit candle in refrigerator
- Watch how long the candle burns for
My data (What happened)
Trials
How long the candle burned in the refrigerator.
Qualitative Data
1.
47 Seconds
The flame was normal but it kept getting smaller and smaller and went out.
2.
48 Seconds
Same as last time the flame got really small and went out.
3.
46 seconds
The same thing happened again and it went out.
4.
53 Seconds
This time I let the candle burn for a minute then placed it in the refrigerator.
Mean
48.5
My conclusion
If a candle was placed into a refrigerator then the flame will get smaller and go out. It got kind of hard to see the candle but I put it in one of those see through refrigerator cabinets and that is how I could test my experiment.
