Slide2What color candle burns the longest?
I tested the candle colors; white for the lightest,
blue
,
orange
,
red
, and
purple
for the darkest…
Slide3How could this help me?
Once you find out which candle color burns the slowest and or lasts the longest you could save some money!
Slide4reflection
Light-colored objects reflect more light and heat, compared to dark-colored objects
Light colored candle won’t get as warm from the heat of the flame
Slide5Absorption
A perfect absorber reflects no radiant energy and appear black, or dark.
Dark candles will get warmer from the heat of the flame
Slide6My Hypothesis
The white candle, the lightest, would burn the slowest when compared to the other four colors.
Slide7First attempt
Burn candles until they went out.
Slide8Better method
weighed
the candles on a mass scale.
Slide9Procedure
Buy 24 candles, 6 candles of each colorThen lighted the candles in the following order; orange, white, purple, red, and blue. burned all five candles for 30 minutesAfter the 30 minutes I measured:temperature of the melted waxthe final mass
Slide10Experimental Design
Experimental variable
Colors of the candles
Experimental groups
different colored candles
White,
blue
,
orange
,
red
, and
purple
Slide11
Controls on candlesheight = 5 ±0.1 cm.diameter = 3.8 ±0.1 cmwick length = 1.1 ±0.1 cminitial mass = 46.6 ±0.1 gcandle's brand
Slide12
Controls on Environment
Room temperature was 22.2
° ±
0.1 C
Distance between them
No drafts
Slide13
Average Mass Lost
Slide14Temperature of burnt wax
Slide15Conclusion
I found out that the fastest burning candle was not the white one.
Therefore, I reject my hypothesis which stated that the lightest, the white, would burn the fastest.
So according to my experiment color does matter!!
Slide16Improvements
Burn the candles longer than 30
min
Use
a more sensitive scale
Slide17Further REsearch
I
would get more colors of candles
Shape of the candles
Slide18my materials I used…
5 candle-
