Does wax color affect the
burning time of a candle?
9-2 Project 1
Purpose
• The Purpose of my project is to find out if
the color in wax affects the amount of
time a candle burns.
Hypothesis
• I think the white candle will burn the
quickest because its all wax and does not
contain any dyes, and the candles with
dyes will take longer because they have
more contents to burn.
Materials
• The Materials I used in my project are:
- 4 candles, 3 colored and 1 white.
- Timer.
- Measuring Tape
- Black Marker
- 4 Candle Holders
- Lighter.
Method
- First I took the 4 candles and placed them in candle
holders.
- I then took a black marker and marked them 3 inches
from the top of the candle.
- Next I placed the candles on a hard, flat surface 4 inches
apart from each other.
- Then I lit them and waited for them to burn down to 3
inches, then recorded the results.
- I repeated my project 2 more times to be sure the
results I got were accurate.
Variables
• Manipulated: the color of the candle.
• Responding: the length of time it took the
candles to burn.
• Controlled: the height and width of the
candles, the brand of the candles, and the
number of inches I let them burn.

Conclusion
• In conclusion I found that the color of wax
does affect the burning time of candle
according to my results. Also the
hypothesis I stated was correct and the
white candle did burn the fastest.
Sources of Error.

3.
Some sources of error are:
When I lit the candles I lit them one after the other
instead of all at once this may have affected my results
because one candle may have gotten a longer burning
time then the other.
I also set my project up in a kitchen area and people
did walk past my project several times and could have
given one or more candles oxygen or dimmed the
flame on them.
When I measured and marked 3 inches on the candles
I could have been off by 2-3 millimeters because it
was hard to mark on the candle.
Ways to Improve.
•
Some ways I could have improved my
project are:
1. When I lit the candles I should have lit
them all at once instead of one after the
other.
2. I could have compared different brands
of candles to see if one brand would be
better then another.
