candle+burning

**Title** burning scented candles

Problem Scenario
i am testing weather or not candle cents affect burning time of candles.

Broad Question
does scent addatives affect the burning time of candles?

Specific Question
What are the affects of scents on the burning time of candles?

Hypothesis
it is hypothesized that a candle with no scents will take longer to burn than ones with scents.

Independent Variable:
scent addatives

Dependent Variable:
burning time

Variables That Need To Be Controlled:
no scent candles

General Plan
In this experiment i am testing weather or not scents will affect the burning time of candles.

Experimental Design
(add the correct headings from the experimental design page before beginning)

Resources and Budget Table

 * Item || Number needed || Where I will get this || Cost ||
 * wax slab || 1 || my mom || free ||
 * candle maker || 1 || my mom || free ||
 * candle scent bottles || 2 ||  ||   ||
 * tea lites || 6 || wal mart || 1:00 ||

Detailed Procedure
1. get a slab of wax 2. draw 6 1 inch by 1 inch squares on it 3. cut those squares out 4. use the candle maker to meld the wax into a smal container 5. before the wax solidifys and 3 drops of selected scent into the wax and mix 6. repeat 1 more time then twise with the other scent 7 then repeat 2 more time but ad no scents 8.then burn them all one at a time and record how long it takes to burn half way down

Results
china rain had the lowest average out of all

Conclusion
The canldes with scents burned out quiker than the one with out.

Discussion
I was able to aswere my question with my experiment. After I averaged the times together china rain had the lowest average lavender followed and no scent had the highest average. The scent additives sped up the burning time up a lot. If some one was to measure the amount of drops went into the wax better than i did and used more trials of each scent would have had more accurate information.

Benefit to Community and/or Science
maybe if people want candles that burn longer they can get none scented candles.

Background Research
40 degrees Celsius melting

Abstract
My original thought was to find out if fragrance would impact the burn rate of a candle. To find this out, I chose 2 scents and also had a base w/out scent by which to compare the results. I used 2 of each to ensure accurate data; 2 china rain, 2 lavender and 2 w/ no scent. I melted wax in a tea lite put lavender in 2 china rain in another 2 and no scents were added to the last 2. Next I lit the tea lites and timed how long it took for them to burn. I took pics as they burned. After that I averaged the lavender times together and I did the same with china rain and no scent put them into a chart and made a graph out of that chart.
