1. DOES COLOR MATTER?DOES COLOR MATTER?DOES COLOR MATTER?DOES COLOR MATTER? Miranda D. Adams Bellwood-Antis High School 9 th grade

2. W HAT COLOR CANDLE BURNS THE LONGEST ? I tested the candle colors; white for the lightest, blue, orange, red, and purple for the darkest…

3. H OW COULD THIS HELP ME ? Once you find out which candle color burns the slowest and or lasts the longest you could save some money!

4. REFLECTION 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

5. A BSORPTION A perfect absorber reflects no radiant energy and appear black, or dark. Dark candles will get warmer from the heat of the flame

6. M Y H YPOTHESIS The white candle, the lightest, would burn the slowest when compared to the other four colors.

7. F IRST ATTEMPT Burn candles until they went out.

8. B ETTER METHOD weighed the candles on a mass scale.

9. P ROCEDURE Buy 24 candles, 6 candles of each color Then lighted the candles in the following order; orange, white, purple, red, and blue. burned all five candles for 30 minutes After the 30 minutes I measured: temperature of the melted wax the final mass

10. E XPERIMENTAL D ESIGN Experimental variable Colors of the candles Experimental groups different colored candles White, blue, orange, red, and purple

11. Controls on candles height = 5 ±0.1 cm. diameter = 3.8 ±0.1 cm wick length = 1.1 ±0.1 cm initial mass = 46.6 ±0.1 g candle's brand

12. Controls on Environment Room temperature was 22.2° ± 0.1 C Distance between them No drafts

14. T EMPERATURE OF BURNT WAX

15. C ONCLUSION 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!!

16. I MPROVEMENTS Burn the candles longer than 30 min Use a more sensitive scale

17. F URTHER RE SEARCH I would get more colors of candles Shape of the candles

18. MY MATERIALS I USED … 5 candle-lite candles White Light blue Orange Red Purple Fisher EMD thermometer An everyday lighter Pie pan for burning Timer (clock) Ruler
