Slide1

Does Color Matter?

Miranda D. Adams

Bellwood-Antis High School

9

th

grade

Slide2

What color candle burns the longest?

I tested the candle colors; white for the lightest,

blue

,

orange

,

red

, and

purple

for the darkest…

Slide3

How could this help me?

Once you find out which candle color burns the slowest and or lasts the longest you could save some money!

Slide4

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

Slide5

Absorption

A perfect absorber reflects no radiant energy and appear black, or dark.

Dark candles will get warmer from the heat of the flame

Slide6

My Hypothesis

The white candle, the lightest, would burn the slowest when compared to the other four colors.

Slide7

First attempt

Burn candles until they went out.

Slide8

Better method

weighed

the candles on a mass scale.

Slide9

Procedure

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

Slide10

Experimental 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

Slide14

Temperature of burnt wax

Slide15

Conclusion

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!!

Slide16

Improvements

Burn the candles longer than 30

min

Use

a more sensitive scale

Slide17

Further REsearch

I

would get more colors of candles

Shape of the candles

Slide18

my materials I used…

5 candle-

lite

candles

White

Light blue

Orange

Red

Fisher EMD thermometer

An everyday lighter

Pie pan for burning
