Sometimes, a power shortage can occur in your neighborhood. In my book, whenever a shortage does occur, my family and I resort to grabbing candles from a cabinet in the back and lighting it in order to receive at least some light. However, something interesting oddly compelled me to research. This thought came to mind because we usually used the plain white candles anyone could purchase at the dollar store. Then, it hit me. We could also use color dye candles not only for their scent, but maybe they could serve a better purpose and provide light for a longer amount of time. Hence, I decided I wanted to test this theory.
To continue, I want to test which of the different types of candles will last longer in terms of the flame, or the light.

In this case, my independent variable is the candle because the color does not change throughout the experiment. Furthermore, my experiment will not contain an approximate time limit. For an example, the candles will not have to start burning in under three or four minutes. In this amount of time, the flame is slowly but surely consuming the wick and the fuel source, or the wax. However, the candles will be timed using a device that could record time. Most likely, if one candle finishes before another, this is a point where one candle was inevitably better than the other because it lasted longer. However, a possibility of both candles ending at about the same time is still likely. Both candles will consume their fuel before the time ends as well. Moreover, each of the times, as to be expected, might not be differentiate each time in the trials. To explain, because their brands and colors won’t likely change, their times should line up equally during tests. Although the chemicals in a colored candle are added for scent, they may vary in how big or thick the candle is. This won't likely affect its melting time, because the chemicals are not added for duration. However, only the size of the candle could affect the rate of which the candle burns but the candles will be identical in each trial. This varies in size though because not only is the height being measured, but also the width or circumference must be identical. To summarize, in my experiment, my white candle will be the independent
Colored fire is a common pyrotechnic effect used in movies, fireworks and by fire performers all over the world. Generally the color of the flame may be red, orange, yellow, or white, and is controlled by blackbody radiation from soot and steam. When additional chemicals are added to the fire, the flame would appear a different color according to the other chemicals. Flame coloring is also a good way to show how chemicals change when heated and how they change the matter around them.
For new or retrofit construction, every choice can lead to energy savings; energy that is derived primarily from fossil fuels. The typical household LED replacement for a 60w light lasts about 50,000 hours. Pretending that an incandescent could also last that long, it would consume about 3,000 kilowatt-hours (kWh) of energy whereas the LE...
Experiment #2: The purpose of this experiment is to test which colors work best and float while under a different light source.
Our 100% all natural beeswax candle in Frosted Square Glass Candles burn longer and cleaner than all traditional wax glass candles. Our lovely candles are completely non-toxic, non-allergenic and non-carcinogenic. With its healthful negative ions and warm, halo glows they act like indoor air purifiers. Our candles have been proven to be beneficial for people who have allergies, environmental sensitivities or just too much stress in their life. 100% natural beeswax candles are the cleanest burning candles that you will ever burn. Rest easy knowing that this sophisticated candle is biodegradable and free of synthetics. Pure beeswax candles have many redeeming properties it is a pure, unadulterated fuel, has a
Variables --------- During the experiments, the water will be heated using different spirit burners containing different alcohols. I will be able to change different parts of the experiment. These are the. Volume of water heated:
Limitations of Experimental Design- My experimental design helped answer the original question adequately. Since the syringes were small, wrapping them in colored film was relatively simple and took little time to do. Using colored film was also more effective than using colored bulbs, the original plan. Colored bulbs would have ...
About 10,000 diverse species of pigments and dyes are used in industries, which show that an annual use of almost 7×105 tonnes in world. Dyes are intractable and toxic materials, they oppose biological breakdown (Souza et al., 2007).
My study is based on the communication techniques used by Yankee Candle CEO Harlan Kent and his employees as he goes undercover at four different locations to gain a better understanding of his company and how operations take place when he is not around.
There are more than 400 commercial, religious and institutional manufacturers of candles in the United States, in addition to scores of small craft producers for local, non-commercial use.
The measurements [Mass of alcohol burned (g), Temperature increase (oc)] will tell me what mass of alcohol is used during combustion to cause the temperature increase of 20oc in the water, I can then work out the energy released per mole and compare these values and see which has the highest enthalpy of combustion. I will need to repeat my experiment a number of times and take an average so I am sure of an accurate result.
Independent variables: The temperature of hcl gas will be decreased and increased throughout the experiment.
I picked the science experiment elephant toothpaste this year, because it seems interesting and fun. It is also a way to test if the removal of oxygen in these experiments will actually work. I have four different experiments. Two out of the four experiments I am testing, is to see if there is a different reaction time and size between yeast and potassium permanganate and the percentage of the hydrogen peroxide. My third and fourth are tests of elephant toothpaste is to see if adding cornstarch has a color reaction to the potassium iodide to make it look like it is “glowing”, or if the yeast and fluorescent dye will make it look “glowing”. I think the elephant toothpaste that uses 50% hydrogen peroxide and potassium permanganate will have the
The design for this study will be a simple between subject experiment consisting of one experimental group and one control group. The independent variable will be warm colors. The dependent variable will be mood. The main goal is to determine if the independent variable will influence or cause difference in the specified dependent variable. The experiment group will spend 60 minutes in a warm paint color room and their mood will be measured. The control group will spend 60 minutes in a neutral paint color room and their mood will be measured.
...cal profession makes use of color in certain treatments. For instance, premature babies with jaundice are cured by a chemical reaction triggered by exposure to blue light for several days. The relation between blue light and jaundice is beginning to be well understood scientifically.
Ultimately when conducting this experiment I need to look at how to determine chemical change and how to measure
