Green Candle Lab

The experiment can also be done to compare the burn rate of different colored candles.

If the difference between the recorded times are more than 10%, add a third trial. Repeat these steps with each size beaker. Calculate the average time for each beaker and record the data. The next step of the lab exercise is determining the exact volume of the beakers used in the burn time experiment. Fill a beaker to the top with water. Carefully pour the water from the beaker into a graduated cylinder. Reading the meniscus, record the exact volume into a data sheet. Repeat this step with each size beaker until all volumes are recorded into the data sheet. The final process of the Graphing and Estimating lab is plotting the recorded data onto a graph. Using the data recorded for burn time, in seconds, place the data on the vertical axis. Use the horizontal axis for the volume in milliliters. With the data points plotted determine whether a straight line or a simple curve will best represent the data. Now, obtain a jar and determine the volume. Fill the jar to the top with water. Carefully pour the water into a graduated cylinder. Precisely record the data. Using the plotted data on the graph and the simple curve or straight line to predict how long it would take for the flame to burn out on the candle if it was covered with the jar that was just measured.

The atom of an element has electrons that are found around the nucleus in regions known as orbitals. When energy is absorbed by the electrons of an atom they begin to jump to higher energy levels. When this happens the electrons are in an excited state. However when the electrons begin to release the energy and drop in energy levels they emit electromagnetic radiation. If the radiation that is emitted falls between 400 to 700 nanometers then the electrons emit photons which we can see as visible light.

The candles normally used are Biosun ear candles, which are made by hand today using the traditional recipe incorporating

Millhouse Candles has an article on their website with a timeline of candle history. “A Short History of Candles” outlines this history from 3000 BC to present. This outline is broken up into four periods, 3000 to 1 BC, 1 BC to 1500 AD, 1500 AD to 1799 AD, and 1800 AD to present. Each of these time periods contain facts about the cultures that were making candles, the materials used for the candles within the periods and a technological advancement for that time.

Purpose To determine the effect of beaker size on the time a candle will burn. [How could the size of a beaker affect the time length a candle can burn, if the beaker was placed over the candle?] Background Information Independent Variable:

For this experiment it takes about two and a half hours to complete. Do this experiment in an open space where nothing could catch on fire as the experiment is being done. Make sure you are watching this experiment at all times and also make sure there are no little ones around. Do not play with the candles just watch it, again have no things around it that will not catch on fire like maybe your hair or any long sleeves and then it should be safe to enjoy this

In the second experiment, The condensation shows that there was water present as it was left inside the beaker along with soot, Both of these things show incomplete combustion. In the Third experiment, It showed lack of oxygen which the candle needed in order to burn this also showing incomplete combustion. In the forth experiment, The color change in the BTB indicates the effects of Carbon Dioxide. In the fifth experiment, the candle burns fuel because it creates the candle to gain heat and melt. In the sixth experiment, it showed the presence of carbon dioxide due to the color change.

The question that was resolved by this experiment was, “does different temperatures affect how long the illuminating process in glow sticks lasts?” In this experiment the hypothesis was, if the temperature is cold (5 degrees Celsius), then the glow time of the glow sticks lasting will increase because the molecules are moving slowly and the cold water is dragging out the reaction time making it last an extensive amount of time. The independent variable was the temperature of the water in the glass cup while the dependent variable was how long the sticks glowed. Some controlled variables included 235 milliliters of water in each glass, the brand of glow stick used which was glow play, and the color of the glow sticks which was pink. The controlled group was the glow stick in the room temperature water, and the experimental group was the different water temperatures. During this experiment make sure to crack the glow sticks and shake it well before putting it in the cup.

The purpose of this lab was to observe the burning of a candle and to determine the rate at which a candle burns. In order to begin, we tightened our candle into the clay located in a weight boat. Then, we measured the initial height and mass. The original height was 8.5 cm. The original mass was 9.26 g. In addition, we noted that the candle was made of wax, had a spiral pattern, was pink with white stripes, and had a pencil-like shape.

*Note: This spell was designed for good luck, but you can design it for to suit your needs by the color of your candle and herb. Check the Color Correspondence and Herb Correspondence tables in the Appendix.

I chose the topic do white candles burn faster than colored ones because whenever my mom burns candles, the white candles sometimes tend to burn faster than the colored ones. So for this year’s science project, my essential question is ‘Do white candles burn longer than colored ones?’ I’m going to conduct this experiment twice to test accuracy and just in case, if possible, if I made any mistakes.

According to the results, the hypothesis is correct, as the larger the container, the longer the flame is extinguished, the slower it will be extinguished. When the candle is covered with a bigger container, the amount of oxygen is greater near the candle. The candle uses oxygen during the ignition process as it is an important factor to keep it burning. Therefore, this amount of oxygen requires a longer period of time to keep the candle lit for a slower period of time compared to a smaller container that will determine the amount of oxygen less close to the candle and thus the candle will use this quantity in less time for ignition.

In past years most candles were made from tallow. Tallow came from cows and sheep, in the earlier times of the Egyptians and the Roman’s. These early candles didn’t burn well and normally smelled worse. The Roman Empire was the first to provide evidence of a candle that resembles the candle today. They melted the tallow until it was a liquid and poured it over fibers of flax, hemp, and cotton, which were used as a wick. These candles were used in religious ceremonies as well as lighting for their travels and houses.

Project Requirement: As per project requirement as a team we need to select a project based on different criteria like timing of project, complexity, probability of success and enjoyment of team. We need to execute the project as per the project management methodology and prepare different documents during life cycle of the project starting from initiation, planning, execution, monitoring and control and closure. One of the team member has to take leadership role of project manager and guide the team during project execution. At the end of semester we need to submit a project notebook with detailed summary of project and different documents generated during project.
