The Candle Affect The Duration Of Ignition Essay

Heat the bottom of the candle and secure it to a cardboard square on your lab counter. Light the candle and allow it to burn for several minutes. Note any changes. Briefly describe the burning candle.

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

The daily life of a candle maker was like a peasants. The houses were not very sanitary and nice. They had dirt floors and used mud the way we use cement today. The food was bland and plain. They usually had small gardens that had little vegetables in them. Also, they couldn’t have livestock unless they had enough money which very few peasants had. Clothing was plain with little pattern.

1. Place a small amount of wax from a birthday candle into a test tube. Heat gently over a burner flame until the wax melts completely; then allow

. At in station 1and 2, students are encouraged to set their hypothesis and write down their predications, what they think? dose the wax have high or low melting point and boiling point, the third stations, dose the acetone conduct electricity or not?. To help students construct their explanations, I asked questions that push students to make connections to the real world. For example, in video 4, minute 0:56, I asked students what is the conductivity mean, the student answers, flow of electrons, To get him to

This article focuses on the Revolutionary period of Colonial Williamsburg when candles were a primary light source in homes. At this time in history there were four primary substances used in making candles, spermaceti, tallow, beeswax, and myrtle or bayberry wax. The three latter substances were produced in Virginia. Methods of making these candles and how they were shaped are described in the article.

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.

The jar was held in place so that it did not obstruct airflow in straw when it was placed over the candle. The process of trial 1 was repeated three times with the additional straw.

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

You then take scissors or a knife and cut one hole on the side of the turkey baster or car filler. The car filler/ turkey baster should be facing upwards with the open end of the turkey baster facing up with the handmade hole on the side of it. Then you take apart the spark igniter and reassemble it in the turkey baster or car filler so that the part you spin to create the spark is the only part sticking out of the handmade hole. That is when you use the screwdriver and wrench to take apart and put back together the spark igniter. The cannon is finished when the spark igniter is properly assembled and is able to create a spark. To finish the experiment you then need to add ten to fifteen drops of rubbing alcohol inside of the turkey baster or car filler. When you are in a safe open area where no one is around you can then spin the spark igniter knob really fact to create a spark with the rubbing alcohol and launch the ball out of the cannon. The cannon won’t work properly if there is a dent in the ball. The ball won’t launch if there is a dent because the dent allows oxygen to get into the cannon and the combustion won’t work

The fun filled journey you take when you burn a Prize Candle speaks to your sense of sight, smell & touch.

In this project we examined three explanations that talk about (a) candle(s) in a jar and their investigation reasoning to why the labs they did were concluding in such a way. The first explanation resulted that the candle inside the jar took up all the oxygen molecules inside the flask which then lowers the pressure inside and the higher pressure outside the flask is what causes the water to rise up. The second explanation resulted in that the air pressure increases inside the jar because of the heat from the candle, which causes air to come out of the jar and once the candle cools down the pressure decreases and the pressure outside the jar increases which results in pushing the air in and making the water rise up. The third explanation resulted in oxygen inside the flask becoming carbon dioxide which then dissolves in water causing the air pressure to decrease under the glass and the higher pressure outside the flask pushed the water up the flask. I believe that explanation number three is right because the flame causes carbon dioxide to be created and that

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.

At one time, scented candles were a rare luxury to be enjoyed only by the rich while the rest of us made do with the ordinary white candles during power cuts and at Christmas time. However, that has all changed, and an endless variety of fragrances are filling our homes and relaxing us. Candles are just one of these sources of wonderful smells, but they are also a very popular source, partially because of the number of different forms in which they are available but also because they look so good with their burning flame.

They are given several minutes to explore. Students must find a desirable question to research and conduct the experiment based on their observations.
