Conclusion: 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.

Scenario: In this experiment, you have been asked by your teacher, to investigate the design of a small-scale airbag system they want to produce as a child safety device to put into baby strollers. Because of sodium azide’s toxicity (which is used in many vehicular airbags), it is suggested you use

*Based on the results of the melting point, my compound was thought to be A piece of filter paper was placed on the top of the funnel, placed on top of a filter flask with a stopper, and clamped to a ring stand

In the industrial revolution Gas lighting was one of the most helpful thing that was ever invented, the person that invented gas lighting was The Scottish inventor William Murdock he first invented gas lighting in his hometown in england in 1792 then he installed gas lighting in an English factory in 1798 but by that time the streets of London, Paris, Baltimore, and the united states were lit with gas lights.

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

Physical and Chemical Change Objective: Recognize and distinguish between chemical and physical changes. Materials: - lab balance - microspatula - lab burner - dropper pipet - 5 test tubes - mortar and pestle - test tube rack - magnet - test tube holder - insulating pad - watch glass - safety goggles - glass square - lab apron or coat - copper sulfate pentahydrate - iron fillings - sodium chloride - magnesium ribbon - hydrochloric acid - paper (5 cm x 10 cm) - silver nitarate - birthday candle - sulfur - matches Procedure: 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

- Results: When liquid wax is exposed to the heat of a match, it transforms back into its original solid state.

Bubbling Bath Bombs Hypothesis What makes bath bombs fizz and bubble? Will a bath bomb containing lime juice rather than citric acid dissolve faster? I think there is a chemical reaction within the bath bomb that makes it fizz, but I am not sure what things are reacting. I also think that

4. Break an Alka-Seltzer tablet into a few small pieces and drop them into the container one at a time. When the bubbles stop add more pieces of Alka-Seltzer to see it again.

Kyle Walker Intro to Anthropology Dr. Jean Marcus November 16, 2012 Cobb Museum Paper The Cobb Institute Museum at Mississippi State University displays items from the Old World and the New World. When I visited the museum I noticed a wide variety of artifacts. The Old world side contained pieces from many

A plastic mold is the only tool you really need to have to make your own citrus bath bombs. Molds can be found on Amazon or you can use a plastic ball ornament. You can also use any other item you might have at home for a mold for this project.

The stock market has impacted The light bulb was first invented by Thomas Edison on December 31, 1879. Before the people were able to have access to a light bulb they revolved around the sun. People woke up and went to work when the sun rose, and they also went home and went to sleep when the sun went down. With the invention of the light bulb people were able to have extended work hours and didn’t have to solely rely on the sun. Today we have been able to put light bulbs in most of the items that we use on a daily basis. People in today’s society rely on a man made light just as much as they rely on the sun. Without a light people would not be able to travel during the night. We would not be able to function in today’s time without a

Chemistry of Glow Sticks Glow sticks, like many other everyday items, have chemistry involved with them. Glow sticks were discovered by Edwin Chandross in the 1960s. He was a young chemist at Bell Labs in Murray Hill, New Jersey. Edwin Chandross actually discovered the glow stick on accident. All along he was just trying to find a general way to explain chemiluminescence. By mixing florescent light and hydrogen peroxide with oxalyl chloride, he discovered how to create a glowing chemical light. From Chandross original discovery a lab team called American Cyanamid, led by Michael M. Rahurt, created an oxalate ester named phenyl oxalate to replace the oxalyl chloride. This lab team then sold their new product to a group named Omniglow who went

The hypothesis that temperature will affect the length of time a glow stick will last was tested by measuring how long it takes for glow sticks to burn out at different temperatures. Temperature was the independent variable and the time for the glow sticks to burn out was the dependent variable. Five trials (glow sticks) were measured for each experimental temperature. The constant for all of the groups was the type of glow stick. The glow sticks used for this experiment were 10 cm yellow sticks made by

Make sure to pack the mixture very tightly into your mold. It’s important, you want your bath bombs to keep it together.
