Candle Color Lab

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

For part one of this experiment, I only experienced separation of colors with the green and brown M&M’s, along with the yellow food coloring. The green M&M separated into yellow and blue, with blue travelling farther up the paper. It is not surprising that green separated into blue and yellow because those are the primary colors that make up green. The brown M&M separated into red and orange, with the orange travelling farther up the paper. Finally, the yellow food coloring separated into yellow and red, with yellow travelling farther up the paper. This could be because it was such a concentrated, small amount of food coloring. The colors that didn’t travel very far up the paper, such as orange and brown, are probably less soluble than the others, like blue and green.

Introduction: This experiment aims to discuss whether the thickness of a candle influences the time of burning. A candle burns by melting the wax near the wick. This liquid wax is then drawn up the wick by capillary action. The heat of the flame then vaporises the wax. Previous results showed that wider candles burnt slower than thinner candles.

Every cell transports materials in and out throught something called a membrane. There are many different methods of transport in the cell Saccharomyces cerevisiae (Serrano, 1977) We want to know does adding higher concentrations of azide more effectively block dye transport? We tested the transport of dye in yeast cells with a metabolic inhibitor. When we did this we showed no difference in the absorbance between different azide solutions, and our control. From this we concluded that azide has no effect on the transport through a yeast cell membrane.

The given purpose of this lab was to separate and identify the pure substances in the sludge, however, the lab had a larger purpose. In this lab, we used our newly-found knowledge of characteristic properties to fulfill the given purpose. It taught us how to use critical thinking and grit when faced with a challenge, and to use all of the tools that IPS this year has taught us. In a nutshell, characteristic properties are properties that will remain the same, no matter the volume of a given substance. Many scientists and students use these valuable properties to identify substances because the property will remain the same.

According to the data it looks like unscented candles burn a little bit faster than scented candles but they both pretty much burn at the same rate of speed. Also one reason why the unscented candle burns quicker is because it’s not as processed as the scented candles are with all the scents and colors.

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

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 memorandum is to explain the results of the night light project. The experiments for the lab were carried out on November 1st, 2016 with Brian Tran and Brady Lucia as lab partners.

element of a candle can affect how fast it burns, I wanted to see how this experiment turns out http://candles.lovetoknow.com/Do_White_Candles_Burn_Faster_than_Colored_Candles

To fully comprehend the mechanism of the bleaching process, it is essential to know the structure of the blue food dye. For this experiment, the FD&C number of the blue food dye used is Blue 1, its structure is shown as below: It could be seen that the structure has a conjugated system, which is a system of connected p-orbitals. This means that the single and double bonds alternate throughout the entire system. No electron absorbs more energy than the other because the π-orbitals overlap effectively and all π-electrons in the system are distributed above and below the molecule. The electrons are delocalized in the line of the bonds, which enables the electrons to jump between energy levels.

In the Eye Color Experiment, a connection between race and self-perception or self-esteem can be exposed through the way the children behaved. The children did better in the card game when their eye color was supreme and worse when their eye color was not supreme. This is due to the fact that the children felt a greater sense of self-esteem when they were in the supreme group and a much lower sense of self-esteem when they were in the insignificant group.

Purpose of this lab was to see which accelerants best burned the house and the different stages of burning. The accelerant that our group used was alcohol. It burned faster than the other accelerants. Other groups used accelerants such as: acetone, gasoline, and hand sanitizer. The acetone burned quickly and almost evaporated instantly. The hand sanitizer and gasoline were both quicker in the spread of the fire. Though alcohol and gasoline ignited quicker. For our group flashover only lasted eight seconds. Flashover happened so quick because there was complete combustion. You could see the flash over occur when the whole house was engulfed in flames as well as the whoosh sound. There was no conduction that we could physically touch unless we

I think that colored candles will not have the same effect as white candles. I think that colored candles will burn faster.

Incandescent light bulbs use a wire filament heated to a high temperature in order to give off light. The filament has an electrical current sent through it, and is protected from oxidation by a glass bulb or a quartz bulb. On average, the incandescent bulb uses 60 watts and costs 11 cents per kilowatt hour. On average, one bulb costs $1. 90% of what an incandescent light bulb produces is heat, which wastes a lot of electricity. Also, the lights produce sustainable levels of CO2. They have an average lifespan of 1,200 hours.
