Glow Sticks Experiment

What is a glow stick? Glow sticks are very popular for Halloween parties and discos for schools and just random parties like if you’re turning 30 or 40 and so on. A glow stick is a short term light that glows in the dark. Glow sticks are a tube that once slightly bent will cause the glow stick to glow.

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

When analyzing the IR spectrum of Ruthenium complex with DMSO, the prominent peak is presented at 1105.54 cm−1. This peak indicates that S=O bonded in DMSO. For DMSO, the frequency is around 1050 cm−1. From our spectra obtained for DMSO where the S=O peak is at 1017.65 cm−1. Since the bond appears at a higher frequency, this shows that the bond is strengthened by the reaction. This indicates that when the copper metal was combined with DMSO, it bonded with the Sulfur atom. Combining ruthenium with sulfur atom caused it to donate a pi electron as a back donation.

Energy is a concept.� Most definitions of the word energy fail to provide its exact meaning when applied to scientific matters.� In science the word energy is a concept that expresses two measurable properties, heat and work.� Here is the relationship of energy, heat and work:

Change in color once chemicals were combined (experiments b,c,d,e,f,g,h,j,l); Precipitate formation (experiments g,j,l), and formation of gas bubbles (experiment a).

The purpose of this lab was to carry out a systematic series of experiments to determine which chemicals and at what ratio produce chemiluminescence, and then to manipulate reaction conditions to extend glow time or brightness.   The variables for day one were chemicals used, amount of chemical, order of addition, and stirring the substance or not. The main variables in day two were heating or cooling chemicals, order of addition, and stirring. The best trial for day 1 was trial 13, which was 2 drops of H2O2, 2 drops DMSO, 2 drops HCl, 2 drops NaOH, and 2 drops Bleach, in that order, added to 10 drops luminol, and then stirred.

The “Coolest” Experiment Ever is a science fair project to determine whether or not mints have a cooling effect or is it just a sensation. The predicted outcome of the experiment is that if we add mints to a hot glass of water, it will cool down more than the glass without mints. The reason being is because mints contain menthol, a substance that melts just above room temperature. It triggers a cold-sensitive TRPM8 receptor which produces a familiar cooling effect. The basic procedures of this experiment is to fill two glasses with hot water, and add five mints every five minutes. After every trial, check the temperature using a thermometer. Record all the observations you have made with a critical eye. The predicted outcome of the experiment

Margaret Milcoff, a student of Mill Creek Middle School, participated in an activity called the science fair. Her topic was “Does temperature affect the growth of basil plants?” Margaret has a rich desire to absorb all of the facts of the future, so she did this particular science fair experiment to find out if simple plants, such as basil, would be able to survive the deadly affects of global warming. Margaret used the scientific method through her trials of the science fair. So without further a due here is Margaret’s very successful and meticulous science fair journey.

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

Light can be produced in many different ways, including incandescence, phosphorescence, and fluorescence (Gunderman 1). Incandescence is when heat makes an object release light, like the filament in a light bulb. Phosphorescence is when a material absorbs energy and then releases it slowly over time, like glow-in-the-dark toys. Fluorescence is when a material absorbs energy and releases it quickly as light (Gunderman 1). Fluorescence is the process used in glow sticks (Science Fair Projects 1). The fluorescent dye in this experiment’s glow sticks released yellow light. Different color glow sticks are made with different dyes (Harris 2).

For the experiment, we attempted to burn the candle for 5 2-minute time periods. As we were burning the candle, here were our observations: the wick is burning, burning is taking place inside the candle, wax is melting, candle is getting shorter, most heat released above flame, wick is slanting, wick is blackened,

The observations acquired from this lab indicates that the test tubes that have a minimal amount of oxygen had an increase of soot production and test tubes that experienced complete combustion had no sort of Soot production whatsoever. The observations demonstrates that when the oxygen levels decrease, the production and soot will increase. (Refer to Appendix B Figure 1). This is because within incomplete combustion, the byprouctions will be Carbon, Carbon monoxide, Carbon dioxide and water, all together to produce what is called , Soot. On the contrary, test tubes that experienced complete combustion had byproducts that were only Carbon dioxide and water, which therefore no sort of soot was produced.

If you used to lay out in the sun to achieve a golden "healthy" glow, then your skin may be finally showing the signs that your bronze glow wasn't such a healthy achievement after all. While you can't turn back time, the good news is that with today's modern skin-care products and medical techniques, you can begin to repair your sun damage and have healthy skin again. Follow these tips for repairing your skin and helping it gain a real healthy glow again and not the bronzed glow that you just thought looked healthy years ago.

I had trouble with the slime experiment. I had trouble with the slime experiment because my slime kept getting liquidy and sloshed around in the cup. Another reason why I had trouble with the slime experiment because I think I added too much detergent to the glue. That is why I had

From Criminal Minds to CSI, we have all watched the criminal investigation shows on television and loved watching gorgeous actors play scientists, who in the real scientific world would have no clue as to what they’re doing but surly we have all been curious, “How do they make blood light up?”. The whole idea of forensic science has always interested people and that is what keeps those television shows running. The key to getting and creating any chemical reaction that glows is just a few chemicals at the right temperature and a few simple substances thatcan transform a simple concoction into an eerie looking splotch of blood or human fluid.
