How Temperature Affects A Glow Stick Glow sticks come in many shapes, sizes, and vibrant colors and are a quite popular object to take to places such as parties. There is one problem with all glow sticks that everyone has to face and that is having it last for an extensive amount of time. The scientific question being asked in this experiment is, how does temperature affect how long a glow stick stays lit? To solve this problem an experiment to see which temperature of the water a glow stick…

research which I carried out for the science investigation focused on heat energy which related to conduction. The investigation consisted of finding out which coloured ice cube (yellow and blue) with 1, 2 and 3 drops of colour melted faster on metal and plastic. The energy source used to identify which coloured ice cube melted faster was heat from the sun. Conduction occurs regularly in nature and is the transferred from heat through physical contact. Particles that move faster near other…

JR is a 26-year-old Persian male who lives in Fresno. This interview took place on 03/17/17 at 1330. The story of his life based on the interview showed that this person is in recovery from a very heavy addiction to drugs. When I asked the person about his life story he gave me the following information. I was three years old when my mother divorced my father because of his addiction to drugs. I grew up mostly in my grandparent’s house in Iran with my mother, until my mom decided to remarry her…

Winterkill of Iowa athletic fields is dependent on several factors. Abiotic and biotic stress conditions before and during the winter season can lead to turf death the following spring. This is particularly true of perennial ryegrass, tall fescue and annual bluegrass, which is very susceptible to winter stresses common to Iowa. Winterkill can be a result of poor freeze acclimation and direct low temperature kill, crown hydration, hypoxia (lack of oxygen), desiccation, or diseases like snow mold.…

In the position statement exertional heat illnesses created by the following authors Helen M. Kinkley, Joseph Beckett, Douglass J. Casa, Douglas M. Kleiner, and Paul E. Plummer they all went to different universities but combined ideas to make this position statement. The position statement was written because it’s to help prevent, help recognize and treat exertional heat illness. Since this position statement was created it has helped some athletes, athletic trainers, allied health care…

Comparing Your Options For Replacement Windows If you're looking into replacement windows for your home, you can choose from wood, aluminum, or vinyl. You'll want to consider the appearance of the frame and how well it insulates against heat loss. Here's a look at how these windows compare. Wood Frames Are Traditional If you have an older, historic home, then wood frames are probably the best type because they have a more traditional appearance. Wood is the original material for window frames…

chemicals is often hydrogen peroxide and the other active ingredient is a harmless chemical named phenyl oxalate ester. The chemical reaction between these two substances produces enough energy to make light, but it doesn't create enough energy to make heat or explosions. There also need to be dye in a glow stick. The glow stick gets color when the energy created by the chemical reaction gets the molecules of the dye moving. There are two internal capsules that separate the chemicals. One is…

Discussion: In sample, B there was 16% salt, which is unnaturally higher than the global average of 3.5%. When I asked about the reason of this, I found that the water was artificially created. This was also the case of Sample, A which had 9% of salt. That is about 3x the amount of salt from the global average. All though this is not an experiment with data, that we can apply to real life, it was still great fun to do the experiment and the lessons I learnt will stick with me for a long time.…

Weather and season together are used as a metaphor to reflect characters’ inner feelings and set the tone of the crucial point in the development of the relationship between Gatsby and Daisy. The rain and sunshine when Gatsby and Daisy first meet after five years reflect Gatsby’s nervousness at first and set the emotional tone of the relationship between Gatsby and Daisy from embarrassment to comfort in chapter 5. As a very crucial point in the novel, the setting of Gatsby and Daisy’s first…

Thermodynamics highlights the stream of science attentive to heat and conversions to different forms of energy and work. Not only does the thermodynamic state define volume, temperate and pressure, it will contain heat sources giving a capacity, and change state. The idea of thermodynamics is for the system to adjust itself back into its original state of an equilibrium. Through expressing the laws of thermodynamics, it is apparent that heat energy is important in the world in order to achieve…
