This scientific experiment will entail the rate at which ice will melt with different types of salts that include, table salt, sea salt, and rock salt. Salt melts ice essentially because adding salt lowers the freezing point of water. Although we know that salt has the ability to melt ice, we are testing whether sea salt, table salt, or rock salt melts ice more efficiently by calculating the amount of time it takes to melt the ice. We will begin by placing the same quantity of each type of…

Purpose Statement: The main ingredient in my favorite seasoning, Adobo, led me to choose salt as my topic. After doing background research, I learned there were three ways of making salt and the one I found most interesting was solar salt. My decision to focus this paper on solar salt was also influenced by the fact that I never bothered to know how salt was created or obtained, and I like learning about environmentally friendly products. My intended audience is the class and the professor. I…

looked at for its physical characteristics. WD has light, tan color and a soft texture, resembling the wood of a pine tree. The density of it was also calculated and had a 20% error. Through the acetic acid test, PE mirrored the characteristics of sodium bicarbonate. They both create a large chemical reaction in which fizzing and bubbling occur. The Australians will get LF, MA, and WD through a density comparison, and PE through an acetic acid…

Every year during winter months, icy surfaces create a dangerous problem for drivers and pedestrians. Icy roads and sidewalks can become very hazardous for travel. A solution must be implemented to mitigate risks associated with winter travel. This problem is relevant to the experiment since I will be testing different methods of melting ice. The solution resulting from the experiment can be used throughout the world to make our roads safer. The literary reviews for this experiment are from…

How To Pass A Hair Follicle Drug Test Used by employers, corporations, law enforcers, and even parents, hair drug testing is one of the growing methods for drug testing. With it, someone can be tested for drug use as far as 90 to 120 days ago. And unlike urinalysis, there’s no way to adulterate or dilute the hair samples to mislead the results. Now, you might be worried and asking: “How do I pass a hair drug test test!?” First off, know that this isn’t a fool-proof method, but many have had…

Investigating if dissimilar sized candles have the capability of drinking equivalent quantity of water. Aim: The drinking candle science experiment is quite enthralling, as when performed, you'll observe a burning candle drinking up all the water kept beneath it due to the behaviour of the atmospheric pressure. The aim of this experiment is to investigate if unlike sized candles have the capability of drinking the same amount of water. Hypothesis: With all the information given on different…

Physical properties of PHB: PHB physical properties similar to polypropylene. However, PHB is perfectly isotactic and does not include any chain branching like, for instance, PE. During processing, it flows easily. It is insoluble in water and soluble in chloroform and other chlorinated hydrocarbons. It exhibits good barrier properties against oxygen and compared to other biopolymers. It possesses better physical properties than polypropylene for food packaging applications. (Chaijamrus & Udpuay…

Plant Material Collection Fully grown whole plants of Tribulus terrestris Linn. were collected from different localities of Chennai, Tamilnadu. The fruits were separated out from the plants and washed in running tap water to remove adhering dirt and soil particles and dried first under shade in room temperature and secondly in a hot-air oven for complete drying at 50-60˚C. The dried fruits were made into coarse powder by grinding and stored in labelled bottles for further study and…

This experiments goal was to successfully produce ZnI2 by using Zinc Sulfate (Heptahydrate) and Barium Iodide Dehydrate, which Jessica and I did with acceptable success. The definition of acceptable success for this experiment is measured by how close our percent yield was close to the ranges provided (0-2% being considered excellent precision and etc). Our percent yield was 92 % meaning that it was an acceptable, but not exactly as close to what we wanted it to be. In order to try and figure…
