Cool Mints When eating a mint a cool sensation bursts through one's mouth, but is that mint really making their mouth cold, or is it just their mind playing tricks on them? This science fair project is questioning whether or not mints really make one's mouth cold. To test this the theory, the project will include a glass of lukewarm with mints added in every few minutes. How will adding mints in a glass of room temperature water affect the temperature of water? Why does it feel like mints cool…

In the experiment, I tested how soapy water would affect the amount of droplets the penny can hold. The results of my experiment show that the penny holds less droplets of soap water. When the soap is added to the water, the soap collides with water breaking down the tension. As a result, it harder for the droplets to hold together. To find whether my hypothesis was right, I did several of trials to figure out whether my hypothesis was correct. The trials were used to show how soap can change…

Minoxidil, an antihypertensive vasodilator medication, which was developed in the 1950’s by a company called Upjohn originally used to treat ulcers. During their experiments with dogs, they figured out that it did not cure ulcers, but acted as a vasodilator. Due to this recent discovery, Upjohn was able to develop a compound called Minoxidil in 1963 as well as being able to synthesize over 200 variations of the compound. The molecular structure and compound of Minoxidil is C9H15N50, made…

innate protein particles or aggregates.However, there is a mechanistic difference between the two aspects. In the case of a pure solubility issue, i.e. a protein becomes insoluble in a certain solution (no changes in protein structure and integrity) and a solid phase is formed, a strong dilution of the system may lead to the dissolution of the protein. In such a circumstance, the term “protein associates” may more appropriately describe the formed protein solid .In this instance, protein…

air to pass through. The semipermeable membrane covering the outer and inner shell membrane has an outermost coating called the cuticle to keep bacteria from entering the pores (Nelson, n.d.). The experiment will be conducted to determine which acid or base corroded most of the eggshell in the given amount of time. There will be a control group placed into water to compare to the variable groups Diet Coke, Red Bull, and lemon juice. The dependent variable is the amount corrosion on the…

light gray color and the strips of zinc added to solution were approximately 5 cm. When zinc was tested with water there were no noticeable characteristics of a reaction occurring, such as bubbling or a color change. When zinc was added to the weak acid H2SO4, at first there was no noticeable reaction, however,…

water pollution are arising and becoming more frequent from human actions everyday. One example of this is acid rain. Many scientists believe that the recent drop in aquatic life in our bodies of water around the world is owed acidic rain lowering the pH levels. Acid rain produced by coal burning industries flow into all bodies of water after falling on forests, fields, buildings, and roads. The acid rain eventually raises pH levels of surrounding bodies of water leading to it 's many negative…

reaction and see how different properties - such as concentration and temperature - affect the reaction rate. This was to enhance understanding and gain knowledge of how certain properties affect reaction mechanisms and activation energies, and how acid-base equilibria behaves. The data generally supported the hypothesis. It can be clearly seen that higher molarities of t-BuCl gave faster reaction rates, and it is an even clearer trend between the temperature of the system and the reaction…

Is Perrier Bad for You? Perrier is carbonated bottled mineral water sourced from the Les Bouillens spring in Southern France. Although the water from the spring is already naturally carbonized, carbonic gas is added to it again as it is bottled. Because of the many health benefits this water promises, it became very popular among Americans who wanted to lead a healthy and active lifestyle. Perrier soon became a widely-used substitute for soft drinks or cocktails and has gained a reputation for…

Building, Victoria Street, Stellenbosch University. Rudi Scholtz, Thelema Mountain Vineyards, Helshoogte Pass, Stellenbosch. August 2015 ABSTRACT Malolactic fermentation is the conversion of harsh and acidic malic acid to a more desirable form of lactic acid in wine by Lactic acid bacteria, after the completion of alcoholic fermentation. This reaction can take place naturally in wine, proving to be very unpredictable and not always favourable, or by inoculation with bacterial cultures.…
