Objective: The purpose of this lab is to investigate the relationship between the speed of an object in uniform circular motion (UCM) and the centripetal force (FC) on it. This direct correlation will be calculated by determining our values for how long it may take for any given weight to undergo 20 cycles. Using this…
Research Question: What are some of the properties of ionic compounds? Background: Ionic compounds are formed from a crystal lattice, a cation ionically bonded with anion in an alternating three-dimensional pattern, whose bond strength determines the compound’s properties. Ionic crystals have high melting and boiling points. They conduct electricity when dissolved in water or melted.…
Background Osmosis is the movement of water molecules from a high-concentration region to a low-concentration region (Guyton and Hall, 2021). Only the free water molecules in the solution can move; the solute molecules remain stationary (Raven, Johnson, and Mason, 2014). Osmosis continues until the concentration of water molecules on either side of the membrane reaches…
The idea of destiny has been connected to the notion of stars, which some believe control human life. This gives rise to the idea of “star-crossed” lovers—those for whom a sorrowful fate seems inevitable. In the play Romeo and Juliet, the characters suffer a tragic ending: death. However, many argue that it is not destiny…
Throughout his works, the postmodern thinker Jaques Derrida explores a variety of thoughts around a wide variety of topics. While all writings present new understandings applicable not just in theory but in daily life, some of his writings most grounded in daily human experience are those he presents around his aporias, or puzzlements. Within these…
When describing the state of nature, Hobbes famously describes a state of war which is “nasty, brutish and short.” It is understood by Hobbes to be a state of constant fighting between all members of society- a constant war between everyone. However, in Foucault’s reading of Hobbes, he critiques this conception of the state of…
The “docile body” as conceived by Foucault is a person who, as a result of disciplinary power is molded into someone who does exactly what they are supposed to in exactly the way they are supposed to. This concept of a docile, malleable, body is applied originally to that of soldiers, where Foucault describes training…
The ‘prisoner’s dilemma’ is a hypothetical situation often used in the context of Hobbes’ Social Contract Theory. It is a seemingly simple situation which carries significant implications which add to the understanding of Hobbes’ conception of the state of nature as a “‘solitary, poor, nasty, brutish, and short’” (Rachels, 2012, p. 83) state of war,…
Model 1: What impact does temperature have on NH4CL solubility in water? Model 2: How will changing the limiting reactant impact the procedure’s outcome? Model 3: How does the number of intermediates involved in the reaction affect the accuracy of Hess’s Law’s prediction of the enthalpy change of a chemical reaction? Introduction Three different experiments…
Comics tend to garner a bad reputation among casual readers because of a misconception that comics are only ever about light and playful topics. The use of drawings and illustrations, especially those in a traditional “cartoony” style, also veers away from those looking for a more serious topic to read. However, the Graphic Novel trilogy…
Hamlet, a world-famous play by William Shakespeare, is a very dark and somber piece of work. With murders and lies almost seeming to be a common topic throughout the play, it would be an understatement to say only Hamlet was the true victim in this theatrical work. Characters like Horatio, who did not provoke anyone…
PURPOSE The purpose of the experiment is to validate the lens equation and the magnification equation by measuring the image distance from a fixed focal length and the object distance from the thin lens using concave and convex lenses. QUESTION How does an object’s image position and size (magnification) vary with different object distances from…
On July 4th 1776, the Declaration of Independence was adopted by the Continental Congress, the document undoubtedly influenced by the work of Thomas Paine, if not written by him like some historians theorize. A few months before in January 1776, the pamphlet Common Sense was published by Thomas Paine during the American revolution and was…
Foreword This laboratory involves the use of an enzyme that will react with hydrogen peroxide. The enzyme is catalase, and the substrate is hydrogen peroxide (H2O2). The reaction is as follows: catalase 2H2O2 2H2O + O2 Ingested hydrogen peroxide is a poison, while external use of this substance is not. However, the generation of oxygen…
Permeability of a cell to solutes in an aqueous solution depends upon the physical and chemical make-up of the membrane. The maintenance of the living cell depends upon the continued presence and functioning of a selectively permeable membrane. If the nature of the membrane is altered in any way, this may affect it’s permeability and…
PURPOSE The purpose of this lab is to quantitatively investigate how the mass of a coil spring and the length of a pendulum affect the period of oscillation of a system experiencing simple harmonic motion. In this lab, I will establish a mathematical connection between the period and these variables through the execution of this…
Introduction: Unless you’re a coin collector, you probably think all United States pennies are pretty much the same. To the casual observer, all the pennies in circulation do seem to be identical in size, thickness, and composition. But just as elements have one or more isotopes with different masses, the pennies in circulation have different…
In this experiment, you will determine the mass percent of carbon produced in the decomposition of sodium bicarbonate produced from the following chemical equation: Reacting sodium bicarbonate (sodium hydrogen carbonate) with sulfuric acid will produce a salt, water, and carbon dioxide gas. According to the Law of Definite Composition, the mass percentage of carbon produced…
Purpose: To find the specific heat capacity of a substance Principle: According to the principle of thermal energy exchange, when thermal energy is transferred from a warmer object to a colder object, the amount of thermal energy released by the warmer object is equal to the amount of thermal energy absorbed by the colder object.…
Comparing the refractive index of a medium with its critical angle PURPOSE This lab was conducted to prove a relationship between the critical angle and index of refraction of a ray of light passing through a denser medium to air. QUESTION How does the critical angle vary across media with different refractive indices? BACKGROUND KNOWLEDGE…
