Experiment 4A – Counting Atoms in a Chemical Reaction Purpose: The purpose of this lab is to create an experiment where zinc reacts with hydrochloric acid in order to find out the number of moles and atoms of zinc reacted. This can be accomplished by weighing the sample before and after the reaction with hydrochloric acid. Data: Material Mass in grams (g) Initial mass of dry beaker 49.37 Initial mass of dry beaker + zinc 51.03 Initial mass of zinc 1.66 Final mass

Salinity Experiment Aim To determine a method of measuring a soil sample’s salinity level in order to measure 3 samples’ salinity level. Hypothesis I think that by running a current through a salt solution and measuring the resultant amperage‚ a pattern in the recordings will help find a soil sample’s salinity level. Variables Controlled Amount of solution (100 mL)‚ supplied voltage (4V)‚ amount of soil (50 gm) & water (150 mL) in soil sample’s solution. Independent Amps recorded

Purpose: To find the initial velocity of a marble leaving a ramp using time‚ range‚ and background information learned in class. Equipment: The equipment used in this experiment was a toy track and ramp‚ a small marble‚ multiple Physics textbooks‚ meter sticks‚ bright-colored cardstock‚ masking tape‚ sidewalk chalk‚ plastic bag and a cloth. Procedure: Our experimental values include the height that the marble would travel‚ y= 88.1 cm‚ and our ramp angle‚ θ= 44.0°. These independent variables

characteristic that seems to be consistent through time is a nurse should be caring. Jean Watson incorporated a theory- The Theory of Human Caring. Watson (2002) developed a theory in which nursing is centered around helping the patient achieve a higher degree of harmony within mind‚ body‚ soul‚ and this harmony is achieved through caring transactions involving a transpersonal caring relationship. According to Watson‚ caring consists of carative factors that result in the satisfaction of certain human

The testing for the Doll Test OR Eye Color Experiment resonated more with children is because children are brought up in discrimination house hold. Doll test told that how equal size the dolls were except for their color‚ to test children’s racial perceptions. Their subjects‚ where at least the children between the ages of three to seven‚ were asked to identify both the race of the dolls and which color doll they prefer. Eye Color Experiment talks about on how children treated each other by eye color

DOE - Design of Experiment DOE is an approach used to identify factors/steps that are contributing most to an observed variation in product specifications. The classical DOE focuses on identifying the factors that affect the level of a product/process response‚ examining the response and forming the mathematical prediction model. The modern DOE‚ introduced by Genichi Taguchi in early 1980s‚ applies in both product and process development to identify the factors that affect the variability of the

The main focus of this experiment was to find the relationship between temperature and the enzyme activity of amylase. This was achieved by attaining amylase enzyme‚ starch solution and potassium iodide (determines if enzymes hydrolyses the starch solution)‚ water bath and a hot plate. The temperatures used for this experiment were room temperature‚ 37oC‚ 60oC‚ 80oC‚ and 90oC. The hypothesis developed was that as the temperature increased‚ so will enzyme activity. Therefore‚ the ability of the

Breaching Experiment In the eye contact experiment I decided to do this in a room with about six of my friends while watching the All Star game‚ I used my Girlfriend. I waited until everyone was focused on the game and then begin to stare at her from across the room‚ at first her reaction was to wave at me and smile then she started to look around to see if I was starring at someone else‚ then she told her best friend "I don’t know what’s his problem‚ he is being too weird." I extended my eye contact

In the 1890’s a famous psychology experiment was conducted by Ivan Pavlov which demonstrated classical conditioning in dogs. According to The Free Dictionary‚ classical conditioning is‚ “a learning process by which a subject comes to respond in a specific way to a previously neutral stimulus after the subject repeatedly encounters the neutral stimulus together with another stimulus that already elicits the response.” Around the 1920’s‚ famous psychologist John B. Watson along with a graduate student
