Abstract The purpose of this experiment is to study automatic processes by replicating the previously carried out Stroop effect by using numbers. This experiment was conducted by recruiting 8 participants (4 males and 4 females), who are working in a head-office of Save the Children Organization in Yangon, selected by …

Introduction This experiment is based upon a discovery made through the isolation of PbI2 using a particular scientific method, which studies ratios of lead to iodine. Precipitation reactions occur when oppositely charged ions attract and form an insoluble ionic solid. This experiment examines the precipitation reaction between lead (II) nitrate, …

Introduction: Summer vacation has long been associated with sleeping in, lazy days by the pool, hanging out with friends, learning the vocabulary of harmonic motion, constructing cheesy experiments, and graphing data. Summer 2012 will be no exception. First, I want you to read 3 pages on the internet (Step 1 …

Introduction This experiment will observe the growth of garden beans over a period of time. It seeks to address the question ‘how fast does a garden bean grow?’ Does it grow in a constant, linear manner, such as one (1) cm. every twenty-four (24) hours or sporadically, hitting growth spurts …

In this experiment, we determined the effect of a change on a system at equilibrium and correlated that to Le Chatelier’s Principle. Introduction Le Chatelier’s Principle says that when a system at equilibrium is put under stress, it will correct itself to relieve the stress and reestablish equilibrium. Equilibrium can …

I. Introduction: This lab is intended for designers that have time to check filter theory as shown in the college communications textbook. The pre-engineers are going to build a Narrow Band Pass Filter to compare theory with designed circuit behavior. By doing this the students will be able to better …

Experimental data from nucleophilic substitution reactions on substrates that have optical activity (the ability to rotate plane-polarized light) shows that two general mechanisms exist for these types of reactions. The first type is called an SN2 mechanism. This mechanism follows second-order kinetics (the reaction rate depends on the concentrations of …

Abstract Intent: To conduct an experiment to prove the yielding support distance is directly proportional to the period. Results: d(m)| Time for 20 Oscillations (s)| Time for 1 Oscillation T (s)| T2(s2)| d3(m2) x 10-3| | 1| 2| 3| Average| | | | 0.24| 31.50| 31.47| 31.44| 31.47| 1.57| 2.46| …

The aim of this experiment was to determine the density of water and, of unknown solutions, by being as accurate as possible, by pipetting and weighing the solutions. Density if defined as “The mass per unit volume of substance; common unitg cm-3” (Lewis. R and Evans. W., 2011). As the …

The purpose of this experiment is to determine the weight (density) of certain liquids and solids in chemistry. These liquids include; Water, Hexane, Carbon Tetrachloride, and solids include; Copper, Zinc, Lead and, Aluminum. It’s important to know the weight of these products so you can properly conduct experiments and make …
