Experiment Essay Examples

The course has proposed the idea that science is a social process and asks for agreement. This proposal aligns with the definition of social process as the formation of groups of people and the development and organization of societies, particularly referring to civilizations. The integration of science in the evolving society is discussed in the […]

We are going to investigate the effect that different weights have on my parachute. We are going to construct a parachute and drop it from an unchanged height with different weights attached to it and record the results. To make my experiment, my parachute will be constructed from a black bin liner which will be […]

Method 1 Mass of Mg = 0.12g Volume of Hydrogen = 128cm3 Treatment of results Mg + 2HCl ==> MgCl2 +H2 Method 2 Mass of magnesium from method 1 = 0.12 Weight of boat = 44.17 Weight of boat with solution = 52.84 Weight of boat with salt (MgCl2) = 44.74 Mass of MgCl2 formed […]

I am going to do an investigation into the ethanoic acid content of various kinds of vinegar. The chemical equation for the making of ethanoic acid is as follows: ethanol oxidization bacteria Ethanoic Acid To do this experiment I intend to do an accurate titration using a burette. Hypothesis: I predict that the amount of […]

I am going to do an experiment to test how much sugar can be dissolved in different volumes of water. I will measure different volumes of water out and then add a certain amount of sugar to it and stir it until it dissolves fully, I will keep adding more and more sugar until the […]

For this reaction the heat of dissociation is equal to the HO-OH bond energy. Since it is difficult to measure the heat of this reaction directly, you will use Hess’ Law to determine DHdis. Hess’ Law states that since the enthalpy is a function of state, it does not matter how the final state is […]

This experiment involves three major factors, gravitational potential energy, kinetic energy, and friction. Advancing Physics by Jon Ogborn and Mary Whitehouse has, I feel, the best explanation of the relationship between gravitational potential energy and potential energy. They use a tennis ball as an example: Hypothesis: The significant variables for this experiment are: Height of […]

I will investigate the factors that may affect the period of the pendulum. Each factor will be explored through the preliminary tests and a brief conclusion will be made. Afterwards, I will choose the factor which has shown the strongest results and do further investigations through the main experiment. The results will be recorded; spearman’s […]

To investigate how the size of a parachute effects acceleration of the blutac attached to the parachute. Information I already know The bigger the surface area of the parachute the more the air resistance builds up underneath the parachute, which causes it to float gently to the ground. Safety To get to a sufficient height […]

I intend to determine the optimal rate of anaerobic respiration in yeast through an experiment involving heating the yeast within a glucose solution. The heating process triggers the release of gas, which I will measure as my experimental data. To ensure safety, I will wear protective goggles throughout the experiment. Additionally, I will utilize a […]

Collect all of the apparatus needed for the experiment Fill trough and collection tube with water (Make sure that you are wearing an apron and safety goggles) Set up apparatus as shown on the above diagram Place the pondweed in the test tube and add sodium hydroxide Put lamp in front of the test tube […]

I was provided with a solution of a monobasic (monoprotic) acid. Monoprotic acid is an acid that contains only one hydrogen atom. I was to determine the molarity of the acid by titration with a sodium hydroxide solution, and then use this molarity to calculate the relative formula mass of the acid. An acid is […]

This investigation is to find out what the concentration is of copper (II) sulphate that brings full denaturation of egg albumen. I can find this out by decreasing the concentration of CuSO4 using the serial dilution method to up the diluted state that no longer gets fully denatured. Background Information Egg albumen is a protein […]

My thought on why we watched this film In class In class Is because that It shows one’s ability to delay gratification In order to receive a greater reward. It applies to human adjustment because a person’s ability to be patient and patience Is Important to be able to cope with stress In life. Being […]

One study which looked at lack of control as a cause of stress was Greer and Mammals. The study was a laboratory experiment using a sample of 60 students, who were made to look at photographs of dead car crash victims. The sample was split Into three conditions, each with a varying amount of control. […]

To enhance the amounts of information retrieved, as well as giving focus on important part of notes, students often do highlighting, circling, and underlining. Those three methods are called text-emphasizing. Recent studies have shown that the techniques could help the students to retrieve and store more information compared to students who do not use such […]

Source Evaluation People have come to the conclusion that Southern Hospitality Is well and alive today. We have people traveling all around the country for vacations, visiting family, work, and much more; but do they really know what people of the South are really like if they were to come live here? Southern Hospitality is […]

This is a study of what kind? Census Experiment Voluntary Response Survey Observational Study Matched-Pairs Study Considering a run for public office, an elected official plans to survey voters in his district to determine their level of familiarity with him. Unbiased results would be produced by which survey method from the following options? The politician […]

Participation is in teams from 2 up to 4 students and in order to have a successful performance, individuals must cooperate, collaborate and show adhering, tolerance and responsibility at all times. Rules and specifications Topics and Teachers authorization Although the topics are to be freely chosen, the Science Academy must assure a balance in the […]

The purpose of this experiment is to determine the correlation between the initial height of a tennis ball and the time it takes for it to complete three bounces. The autonomous variable comprises of the various initial heights, ranging from 0.1 m to 2.4 m with an interval of 0.2 m while the dependent variable […]

In addition to recrystallizing acetanilide, the experiment involved trying to recover the crystals with the least impurities. The major laboratory technique used in this lab was hot vacuum filtration, which involved pouring the heated test tube of acetanilide and water through a Buchner funnel that’s on top of an Erlenmeyer flask.Following the recrystallization, the recovery […]
