Scientific Method Essays

A highly debated argument in today’s society is animal research and testing. There is much controversy surrounding the issue not only within biology, but general ethics as well. Some people feel that animal research is ethical because it furthers human well-being, as well as provides mechanisms to cure disease. Other people, however, believe animal research […]

The Rolling Choice A pillbug also known as a roly-poly is a small land creature that is often found in many areas around the world. They prefer moist areas often living in soil, under rocks, and dead logs. The pillbug which is an isopod begins its life as a tiny egg and as it grows […]

The issue of animal testing is a globally disputed matter, in which animals are used for experiments and research purposes within laboratories. The aim is to enhance human life or establish potential risks associated with household and cosmetic products. Despite the possible advantages, a significant number of people oppose this practice as it entails ethical […]

1. Why don’t the terms depolarization and action potential mean the same thing? The terms depolarization and action potential differ because are excitable cells that communicate by transmitting electrical impulses that are capable of producing rapid electrical signals and depolarization in the interior surface of the membrane which becomes less negative and the exterior surface […]

INTRO: Cellular respiration is a process that happens in all living eukaryotic cells. What cellular respiration does is turn food often carbohydrates into energy for our bodies. Cellular respiration starts with a carbohydrates sugar called glucose. What it does is alter and break down the six carbon molecule glucose and altering it creating two three […]

Purpose: The pupose of this lab was to make an experimental determination of a molar volume through reaction of the substance shown: Mg(s) + 2HCl(aq) > MgCl(aq) + H(g) Introduction: In this lab, a magnesium ribbon and HCl are combined in a gas measuring tube. When they are combined they form magnesium chloride and Hydrogen […]

Does physical activity have an impact on self-esteem? Abstract This experiment is being conducted to test the correlation between physical activity and self esteem. Two simple questionnaires are going to be used and the participants will all be students at the University of Gloucestershire. Stahle’s work on physical activity and self esteem has encouraged and […]

An Experiment of Adaptation Introduction: Throughout history of time, organisms change in relation to their environment, consequently, adaptation is an essential property of life. This experiment is designed to test the adaptation of Drosophila melanogaster. This kind of insect is also called fruit flies, it has been widely used in scientific research because it has […]

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 […]
