Scientific Method Essays

Deoxyribonucleic acid or its commonly known name DNA – is a molecule that contains our genes. It forms part of a chromosome and is only found inside the nucleus of a cell. Our DNA consists of units called nucleotides. Each consists of a 5-carbon sugar, deoxiyribose, a phosphate group and a nitrogenous base – adenine […]

Caffeine is an xanthine alkaloid, that is a known steroid that can promote hypertension and hyperactivity. It is commonly used in drinks that are supposed to “pick you up”. They are caffeine rich and give the drinker a boost of energy. It also has medicinal uses in aspirin and some weight loss drugs. It acts […]

Solar Cells utilize available light and convert it into electrical energy by relying on the photoelectric effect discovered by Alexander Becquerel in 1839. This process doesn’t require chemical reactions, and simply requires a solid state surface to release positive and negative charge carriers upon being exposed to light. Becquerel observed this characteristic while conducting experiments […]

This experiment is to investigate the effects of exercise on heart rate. In my experiment which I will devise I will have independent variables which I will be able to change without affecting the other variables which are the constant variable and the dependant variable which I will measure. Safety will be an important factor […]

Viscosity is a measure of the resistance against the flow of a substance (fluid). The higher the viscosity of a fluid, the less easily it can flow. The viscosity of a fluid can be calculated by using Stroke’s Law, which relates the viscosity of a fluid to the viscous drag (opposing force) and velocity at […]

Our objective is to comprehend osmosis and its significance in the cells of living organisms, such as animals and plants. The experiment will yield proof reinforcing the concept that osmosis entails the transfer of particles from a solution with high concentration to one with lower concentration through a permeable membrane. It is vital to conduct […]

The Americans for Medical Progress site highlights the advantages of animal testing through personal anecdotes illustrating the positive outcomes for both animals and humans. The initial presentation of the site effortlessly captivates with a header depicting a woman affectionately kissing a horse. Additionally, individual contributors have shared uplifting stories of how animal research has aided […]

According to Graft et al. (1), the British Union for the Abolition of Vivisection (BUAV) has claimed that around 100 million animals worldwide are subjected to vivisection, which refers to performing experiments on living animals, every year. For centuries, researchers have conducted vivisection which dates back to the time of Romans. In earlier years, medical […]

More than thirty-five years ago Seligman and his colleagues discovered and reported on two experiments which were to begin an ever-growing field of research, and to fuel continuing debates (Overmeir & Seligman, 1967; Seligman & Maier, 1967). The astonishing feature of these studies was that when dogs were exposed to inescapable shock they adopted behaviour […]

Elisabeth Noelle-Neumann was born in a wealthy Berlin family in 1916. She went on to study newspaper science and history at the University of Berlin and Munich. She received a scholarship from Goebbels (head of the Nazi ministry of propaganda) and did a sojourn at the University of Missouri and Asia. After returning to Berlin […]

An unexplained natural occurrence is yawning. To induce yawning in participants, an experiment was conducted using a video specifically created for this purpose. Three control groups/technical mediums were used to elicit yawns from participants: 1) a video with only visual components, 2) a video with only audio components, and 3) a video with both audio […]

Preliminary work: – We went on a nature walk around the grounds of the school, to see the different varieties of plants and grasses in different areas. We noticed that in the area in front of one of the buildings where the children waited for the coaches, there were a lot less flowering plants, than […]

The question requires us to compare and contrast two different methods used to study cognitive psychology however in order to do so we first need to take a closer look at the goals and objectives of cognitive psychology. After doing so we are going to look the effectiveness of experimental method and Cognitive neuropsychology in […]

Many experiments have been conducted similar to Sternberg’s Memory Search. Some of which supported his claims and others contradicting them. This experiment did both. Supported his claims that the process involved in memory searching was serial not parallel, but the process is self-terminating not exhaustive. However, many other factors that were not considered in this […]

Hypothesis:I predict that penguins huddle to keep warm. This is because when they are all grouped together, the head radiated by those not on the outside will be transferred to the ones next to them, and vice-versa, so almost all heat loss is prevented. The other is insulation. With the penguins all standing next to […]

The volume of water poured into the conical flask was being decided while the uncertainty of the conical flask, calculated from the experimental volume subtracting theoretical volume of water, was being Investigated. -The same conical flask and electronic balance was used throughout the experiment to ensure the results were not to be affected by the […]

The type of acid being investigated is monophonic and the reaction equation between ascorbic acid and sodium hydroxide is unknown. The name and structure of the conjugate base of ascorbic acid is acerbate, with the structure CHICHI-. This investigation focuses on the redo properties of ascorbic acid, including the structure of its oxidized form, Dehydration’s […]

This project was done with the aid of a lot of people. I take this chance to express my gratitude to Mrs. . Handmaid Bit. Mad for the guidance and motivation that contributed tremendously to this project. My thanks and appreciations go to my friends in developing this project too. TITLE Analysis of Vitamin C […]

The lab experiment focuses on the introduction and understanding of mixtures. The objective is to separate a mixture of solids through various methods like evaporation and filtration by utilizing the physical properties of each substance. During the experiment, observations were made, such as the forgetting to cover the top while heating the sand, leading to […]

For this experiment we would observe the offspring that would be produced If we cross breed two heterozygous Individuals, this Is the first generation (Fl The parents of the Fl generation were a dibber cross of ebony body and vestigial winged Drosophila, which are both recessive also known as mutants. Using statistics as a tool […]

Properties of Gases Purpose: The purpose of this lab is to investigate some physical and chemical properties of gases and to use these properties to identify these gases when they are encountered. Hypothesis: This experiment was for observational purposes to learn about the physical and chemical properties of gases, no hypothesis was required In order […]

First recognized as a chemical compound In 1818, hydrogen peroxide Is a clear, colorless llquld most often used for cleaning or disinfectlng(Brltannlca, 2013). Since pure hydrogen peroxide Is unstable, It Is found In stores as an aqueous solution. The chemical formula for hydrogen peroxide Is H202 which means there are two hydrogen atoms and two […]
