Assignment: Do sports drinks really work? Question... How do sports drinks affect muscle reaction time? Hypothesis My hypothesis is if sport drinks are consumed‚ then the reaction rate will improve. Sport drinks provide individuals with the required amount of water‚ carbohydrates and electrolytes (sodium and potassium) which is lost in sweat while exercising. Maintaining adequate electrolyte levels will enable better cell function‚ which is needed for muscle endurance‚ among other bodily capabilities

Question How does chewing gum affect concentration on short term auditory memory tasks? Hypothesis Purpose The purpose of this experiment was to show teachers whether or not they should allow their students to chew gum in class. If teachers take a gander at this experiment then teachers may allow gum for the chance of better test grades. It may also help individuals‚ knowing that chewing gum can improve concentration on short term auditory memory tasks. Materials and Procedures Chewing gum

inside the nucleus. How did Rutherford discover the nucleus? Rutherford conducted the gold foil experiment. To do this he fired alpha particles at a thin sheet of gold foil.He proved that the majority of the mass of an atom was in a small portion‚ meaning that there must be a nucleus holding the protons and neutrons. Why is the gold foil experiment so significant? The significance of the gold foil experiment is that it proved Thomson’s theory of a plum pudding wrong as there isn’t a large amount of mass

damage to 14 % of its forest trees. In this experiment‚ I will find out what consequences acid rain has on the germination and subsequent growth of cress seedlings. I will use cress seedlings‚ which germinate quickly and can grow a few centimetres in a matter of days and sodium metabisulphite‚ which reacts slowly with water to produce sulphur dioxide gas. The seedlings will have to be in an enclosed system so the sulphur dioxide does not escape. The experiment is a simulation trying to model a powerstation

Knowing that calcium helps keep humans healthy and have stronger bones‚ I wanted to experiment how calcium might aid in the growth of lima beans. Background Information: In plant growth‚ calcium effects the metabolic process of other nutrient uptake that is vital for growth of the plant. Calcium also strengthens the cell wall structure (It is an essential part of the cell wall);

How would you devise a social science experiment? In this essay I am going to explain and demonstrate how I would devise a social science experiment‚ I have chosen is ’How are tasks divided up between men and women in the home using married‚ childless couples’. My hypothesis is that; ’although feminism has advanced massively‚ women still take a larger role in the domestic upkeep of the home than their male counterparts regardless of whether one or both subjects work.’ I will outline how the data

In the "Chinese Room Experiment‚" John R. Searle argues against the claim of computers being actual thinking things. Searle argues that even though computers can pass the Turing test does not mean that they could think. With the help of the "Chinese Room Experiment‚" he wanted to establish that computer do not think since human beings influence them. I will explain the reasons for how John Searle’s arguments are against the claim that computers are an actual thinking thing. I’ll first talk about

Gram Stain: The important part of this experiment is being able to determine a bacterium based on its cell wall structure. It also helps indentify if the unknown organism is a Gram positive or Gram negative. This is the initial step that must be taken before any other lab procedure may continue on to ensure the purity is present‚ the arrangement of the cells‚ and the shape the cell has. The staining of the cell starts off with using the primary stain‚ Crystal Violet which is a purple color‚ to begin

MATERIALS AND METHODS This experiment contained two parts‚ a “PART A” consisting of blood pressure measurements‚ and a “PART B” consisting of linear displacement measurements. The equipment used in “PART A” consisted of an OMRON manual sphygmomanometer with a stethoscope attachment as the manual blood pressure meter‚ and a ReliOn Manual Inflation Blood Pressure Monitor model HEM-412CREL as the automated blood pressure meter. The pressure accuracy of the automatic meter was 3 mmHg and held a displayed

Practical 1: Observation of mitosis in garlic root tips Introduction The practical will involve the preparation‚ observation‚ and classification‚ of the various stages of mitosis by observing garlic root tips using a microscope. The study comes under the heading of cytogenetics which is the visual characterisation of genetic material and the study of how that material reacts during the life of the cell. Strictly speaking‚ mitosis is the division of the nucleus into two daughter nuclei that are
