The Power of Concentration By Remez Sasson When I was a child‚ I saw how a magnifying glass could burn a piece of paper‚ when the rays of the sun were focused through it. The fire could start only when the sun’s rays were concentrated to a small point. When the magnifying glass was moved too far away or too close to the paper‚ the rays were not focused enough and nothing happened. This experience describes vividly the power of concentration. This power can be described as focused attention. It

What happens after death? My current opinion At this point in time‚ I think that when you die‚ the body decomposes and rots away along with the brain‚ thoughts‚ experiences ect… At the point of death‚ energy leaves your body which previously granted you consciousness and the ability to carry out the life processes. This is the soul‚ when the soul exits the body; it is judged by the ‘higher power’ and then either sent to heaven or sent back to Earth as a punishment. It takes on another body generally

In class we decided that the rate of a reaction increases when there are more collisions or when the activation energy is reduced. We then determined that there were four ways to increase the reaction rate: increase temperature‚ add a catalyst‚ increase surface area‚ and increase the concentration of reactants. The objective of this lab was to experimentally show how temperature and surface area impact the rate of reaction‚ so only two of these methods were tested. The evidence indicates that increasing

Name ____________________________ Date ____________ THE EFFECT OF CONCENTRATION ON THE RATE OF DIFFUSION PURPOSE: This experiment will explore the concentration gradient by measuring the rate of diffusion in a number of theoretical cells. The objectives for this lab are: (1) To define concentration gradient‚ (2) To explain experimental data concerning different concentration gradients‚ (3) To complete a data table and prepare a graph to illustrate the data‚ and (4) To apply information from

Plan a procedure that will allow you to compare quantitavely the glucose concentration in fresh samples of orange‚ lemon and grapefruit juice. Aim: The aim of this investigation is to produce a set of data which will enable comparison of the glucose concentrations of orange‚ lemon and grapefruit juice. Research: Benedict’s Reagent is a mixture of sodium compounds and copper sulphate. The copper ions are reduced by fructose (a reducing sugar) to form copper oxide‚ thus turning it from blue

What Would Happen If Half Of The Canadians Died? By Steffi Bael Have you ever wondered what would happen if half of the Canadians died? Well in the next few paragraphs I will be explaining what would happen. Hypothetically speaking‚ if half of the population in whole Canada vanished‚ definitely a severe suffering of economy would happen. We are all independent on our resources for living‚ natural and especially the human

effect of substrate concentration on the rate of enzyme activity of Catalase Aim To investigate the effect of substrate concentration (manipulated by increasing concentration of hydrogen peroxide) on the rate of enzyme activity of catalase‚ produced by liver cells‚ on the decomposition of hydrogen peroxide. Introduction Enzymes are biological catalysts that increase the rates of reactions. In an enzyme-catalyzed reaction‚ the substrate binds to the active site and forms enzyme-substrate complex

Based off the results from this lab the student was able to determine and have an overall better understanding of the variables that affect the rate of photosynthesis in a plant. The first variable the student tested in the lab was 30cm of light with CO2 present. The student started this trial with all 10-leaf disks and timed how many leaf disks came up every minute for 15 minutes. One minute into the trial and the student recorded that no leaf disks had yet to rise to the top of the solution. At

determine the Vitamin C in a solution of known concentration. Observations of the Vitamin C sample and the amount found on the label was recorded. A tared piece of weighing paper was used to weigh 0.27 g of Vitamin C. The Vitamin C was then transferred to a clean 50 mL volumetric flask. The flask was filled to the mark with distilled water and covered with Parafilm. It was then inverted to mix.

“Why is the Initial Consultation so important” What factors will an ethical therapist cover at this time? During this essay I will be discussing ethics and what ethical issues the therapist faces Relating to the initial consultation‚ what an initial consultation is and why it is important. What the process is‚ what happens at the initial consultation and how the therapist will gather and‚ what benefits and what contra indications there are for having an initial consultation. The word “Ethics”
