Investigating the effect of discomfort on reaction time Purpose and method The purpose of this investigation was to investigate the effect of discomfort on reaction time in humans‚ measured by dropping a ruler into a subject’s hand. Discomfort was caused by a bowl of ice. Background information Information is carried from the sensory receptors to the central nervous system and back the to effectors by means of nerves. When a number of different processes are involved (a situation informally

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

Concentration Camps in Vienna The Auschwitz concentration camp complex was the largest of its kind established by the Nazi regime. It included three main camps‚ all of which deployed incarcerated prisoners at forced labor. One of them also functioned for an extended period as a killing center. The camps were located approximately 37 miles west of Krakow‚ near the prewar German-Polish border in Upper Silesia‚ an area that Nazi Germany annexed in 1939 after invading and conquering Poland. The SS authorities

Abstract: This project looks at how the temperature of an experiment can affect its reaction time. The purpose of this experiment is to determine if dissolving reactions are affected by waters temperature. I believe that if the H2O temperature increases‚ then the Alka-Seltzer tablet will dissolve faster because the hot water molecules will move faster colliding with the tablet particles. Water will be the independent variable due to the fact is will always stay in its same form throughout the

CONCENTRATION - The Tunnel Vision Of Mind. Concentration is the art of being focused at what one is doing without permitting any form of hindrance. It is an essential skill that every individual develops as he/she grows up. It has to be developed by one’s own effort and cannot be injected into one’s mind. Of course‚ at times‚ people may guide them as to how to gain concentration‚ but the key to having full concentration is in our hands.

During all this‚ concentration camps were being made. A concentration camp is a place where large numbers of people‚ especially political prisoners or persecuted members of a minority‚ are imprisoned in a small area with inadequate facilities‚ sometimes to provide forced labor or to await mass execution. Many of these concentration camps later became death camps for Jews. One of the most infamous concentration camps was Auschwitz because it was the largest of all concentration camps. In these

LAB 1: What temperature does the enzyme actually work properly in? (Hypothesis) If the temperature is below 40 but above 20‚ then the liver will show bubbles. If the temperature is raised higher than the optimum temperature‚ then an extreme decline in enzyme activity would occur following by the quick denaturing of the enzyme‚ rendering it is permanently useless. Also about 37°C is body temperature. The liver that was at 25°C had a huge amount of bubbles (a 4 on the scale) and the 0°C

sulfate solution of the electrolyte. In order for a chemical reaction to take place‚ the reactants must collide. The collision between the molecules in a chemical reaction provides the kinetic energy needed to break the necessary bonds so that new bonds can be formed. Thus‚ increasing the concentration of the anode‚ zinc sulfate‚ will increases the rate of reaction for oxidation because there are more zinc ions in the new concentration‚ which would also increase the collision between molecules.
