will increase the speed of reaction as the greater the surface of the solid reactants‚ the more particles are required to expose and ‘cover’ the capacity of the solid. Increased surface area results in an increased chance of collisions between reactant particles. Since the collisions become more frequent and abundant‚ the rate of reaction increases. Aim The aim of the experiment is to see if a greater surface area of a dissolvable tablet creates a faster or slower reaction Independent Variable

The Effect of Distractions on Reaction Time Purpose: The purpose of this laboratory is to calculate your reaction times and design a procedure to evaluate the effect of reasonable distraction on reaction times. Introduction: Distractions are a part of everyday life‚ but they can become fatal while driving a car. A distraction can be defined as a something that renders a person incapable of behaving or reacting in a normal matter. Such distractions include the use of a cell phone

Effect Of A Sport Drink On Reaction Time Abstract Doing heavy sport such as run marathon or exercise in the gym can produce much sweat. Produce too much sweat could have a significant loss of fluid and electrolytes in the body such as potassium and calcium. This can cause symptoms from fatigue and reduction in exercise performance to more serious conditions such as heat exhaustion or heat stroke (Leong‚ 2007). Drinking water after exercise helps to restore water balance in the body. Drinking

The first reaction time test is the reaction ruler. This test shows the speed of the occipital lobe and the motor cortex of the brain. The faster the reflex the faster the afferent and efferent pathway is. Subjects 1‚ 3 and 5 experienced reaction times that were under the average of 195.167 milliseconds. While Subjects 2‚ 4 and 6 experienced times that were over the average of the population. In general terms it could be said that subjects 1‚3 and 5 have better hand and eye coordination than subjects

was made. Results Reaction time to a second word or non-word is influenced by the previous word or non-word. The null hypothesis stated that all pairs would have the same mean reaction time‚ regardless of whether the first string was a word or non-word. The alternative hypothesis stated that the mean reaction time for word-non-word pairs would be slower than non-word-word pairs‚ which would be equal to the mean reaction time for non-word-non-word pairs.

Introduction Energy drinks are promoted as enhancing behavioural outcomes by reversing fatigue effects and consequently increasing alertness and endurance (Heckman‚ Sherry‚ & de Mejia‚ 2010). Ingredients may include caffeine‚ taurine‚ glucuronolactone‚ sugars‚ and other B vitamins and herbal extracts. Despite the range of constituents‚ researchers generally claim caffeine as the core ingredient responsible for the stimulatory effects of energy drinks (Reissig‚ Strain‚ & Griffiths‚ 2009)

Investigate How Red Bull Energy Drink Affects The Reaction Time of 18-19 Year Old Human Males. DESIGN Introduction Substances that humans intake in food or drink contain various chemicals that affect the normal bodily functions of the consumer. Stimulants are drugs which when absorbed into the body raises physiological or nervous activity. The Red Bull Energy Drink is a stimulant‚ which contains psychoactive ingredients such as taurine‚ glucuronolactone and caffeine. Sportsmen and people requiring

Does concentration affect the speed of chemical reactions? Problem: We are proving that “concentration” (the amount of reactants) is one of the things that can affect the speed of chemical reactions. We are also finding a way to keep the lid on the film canister for the longest period of time. We are using vinegar and water as reactants and changing the concentration every time to see the difference between the rates of reactions speed. Materials: - 1 graduated cylinder - 1 film canister

``Shakespeare Was Not OF An Age But For All Time`` I agree with the statement ``Shakespeare was not for an age but for all time. `` The words of praise probably the most famous ever written about Shakespeare ‚ were penned by Shakespeare`s good friend and follow writer `Ben Johnson`. For the poet and playwright generally considered the greatest ever is also one of the least known of all literary figures. And his works were indeed created for the popular entertainment of his day with little thought
