::OBSERVATION::
Those drinking coffee appear to be more alert in class.
Does drinking coffee improve mental and physical function?
}
}
{
{
Can the effects of coffee alter coordination?

::HYPOTHESIS:: Caffeine improves your mental & physical reaction time to make you faster.

::EXPERIMENT/DATA::
Here we have a simple test of the speed of one’s responses. The purpose of the test is to determine what effect coffee has on a person’s reaction time.

This experiment was conducted by asking an equal number of participants, 5 who had drank coffee, and 5 who hadn’t, to catch a falling ruler when prompted by a buzzer.

Participants were asked to stand with their arms at their sides, fingers 1in apart.
As the buzzer sounded, the ruler was simultaneously dropped. Reaction times were recorded based on the time the ruler was caught.

::COLLECTED DATA:: Drank Coffee | Did Not Drink Coffee | | | ATTEMPTS | Avg | | | ATTEMPTS | Avg: | PARTICIPANT | 1 | .275 .180, .250, .370 | .269 | PARTICIPANT | 1 | .320, .250, .175, .350 | .274 | | 2 | .275, .400, .385, .225 | .321 | | 2 | .350, .300, .285, .285 | .305 | | 3 | .380, .300, .175, .280 | .284 | | 3 | .250, .350, .320 | .317 | | 4 | .220, 275, .200 | .232 | | 4 | .175, .325, .235 | .276 | | 5 | .350, .350, .375 | .358 | | 5 | .250, .350, .350 | 317 |

::CONCLUSION::
After testing the reaction times of individuals who had or had not consumed coffee on that particular morning, we have concluded that there was no significant difference between reaction times. Coffee drinkers had both the fastest and the slowest time recorded at 0.175 sec and .400 sec. The non-coffee drinkers had similar results but stayed within the

    Caffeine Reaction Lab Report

    The experiment did not contain any form of reaction mechanism since no chemical identity had been changed. The lab demonstrates the use of chemical molecular behavior to isolate a particular set of molecules. Caffeine had already existed in the leaf itself but needed to be separated from the other chemicals. Caffeine’s chemical structure is relatively similar to the nucleic acid purine in that they use nitrogen and is bicyclic but lacks an alkene, amine and an amide. Caffeine has a solubility of 67.0 g/100 mL in boiling water but tannins also boil in hot water to form catechin. Catechin cannot react with water but it can with calcium carbonate. The calcium carbonate was added into the reflux beforehand so the catechins can quickly change to form glucose and salts of gallic…

    Experimental sheet for science

    A researcher wanted to test the effect of caffeine on sleep. Fifty students volunteered to participate in the study and signed up for one of two nights. Thirty-three students participated on Tuesday night. They each were given two cups of regular coffee to drink one hour before going to sleep. Seventeen students participated on Wednesday night. They each were given two cups of decaffeinated coffee to drink one hour before going to sleep. Each student was monitored with an EEG (a test that looks at brain function) to record exactly when they fell asleep. Students in the caffeine group took significantly longer to fall asleep. The researcher concluded that caffeine interferes with the ability to fall asleep.…

    How Does Caffeine Affect Behavior?

    Caffeine, the stimulant in coffee, has been called “the most widely used psychoactive substance on Earth .” Synder, Daly and Bruns have recently proposed that caffeine affects behavior by countering the activity in the human brain of a naturally occurring chemical called adenosine. Adenosine normally depresses neuron firing in many areas of the brain. It apparently does this by inhibiting the release of neurotransmitters, chemicals that carry nerve impulses from one neuron to the next. Like many other agents that affect neuron firing, adenosine must first bind to specific receptors on neuronal membranes.…

    Reaction Time Affected by Energy Drink

    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). However, recent research has suggested a synergistic interplay between energy drink constituents, with greater performance benefits conferred by the whole beverage than expected from the caffeine content alone (Marczinski et al., 2011 and Scholey and Kennedy, 2004). For example, Scholey and Kennedy (2004) reported that energy drink consumption improved performance on ‘secondary memory’ and ‘attentional speed’ factors relative to placebo, with no significant improvement in performance following independent caffeine ingestion. However, Scholey and Kennedy (2004) note that independent caffeine effects may have been detected with increased power, particularly in light of the small sample size used in this exploratory study (N = 20).…

    A study performed by Peter J. Rogers observes the effects of caffeine and how withdrawal of caffeine affects alertness and performance. To better understand caffeine and its effects, know that there is a chemical known as adenosine that helps slow down reactions in the body. Caffeine hinders adenosine from latching onto cells. So in hindsight your body has no time to rest if you are always drinking caffeine.…
