Introduction Task Process Resources Evaluation Conclusion
Introduction:
Caffeine is a natural component of chocolate, coffee and tea and is used as an added energy boost in most colas and energy drinks. It is also found in diet pills and over the counter pain relievers and medicines.
“Around 90 percent of Americans consume caffeine every single day in one form or another. More than half of all American adults consume more than 300 milligrams (mg) of caffeine every day, making it America’s most popular drug by far” (Bryant, 2010).

“It's important to know that caffeine is an addictive drug. Among its many actions, it operates using the same mechanisms that amphetamines, cocaine, and heroin use to stimulate the brain. Relatively speaking, caffeine's effects are milder than amphetamines, cocaine and heroin, but it is manipulating the same channels in the brain, and that is one of the things that gives caffeine its addictive qualities. If you feel like you cannot function without it and must consume it every day, then you may be addicted to caffeine” (Bryant, 2010).

Introduction Task Process Resources Evaluation Conclusion
The Task:
What does caffeine really do to your body? Many feel that caffeine is something that helps them get through the day and is not bad for you. Others feel that caffeine is an addictive drug that is very bad for a person to consume. Where do you fit in this spectrum of people?
First: Read about caffeine and its effect on the body, brain, and emotions from the sites listed. Keep a journal of your own caffeine consumption using the provided Journal page in Resources. Reflect on any physical, mental, or emotional changes you notice after 30 minutes and again after 2 hours. Record those also. After the first week, meet with a group of 2 or 3 other students to discuss your findings. Prepare a summary to present to the class using a chart, graph, or model.
Second: research the decaffeination process. Prepare three bullet points on a note card for class discussion on the topic. Put your new knowledge to work by formulating an educated opinion about the health consequences of using caffeine and/or decaffeinated products.

2. Prepare an argument based on your findings for a debate. Make your argument based on the facts that you have found from reliable resources. Please include information from at least three sources.
3. Record your findings along with the resources of the information that you found in a notebook. Prepare a five paragraph paper on the effects of caffeine. Make sure that your paper takes a stand one way or another. Do not have a paper that is in the middle of the road.
4. Include in the paper the research that you found during the task section of this project, and the information related to de-caffeinate products. Also, include items that contain caffeine and their effects on you personally recorded in your Journal.

Introduction Task Process Resources Evaluation Conclusion
The Conclusion:
Caffeine is a product that is easily accessible to a wide range of individuals because it is in a wide variety of products. According to recipes., even decaffeinated products contain caffeine since the process does not remove all traces. Hopefully this assignment has helped you realize how much caffeine you consume on a regular basis.
[pic]
During this process, you have discovered the beneficial and harmful effects of daily caffeine consumption. This should help inform not only yourself, but the others around you about the risks of too much caffeine. You are more informed now about how much caffeine is in popular energy drinks (up to three times more than a cup of coffee). New studies are trying to force energy drink manufacturers to list caffeine content.
What is your opinion? Will this knowledge affect your own habits?
