I need help doing an introduction for my research paper. Below is something I have tried to work on but I am lost on what else to include. I also have articles we can use to add information to the introduction.
Here is the introduction that I tried to create. In order for the human body to function properly, it needs adequate amounts of sleep. Most adults need 7-9 hours of sleep a night, but this varies significantly across individuals of the same age. (Brain Basics: Understanding Sleep 2022). Sleep is an important aspect of human life as it has a fundamental impact on various body functions. Without sleep, such functions are distorted, which puts the body at great risk.
PLEASE create a good hypothesis, for example, people who had less sleep show problems with pulse rate and heart rate.
Introduction.
The purpose of this section is to illustrate that you have a good grasp of the context of your research question and that your approach is supported by a solid rationale (e.g., It has been previously shown that X is affected by Ycitation, therefore, we set out to determine what specific factors of X alter the expression of Y). A simple way to think of an intro is this: what is already known, what are the gaps in our knowledge, and what you did to fill in those gaps? Select the two or three key concepts related to your experiment and briefly explain them. You should use 6 to 10 succinct sentences to convey this information. You can use multiple paragraphs. In general, a new subject means a new paragraph.
A good introduction naturally leads into a research objective/hypothesis by going from general information to your specific objective (think of an upside-down triangle). In the last 2 or 3 sentences of your introduction, state your rationale and hypothesis, which should portray the relationship you expect to find between the independent and dependent variables. You should end by outlining your basic approach in the experiment.
***** Have a rationale for your hypothesis. The rationale is usually included in the introduction, written in one or two sentences after the background information and before the hypothesis. The rationale must be clearly stated and express the reasoning that led you to the proposal of your specific hypothesis. It should be grounded on your background research from the scientific literature. *****
