Writing Prompt (Analyzing a Concept Essay)
1. A concept can be an abstract idea (e.g., dating), a phenomenon (e.g., raves), or a process (e.g., parthenogenesis). Successful concept essays are incremental, adding knowledge layer by layer and building information at a pace that is neither so fast as to lose readers nor so slow as to bore them.

2. Review an example of an "Analyzing a Concept" essay, "What It Means to be Creative," by S.I. Hayakawa, in chapter 5 of the textbook. In this essay, the author moves beyond a basic description of the concept of creativity to break down this concept to show the audience the complexity of the creativity.

3. View "The Writing Process" for guidance on the process of writing an essay.
4. Choose a concept to analyze and explain this concept to your classmates.

The item CONCEPT WRITING confuses me because it is a complex item for me.
But after reading your interpretation I came up some ideas related to sleep. I'm not sure whether this is useful to you.

The fudamental layer might be ïźš Sleep is a PHYSIOLOGICAL NEED for human beings (see Maslow's hierarchy of needsïź‰
Also, there is a physical item called SLEEP CYCLE, which includes NREM( Non-rapid Eye Movement) and REM( Rapid Eye Movement). Sleep cycle can be used to improve our sleeping quality.

When it comes to sleep, one concept that cannot be omitted is DREAM.
There is a hypothesis that dreaming is a unique physiological and psychological activity for human.( I have no idea whether this hypothesis has been confirmed or not)

One more thing I could think of is Sigmund Freud's explaination about dream.

Hope this could help you more or less. =D

It is very helpful, thank you! :)
