I have to write an essay on 9/11 due Friday, what are some topics I could talk about?

The reason you are having difficulty is the same reason most high school and college students have difficulty writing papers and preparing speeches/presentations... remember this for future assignments:

You shouldn’t even TRY to write until you have first done the research... You cannot write about a topic unless, and until, you have LEARNED something about the topic!

Go to your school library, or research online... and find 3-5 academically-acceptable resources. If you don’t know what “academically-acceptable” means, you need to research THAT before you begin. (Concentrate on primary resources, non-fiction and biographical books, and information obtained from “.edu” sources.)

Do AT LEAST 2 hours of research - AFTER you find your references (searching for references does not count) - for each 500 words you will be writing. Take notes as you go, especially noting the main ideas that are repeated in more than one reference.

Choose one of these main ideas, and form an outline with additional information that supports that idea.

Then...and ONLY then... begin to write.

lingering effects on first responders

Why the USA is so hated.

how it was so horrible they did that

The horror of being in one of those planes knowing you were going to die.

u could write about the New York world trade canter attacks 9/11/2001

Maybe something about how it affected (and to some degree still affects) New York City, the US in general, and all of North America.

Student visa overstay issues.

You should ask the 9/11 truther troll about his University of Alaska Fairbanks report.
