need help writing an essay

Hi, I’m in 8th grade and I have to right a big research paper for my Literacy class about September 11th. I have certain key ideas that I need to incorporate into my paper, but I’m about halfway into the outline and out of ideas. Do you have any places that I can find information or do you have any suggestions to give? Also, this paper has to be in MLA format, just if you were wondering.

Thank you!
