How to write a greek mythology report?

[questions]

I haven't written a report in awhile, so I was hoping I could get some ideas on what my teacher might expect. At first I was given a chapter titled "Poseidon, Sea deities, Group Divinities, and Monsters." The thought in my mind when I started writing the report was to talk about what the chapter entitles except with more information from other resources. For example at the end of the chapter it doesn't give much information on the monsters so I wrote some specifics like what roles the monsters played in Greek mythology. I also summarized and quoted two stories of particular divinities. Additionally, I wrote about how the divinities were depicted. You can see I just talked about more information on what the chapter entitles. To me it doesn't seem like this is how you write a report.
