I wrote about Roblox because I play it every day. I  took pictures from my i Pad and sent it to my drive. I tried to look for books about Roblox but I could not find any.  I put in a few text structures for example pros and cons, compare and contrast, text features, subtitles and glossary. I also learned that you could put in a mini story. My mini story is about Wizard Tycoon. I had to talk like an expert or I would not be writing about Roblox. Also instead of just writing facts you could add some ideas. I also used I but then Mrs. Degrazia told me to change it. I learned to connect my chapters to have a logical sequence. Also your pictures need to match your words. Remember this is an expert book you will learn something. Hope your walking away thinking about something on Roblox.
