What are some astronomy projects I could do?

I am going to do a science project for a scholarship and I’m not quite sure what I want to do. I really like Astronomy so I think that would be fun. It can be biology, earth science, or astronomy (anything that’s natural). Do you have any suggestions on a project I could do preferably an astronomy one?
