Hiii!!!! It's hard to help with your essay as your plan would be quite unique to you but your presentation should usually include:
- your initial topic ideas and how you narrowed down to your essay title
- the main research and findings you did in your essay
- maybe some of the sources you used and how you found them useful
- also maybe some of the methods you used to plan your project like time managements, source evaluation, etc
- a reflection of how you handled the overall project, usually including what went well and what you could have done better
Hope it goes well, i'm sure you'll smash it!!
