10 minutes can go so fast, or drag on to seem like an hour.
I would suggest that, as other have advised, go with 'your passion', what inspires you will be easier to present to inspire others.
Look at the assessment criteria and using a subject that you are passionate about say what you are going to say, say it, repeat it, then say what you have just said. ( sounds gobbledegook, but it's basically introducing the subject, add a bit more info, consolidate what you have said then conclude what you have said) Use different media to communicate, ie: visual, linguistic, active participation etc.
Choose something you are really familiar with, do some research to add weight to your subject ( and add to your own learning) and stick to the objectives of the task.
A WARM WELCOME TO THE FORUM
Have faith in your abilities and just go for it. All your peers will be feeling the same as you and are in the same boat, so relax and enjoy the ride together.
Practice the timescales prior to the presentation. If the criteria is about presentation skills then keep the subject simple/familiar, and concentrate on presentation skills rather than content.
GOOD LUCK.
