I used to do presentation workshops and I'll give you a few pointers that will hopefully help.
1. Practice what you want to say tonight, first in front of a mirror, then your family. Doesn't have to be word for word, jus a general outline. Things/info/thoughts change, so be flexable with it.
2. When presenting, remember to breathe. Sounds dumb but you'd be surprised.
3. Make eye contact with different people in the room so you're presenting to the whole class, not just 1 person, or your shoes. So head up
4. Pace yourself, don't rush, don't drag, oh and remember to breathe
Lastly, have fun with it. It's something you enjoy, show it in your presentation.
On a side note, picture everyone with clown noses on. They'll look silly and you won't feel that way
Good luck and let us know how it went!
