Good idea.... Because at first, I thought thats what you were going to be doing... reading off the powerpoint, which is why I assumer you were in highschool. That and because it is quite short for an entire project...
But with a well written out speech, you won't be changing slides very often. Only when transitioning into that part of the speech, which I'm hoping will only be every minute or two.
If you'd like, I will review the speech for you. I am actually quite good in the literature department....
