For our health class, we have a class debate and my group will be debating the cons to animal experimentation so we are saying its bad. I'm in charge of the opener and the introduction for our group. Ive researched a lot and have come up with facts, but i'm having trouble to start the debate without throwing out any of the good arguments and still grasp the audience's attention and their support. The audience is the students and we can't use pictures.
