1) Choosing a speech topic is the first step in the speechmaking process. Brainstorm ideas for speech topics by posting a list of 5 Things I Know A Lot About and a list of 5 Things I Want to Know More About. 
2) When engaging in discussion with two classmates, consider these questions: Are you knowledgeable in an area in which a classmate has interest? Does a classmate have knowledge of one of your areas of interest? Which topics do you find interesting?
