This speech is persuasive.Your goal is to explain your position on a question of value or policy, and argue that your position is the one we too should adopt to some degree. That is, you must justify your position on the topic. Your topic must be substantial; i.e. it must be one of cultural/societal importance and significance. You should develop your speech making good use of logic/reasoning, emotional appeals, and credibility. Appropriate topics include: capital punishment is morally wrong/right, gun control is beneficial/detrimental to society, deporting undocumented workers is morally wrong/right, etc.
