It is in this part of your speech that you tell your audience the essence of your speech. It is suggested that you break down your ideas into a few separate points. You should also start with the most basic or fundamental when delivering the speech. This will help the audience to identify with the content of your speech first and later gradually follow the flow of the speech.
You might want to support your claim with reasons and evidence, and illustrate how these pieces of evidence support the claim. However, you must remember not to spend too long just to illustrate a point. Your audience will definitely ask during the Q&A session if they want to know more.
Do use transitional words and phrases when moving from one part of the speech to the next. Words and phrases such as "first of all", "my next point is", "although" and "finally" serve as cue words to the audience of what to expect next.
