When constructing a speech, the thing to keep in mind is there are three main parts—an introduction, the body, and the conclusion. In the introduction, you’ll want to have an attention getter that draws the audience in. One way to do this if speaking about Obesity: A Curse is to, perhaps, mention a shocking statistic or even an anecdote. Then (think of a speech like an essay where you’ll have a thesis statement), preface the speech by mentioning the three points you’ll discuss. Then, in the order you mention your three points, discuss the points in one paragraph each for the body mentioning your strongest point last and second strongest first. After that, with your conclusion recap all of the points mentioned and have a call to action for the audience or even a “what if” scenario if obesity is not addressed.
Engineers will often use reverse-engineering to solve problems. For example, by taking things apart to determine an issue, finding a solution and then putting the object back together again. Engineers know how things work, and so they constantly analyse things and discover how they work.
