What is the differences between the past simple and past continuous?​

Pick a topic to use for your persuasive lecture. For my example, I'll pick eating healthy foods.  

Think of reasons why you want them to change their eating habits. How do they benefit from this? (Ex: clearer skin, have more  energy to play sports, look and feel healthier, prevent diseases, etc)

Now, think of reasons they would would go against it and find solutions for it.  

Ex:  

If they think they do not like healthy food, mention the wide variety and the targeted audience can see that healthy eating is much more than a couple of vegetables they don't like.

They may also be concerned about not being able to eat the unhealthy foods that they normally enjoy. You can point out that those are still okay if eaten occassionally.
