Ideas for a How-To Speech Related to League of Legends?

Hi everyone, For a class in school, everybody has to do a how-to speech. For example, "How to make a pizza". I want to do something League of Legends related, and my teacher approved it. Now I have to think of a topic to do, but I can't think of anything cool. I'd really appreciate some help! Below are some facts about me that might be useful and ideas that I've thought of already:

FACTS

1. My main role is support, secondary adc.
2. My current favorite champions are , , , , , and .
3. I'm not in ranked yet.

IDEAS

1. How to play support
2. How to play (insert specific champion here)
3. How to pick a support that synergizes with the adc's pick.

Some words of caution: this will be presented in front of an entire class, with most people unfamiliar with League of Legends. I'd like to try and keep it simple, so I don't have to go too in depth about how the game works. Thank you so much! (and please no trolly ideas :) if you have any questions that would help you brainstorm, please ask!
