Research

Types of things to find:

First hand accounts of people affected by your topic.

Newspaper articles about events related to your topic.

Statistics that both prove and potentially disprove your topic.

Pictures that relate to your topic.  You probably won't use them in your speech, but they might be able to tell you some information.

DON'T ASK GOOGLE QUESTION!!!!!!

    -Internet research is all about keywords

You need to know what it is that you're looking for and then enter those key words.

EX: Instead of asking google "How many attacks have there been on women?" you should google attack stats women (and put in a time range).
