Gather your facts for the issue you are addressing for example since I will be talking about world hunger I will do a google search for world hunger facts or statistics.
Next you should open a blank document and find some facts and copy them on to the document But BE AWARE THAT YOU CANT COPY IT EXACTLY UNLESS YOU GIVE CREDIT TO THE SOURCE BY CITING IT easy bib is a free and easy way to do this.
Then you go to screencastomatic.com and download it so you can record what is on the screen.
Now open up a powerpoint so you can put the facts in it.
