OBJECTS - An identification and then a discussion about an object and its benefits; i.e., a person, animal, structure, machine.
PROCESS - Instruction, step-by-step, on how something works, is made, or is done; i.e., how to bake a cake, build a birdhouse, use a software program, or fill out a FAFSA.
EVENTS - Information about something that has happened, is happening, or is expected to happen; i.e., the spread of the H1N1 flu virus, the history of the Afghan war, or an explanation of Ponzi schemes.
CONCEPTS - To examine theories, beliefs, or ideas; i.e., explain the theory that TV violence breeds violence or inform your audience about the Koran.
