What type of speech topic should I pick and why?

The topics that you choose for your speech are based on
the type of speech that you are making. In speech writing as in essay writing, there are
specific purposes that control the choice of topics.

In
speech writing, your basic speech purposes include these four
types:

Informative-to
convey information

       topics might include: types of
fireworks, history of the modern
Olympics

Entertaining-to
amuse

       topics:  Why I get my headaches? The dog ate
my
homework.

Persuasive-to
inform and convince

        topics: Fireworks should be
banned; No drivers' licenses before the age of
18

Commemorative-to
give honor or esteem

        topics: Introducing a famous
person; Giving a biography of someone of importance

You
must know what your purpose is in giving the speech before you can make the right choice
for your speech.
