Have you ever wondred how the speed of an airborn baseball is measured? Its done the same
way that the highway patrol measures the sped of a auto mobile—with a radra gun. A person
holding a radar gun stands behind home plate. The radar gun emits a microwave beams. When the
basebeall moves into this beam, it reflects the beam backto the gun. When the diference inthe
reflected bean and the orignial beam is measured, the miles per hour can be calculateed. Some of

Lesson 105
The Writing Process: Presenting
After completing a piece of writing, you may want to share your work with others. You
can begin thinking about your presentation as early as the prewriting stage when you
define your audience. The nature of your writing will affect how and where you might
present your writing. 
An outlet for presenting your writing to a specific audience is called a 
market
. As a
twelfth-grade student several markets are available to you. Some of these markets may be
related to school, such as school newspapers and classroom presentations. Others might
be in your community, such as local organizations and community newspapers. Other
markets include contests sponsored by magazines or special-interest publications and
newsletters. The Market Guide for Young Writers, available in many libraries, will
provide many ideas for marketing your work. 
To decide how to present your writing, first analyze the piece and pinpoint the audience.
Then search for an outlet that serves that audience. Some outlets, such as classroom
presentations, radio programs, community productions, or speech contests offer a chance
to give oral presentations. In these cases, visual aids may enhance your presentation.
