Reducing our consumption of energy is one step we can take to slow global warming, but many experts think we also need to change how we produce energy. These videos highlights a technological solution -- using coal to generate power, but then capturing the carbon dioxide gas produced before it is released into the atmosphere.

Use the clean, renewable energy of the Sun to power our homes.

As before, if you're working with a partner or in a small group, you will need to collaborate to refine the focus and basic approach of your video and then to write the treatment or create the storyboard.

Use the worksheet provided here to write a text treatment or draw a storyboard for your global warming video.

Be sure to record:

• your main point
• your thoughts about the visual style of your video
• ideas about whom you could or what kinds of visuals you could feature in your video
• the order in which you could present your ideas and information

In your script, you will write out exactly what you want to say and how you want to say it—through narration, dialogue, or interviews, and with visuals. You won't be able to identify all of the visuals you might use, nor will you be able to script the answers of the people you plan to interview. You will have to use your imagination to describe the visuals and audio you hope to capture once you begin videotaping and editing. It is important to think of your script as a working document that will constantly evolve as you move forward with your project.

Before you begin drafting your script, review the sample script to see how it is organized. Note how in each scene, the scriptwriter identifies what viewers would see and hear at any given moment.

Scripts can also contain notes about locations, action, lighting, camera angles and movements, edits, and visual and sound effects. Although the length of scripts will vary, a two-page script generally translates to a video that is about three minutes long—a good length to aim for in this activity.

With this sample script and your treatment as a guide, use the Video Script Worksheet or a computer to write a draft script for your video.
