  1. Explain to students that they will be taking all of the information that they have learned about right whales and using it to write a persuasive essay. This could be written as a letter to a government individual or agency in a position to impose regulations that could help protect North Atlantic right whales. Alternatively, they might want to write to a local newspaper so that people in their community are aware of the right whale. In any event, they should select a topic that interests them, identify an appropriate target audience, and develop their argument using the persuasion map. They can use the outline to develop their essay and accompanying PowerPoint presentation.

  4. Explain that they will be "invited" to give a presentation to the government agency or official. They will need to create that presentation and practice it in front of their classmates. The students can use information to develop their presentations. The content of the presentation should be based on the persuasive letter.

How to Use PowerPoint (2016)

PowerPoint allows you to create a presentation made up of a series of slides. These slides can contain text, pictures, or both.

To open the program, click on the PowerPoint icon on the desktop or follow your teacher's instructions.

This is your title slide. Click on either of the text boxes and type the words that you want to add (your title and either a subtitle or your name and class information).

To add another slide, click on Home, then New Slide.

Remember to save your presentation as you work on it. To do this, either click on the Save icon ( ) or click on File, then Save. The default file name will be "Presentation1"—you will want to change that to something that you will remember (e.g., Beth whale talk).

You can add pictures to your slideshow by using the Insert tab, then selecting Clip Art or Picture. Clip Art allows you to choose from images stored in the program. Picture allows you to insert a photo that you have saved on the computer's hard drive. If you choose Clip Art, you can type in a word or words in the search box to find the type of images you want. Once you see an image you want to use, click on it, and it will be inserted into the slide. You can change the size of the image. To do this, click on the image once. Use the mouse to click on one of the small circles in the corner of the image and drag it to make the image smaller or larger.

To see how your presentation will look to the audience, click on "Slide Show" on the menu bar, then "From Beginning." You can use the right arrow, the Enter key, the space bar on the keyboard, or the left mouse button to move forward through the slides. To exit the slideshow, press the Esc key in the top left corner of the keyboard.

Tips for Creating Good Presentations

  1. Use large font sizes. (e.g., 44 for titles, 32 for text in the body of the slide). If you type a lot of words, the text will automatically become smaller.
  2. Don't use too much text on a slide. You should use three to four bulleted points per slide. These are short, simple notes. When you give the presentation, you will explain and provide more information verbally. Try to keep your presentation as simple as possible.
  3. Use a simple font, such as Arial, Tahoma, or Verdana. Fancy fonts are often difficult to read. Use one type of font throughout the presentation. At the most, use one font for the title and another for the body of text.
  4. Use contrasting colors for text and background. You can click on the Design tab to see some options for slide designs.
