Out of Sight! (pp. 584–585)


Step 1. Questions

Poets sometimes write about a beautiful sunrise or sunset. Artists and photographers use light to make their pictures visually striking. Clearly, there is something inspiring about changes in light.

Write a descriptive essay about an indoor or outdoor scene. Compare the way this scene looks during the day with the way it appears at night. To write your essay, you will need to research light. Here are some questions to guide your research:
  • What role does light play in sight?
  • What memorable experiences have you had with light? Where did these occurrences take place?
  • How do objects look during the day?
  • How do these same objects look at night?
Are you ready? Begin by visiting the Web sites in Step 2. Look for answers to the questions above, and write down what you learn in the note-taking boxes.

With teacher supervision, you may use search engines to research other Web sites. You also can research light and vision at the library. When you are ready, follow Steps 3 and 4 to write your descriptive essay.



Step 2. Research

Research answers to the questions you were asked in Step 1. Visit these Web sites. Take notes about them on this page, too!
