Welcome, Fuel-Cell Cars! (p. 578)


Step 1. Questions

A hybrid is a mix of two different things. Today, most people drive cars that run on gasoline only. However, a new type of hybrid car has been developed. It is a hybrid because it runs on both gasoline and electricity. How do hybrid cars work?

Write an explanatory essay that describes how gasoline-electric hybrid cars work. To write your essay, you will need to research hybrid cars and gasoline-only cars. Here are some questions to guide your research:
  • How do gasoline-electric hybrid cars work?
  • How do gasoline-only cars work?
  • What are the similarities and differences between hybrid cars and gasoline-only cars?
  • What are the benefits of hybrid cars?
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 gasoline-electric hybrid cars and gasoline-only cars at the library. When you are ready, follow Steps 3 and 4 to write your explanatory 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!
