A dog's sense of smell is many times better than that of a human. As you learned on page 23 of your textbook, dogs can even detect the smell of cancer! But people disagree on whether dogs should be used for cancer research.
Write a persuasive letter to your local newspaper editor sharing your position on using dogs for cancer research. To do so, you will need to research a dog's sense of smell and its ability to pick up the scent of cancer cells. Here are some questions to guide your research:
Why do dogs have such a sharp sense of smell?
Why is it important to research cancer and its treatment?
How are dogs used in cancer research?
Are dogs well-suited for the task? Why or why not?
Are you ready? Begin by visiting the Web sites listed in Step 2. Look for answers to the questions above, and write down what you learn in the note-taking boxes.
You may use search engines to research other Web sites. You also can research sense of smell, dogs, and cancer at the library. When you are ready, follow Steps 3 and 4 to write your persuasive letter.
