Graph It

Create a bar graph to show the number of Americans with each disease listed in the chart above. Be sure to give your graph a descriptive title and label the x- and y-axes.

Analyze It

1. Which of the diseases shown in the chart affects the largest number of Americans? The smallest number?

2. Which two diseases affect roughly the same number of people in the U.S.?

3. How many more Americans have gallbladder disease than osteoporosis?

4. If scientists could someday cure all of these diseases through their knowledge of bear hibernation, how many people in total could potentially be helped?

5. If someone you know had any of these diseases, would you want doctors to research bears to help find a cure? Why or why not?

ANSWERS

3. 15,000,000 more Americans have gallbladder disease than osteoporosis.

4. If scientists could someday cure all of these diseases through their knowledge of hibernation, 64,700,000 people could potentially be helped.

5. Answers will vary.
