In "Learning from Bears" (p. 8), you read about how scientists are searching for ways to cure various human ailments by understanding more about how bears hibernate. Complete the activity below to learn more about the number of people in the United States afflicted with the diseases mentioned in the story.
Number of Americans With Diseases Who Could Be Helped by Bears Number of Americans Disease With Disease Kidney Disease 3,700,000 Heart Disease 26,000,000 Gallbladder Disease 25,000,000 Osteoporosis 10,000,000 SOURCES: CENTERS FOR DISEASE CONTROL AND PREVENTION, AMERICAN GASTROENTEROLOGICAL ASSOCIATION, AND NATIONAL INSTITUTE OF ARTHRITIS AND MUSCULOSKELETAL AND SKIN DISEASES.
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.
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?
1. Heart disease affects the largest number of Americans. Kidney disease affects the smallest number of Americans.
2. Gallbladder disease and heart disease both affect roughly the same number of people in the U.S.
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.
