(1. Find which city has the fastest growth rate in your county. The office whichhas this information will vary from state to state. Try the records office orthe county information number. The local Chamber of Commerce might have figuresfor a few years. List some cities and their population changes in the past fewyears. Which city had the greatest increase in numbers? What is the growthrate of the closest large city? The greatest percent of increase? Look in analmanac and find the state that is growing at the greatest percent of increase.2. Find out how many classmates have pets. How would you estimate the number ofdogs or cats in your city?3. Look at a map of your state. Is one county of the state more populous thananother? Figure the population density (ratio of number of people to number ofsquare kilometres) of each county. Which is the most dense? Make up a colorcode and color the counties of the state on a map according to their populationdensities.4. Look in an almanac to find which state's population is most dense. Which countryis most dense?5. Use an almanac to find the country from which the greatest number of immigrantscame to the U.S. in a recent year (not in all almanacs). Or, graph the number ofimmigrants to the U.S. for a large number of years and try to explain any changes.6. Graph your school district's enrollment forable. (Call the superintendent's office.)to the city's population growth?the years that information is avail­Is the enrollment growth proportional(7. Find information from state tourist bureaus or your local Chamber of Commerceabout the number of tourists visiting your state or your city. What are the advantagesand disadvantages of tourism?8. Contact the motor vehicles department and ask for the out of state registrationsturned in last year. These figures will give you an approximate number of familiesmoving into your state. Compare them by state of origin. Are the majoritycoming from one state? Graph the results.The following are two examples of mathematics questions based on environmental data.9. In 1975 a whale was killed every 15 minutes on the average. How many were killedthat year?Japan has the largest whaling boats and killed about 210,000 out of the 550,000whales killed from 1960 to 1970 (figures rounded to the nearest 10,000). Whatpercent did they kill?Russia killed about 180,000 in the same period of time. What percent did Japanand Russia kill together? Why do they kill so many whales?The U.S. killed about 2,000. What percent is this?(Data from Project Jonah)(202Permission to use granted by Project Jonah
