Have students input the year, make, model, and other information into the fuel economy website, and calculate the annual cost of gasoline for that car. Ask students to note the city and highway miles per gallons for their cars as well as the greenhouse gas emissions. Discuss car-buying choices consumers could make if they are concerned about rising gas prices and the environment. Have students identify the sources of these fuels, their environmental impact, and the safety issues associated with using liquid hydrogen and gasoline. State your rationale.
Group students with like opinions.
Have each group conduct research to learn more about Japan's whaling industry, the endangerment of whale populations, and the whaling moratorium. Then have each group use its information to produce and present a 1-2 minute television public service announcement presenting either the whalers' or the preservationists' point of view. After the presentations, poll students to see if any have changed their opinions on whaling. Ask your students if they know which of the world's rivers touches more countries than any other. The answer is the Danube.
