Then, challenge each student to develop an idea to improve an existing product through the use of an embedded system that allows it to send and receive information. They should compile a list of the products they find and the specific feature that caused them to believe that the product contained an embedded system. Have students research the history of changes in size, speed, power requirements, and use of computers over the past 50 years. Have the class develop a wall chart to demonstrate the rate of progress of their predicted changes. 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.
