Have each group discuss this statement and report back listing reasons for and against making a journey into the future. Play a selection of music to the class that gives the impression of music of the future, eg Star Trek, Space Odyssey, The Planets, Computer Music etc. Have students listen with eyes closed and then discuss and share the images evoked. As groups, have students brainstorm.
Groups make oral reports back to the class.
Each group designs their own bulletin board and keeps a media watch for the duration of the unit to identify, collect and display Earth Problems that need to be solved. The place is a small city of about 60,000 people. When completed have group members explain the workings of the machine to the class. Some groups or individuals could design plans of the machine rather than construct it. Explanations of how the machine works should be included with the plans.
