By using the same plastic inside, you can inexpensively create a shuttle flight deck which is realistic in size and appearance. Provide plenty of ventilation. Tape in pieces of clear plastic for windows. You can also use desks and tables as supports for computer and video tape monitors so that you can recreate the electronics of the simulator as well. Another simulated space activity using the above techniques is to have students design and build a space station using large cardboard boxes and tubes.
Large tubes are also available from carpeting stores.
As always, be sure you provide adequate ventilation at all points. Of course, all of these techniques can be applied to the construction of moon vehicles, moon bases, interstellar exploration ships, and bases on other planets. Our space shuttle simulator has been a Mars voyager and an interplanetary explorer as well as a space shuttle.
