1. Lost on the moon

2. . Lost on the moon – 1 Consider yourself a member of a spaceship crew.
Your spacecraft was originally scheduled to rendezvous with a mother ship on the lighted surface of the moon.
Due to an energy failure, however, it was necessary for you and your crew to crash-land some 200 miles from the mother ship.
In landing, much of the equipment was damaged beyond use and several of the crew were injured

3. Lost on the moon – 2
Fifteen (15) items of equipment were left intact and undamaged during the crash landing.
And, since it is necessary for you to reach the mother ship as quickly as possible if you are to survive, some of the undamaged equipment must be selected for the 200-mile trek which lies ahead.

4. Lost on the moon – 3 Task 1: Take “Individual worksheet”.
Your task is to rank the order of all 15 items in terms of their importance and utility in ensuring your survival on the journey to the mother ship.
Place the number 1 by the most important item, and number 15 next to the least important item.
Consider at all time what you know about moon conditions in making your selections.
Please work individually without consulting other crew-members.
Record time needed to complete your work.

5. Lost on the moon – 4
Task 2:
Gather group together.
Take “Team worksheet”.
Repeat task 1 brainstorming now in the team.
As a group, you must reach consensus regarding the relative importance of these items in your mission to reach help at the mother ship.

6. Lost on the moon – 4
Task 3:
Compare the group result with your individual ranking.
Copy the team ranks into your individual worksheet.
Task 4:
Record in the worksheets NASA’s experts answers on the same test (see next slide)
