Students from grade 4 through 12 will enjoy making decisions based on a situation which was similar to the real-life Apollo 13 crisis. Students must use critical thinking skills to complete this activity. Afterward, the students will be scored on how their thinking matches up with NASA. The activity can be used to show students the many uses of various items and how ranking can be used to determine the usefulness of these items. Students will also see whether working in groups helps or hinders their problem-solving skills.
