The beginning of the mission is played on the laserdisc player, while each set of experts looks for pertinent clues for the problem location. Discussion takes place in the expert groups pulling together the evidence from the transmission to collectively decide on a location. Students move back to their cooperative groups. Experts write their opinion on the data sheet before discussion takes place. Groups choosing the correct location will be billed 10,000 dollars and wrong choices cost 20,000 dollars.
Groups write their decision on the data sheet.
Based on the information given in the transmission, cooperative groups rank order the sampling tests they would like to see completed. The teacher plays the test transmission and groups record the information on side two of the data sheet. Steps 13-15 are repeated for groups until everyone has solved and been billed for the number of tests needed. Solutions are played and money is tallied. Groups complete the other three missions following steps 6-17.
