How Can Disappearances Within the Triangle Be Explained?

Your class should first study the locations of missing craft and personnel in the activity titled, “What is the Great Lakes Triangle?” Like scientists, you should examine the data for trends and indicators; in this case you examine concentrations of the disappearances and speculate on their causes. The present investigation is actually three activities that are to be performed by different classroom groups simultaneously through cooperative learning. If time permits, all three activities could be done by the entire class.

The activities treat the wreck of the Edmund Fitzgerald as example of a Great Lakes Triangle tragedy. When all three topics have been considered, there will be a discussion to consider whether the wreck of the Edmund Fitzgerald was an accident resulting from natural causes or whether other supernatural or extraterrestrial forces might be at work (as proposed in Berlitz’ The Bermuda Triangle).


  • Discuss the values of using several data types and sources to solve a science problem.
  • Demonstrate how bathymetric charts are used and constructed.
  • Demonstrate how weather information is mapped and interpreted.
  • Give an example of how scientists use multiple working hypotheses to solve complex problems.
