Titanic's Lost Sister

Viewing Ideas


Before Watching

  1. Was Britannic sunk intentionally by a torpedo from a German ship, or did she hit a mine? The evidence for both sides is substantial, but inconclusive. Why is it important to find out? How would historians use this information? What impact might the torpedo theory have if it were proven true? The mine theory? While students are watching the program, have them take notes on the evidence for both theories. Alert students to note possible political consequences if either theory were proven to be true.

After Watching

  1. After viewing, have students think about and choose the theory about how Britannic sank that makes the most sense to them. Poll the class and tally the number of responses for each theory. Ask students to defend their choices using their notes. Because the evidence is inconclusive, students may decide there is not enough information to support either theory. In this case, ask them to suggest what other evidence they would need to decide why Britannic sank.
