    For someone who is new to the subject, the semantics of what constitutes a theory or a hypothesis can both be too much detail and ... For those with a litigator's sense of detail though, it may be interesting to debate whether "continental drift" constitutes a theory? If so, that implies that ideas can be theories even when they have been disproven or more conjecture than we give to plate tectonics. Fish

  • Questions for thought
    This part of the standards concentrates on a particular set of dynamic processes: Plate tectonics. Students will need to recall or review items from other areas of science science and math.

    1. Was continental drift a "theory"?
      Is it a force, theory, object, concept?
    2. Topics for debate Is continental drift a theory?
