Let's hear some of your hypotheses. Try to have students who seldom respond get that opportunity here. Make notes on a clear transparency or chalkboard. Later, as you have time, ask for justifications of some of the hypotheses. You want to communicate the hypothesis should be made from some evidence, for some reason, although the hypothesis is yet to be proved.
Researchers often have difficulty separating their culture from the culture they are studying.
Suppose an archaeologist from a future culture that built many temples and other large buildings as part of their religion studied the remains of our culture. Church buildings would be found, but other large, lavish buildings might be assumed to be churches or religious buildings. Maybe even a gymnasium or hockey arena would be catalogued as a temple. Perhaps some of our finest libraries would also be considered religious buildings. Archaeologists and anthropologists have a difficult, but exciting job.
