Before Watching
Ask students to imagine that they are living in 2055. If they were excavating
an American dwelling unchanged from 2005, what types of objects would they be
likely to find that might provide evidence about the culture of the time?
(E.g., cars, appliances, TVs, DVDs.) What would they expect to find at a site
where a culture existed without running water, electricity, or automobiles?
Ask students what types of items they would need to bring into a cave if
they were planning to hide there for a long time. What would be the best way to
store food? How would they dispose of waste products? What would they do for
entertainment?
Organize students into two groups. As students watch, have one group record
the technologies used to explore the cave and the other group record the items
found.
After Watching
Have a volunteer from each group share its group's list. What were the
technologies used to explore the cave? (Ground-penetrating radar, endoscopy,
electrical resistivity tomography.) How does each technology work? What items
did archeologists find in the cave? Which items were found with which
technologies? Which items were found through non-technical means?
Scientists used carbon-14 dating to analyze the age of a piece of rope found
in the cave. Have students research how carbon-14 dating works and write a
one-page summary of the process. Ask students to include the maximum age that
can be determined using this technique.
