This has been designed to be a self-directed activity. The questions students learn to ask about objects provide the basis for organized research in both the social sciences and the earth sciences.
Activity #1 is a warmup to activity #2. Activity #2 allows students to test their new knowledge. No answer key has been provided. Students are not being tested on their answer, but on the quality of their argument supporting their answer.
The answer to activity #2: the middle fragment of glass is returned because it is the kick-up of a modern wine bottle. The other two fragments, or kick-ups, were both found at the Cahokia site and date to the French period. They are aproximately the same age: both have the identifying circular imprint of the pontil marker; both glass fragments are thick, reflecting the crude materials that were used by the French to make wine bottles; both glass fragments have a pearly patina, which suggests they have been in the ground a long time.
