It became apparent that though we had spent about six weeks doing experiments and teacher-led investigations at the beginning of the semester, this was woefully inadequate preparation for students to work on their own to come up with similar investigations using the kits.

We began with an investigation into helium, followed by an exploration of dry ice. Here is the description I posted as I began this inquiry.
