One of our book study groups, recently completed Gary Paulsen's Hatchet.  Throughout the book, questions had come up in discussions.  Students compiled a list of some of these lingering questions:  How long can a Cessna 406 fly on a full tank of gas?  How long can a person hold his/her breath under water?  What does a modern day survival pack look like or contain for a single engine plane?  How long would it take for a body to decompose in the water?  What diseases come from drinking contaminated water or wild animal meat?  Are wolves naturally attackers?  How long does it take before a search is called off for a missing person, and who determines the call?  Each student spent time researching his/her particular interests.  It was fun seeing computers, calculators, and maps all in use at the same time.
