Motivation
A
valuable emerald and diamond necklace has been lost. The yacht of a
wealthy businesswoman was sailing from Toronto to Cleveland. Her nephew
was onboard so that he could test a new ultra-low frequency observer (UFO). The
UFO could be dropped to the bottom of a lake and transmit data back. The
ship was rammed by another boat and everyone survived because they were wearing
lifejackets. Because of the length of time involved for the boats to sink
surface currents and underwater currents carried the boat far away from the site
of the accident. The UFO is transmitting data nicely which will help find
the wreck and recover a $250,000 necklace which is in the ships
safe.
Many boats have accidents on the Great
Lakes. A lot of people lose their lives because they do not wear their
PFD's (Personal Flotation Device). The simple fact is that anytime anyone
is in a boat a PFD should be worn because of the many different types of boating
accidents that can happen.
Activity
You
are to locate the shipwreck by using the data transmitted by the UFO and
matching up the information with current lake information. Information on
Lake Erie for each lake condition is drawn on an clear overhead of the
Lake. The search areas where all criteria are met are drawn on a final
overhead. A written description of the search area or areas using latitude
and longitude is to be forwarded to a salvage company.
