Students learn more and retain knowledge longer when they construct
meaning for themselves, rather than having the teacher do it for them.
Investigating personal inquiries, solving problems, and exploring issues
create intimacy with subject content and skills. In addition, satisfying
one's intellectual pursuits is very motivating. We suggest, therefore,
that teachers encourage students to question from multiple perspectives
and to pose problems to solve. Teachers should facilitate students'
constructive responses to issues whenever possible.
The following section of the Giant Squid Web Page curriculum is an
evolving list of possible investigations, problems, and issues associated
with the search for giant squid, and deep-sea research and technology.
Additions from teachers, students, researchers and interested public are
always welcome!
Starting Points for Students' Investigations
- With what would you have to be concerned when working with
electronics and underwater research?
- Why do whales and dolphins beach themselves? What can
humans do to help?
- Why is it that the scientists who watched the Odyssey's first
videotapes saw what looked like footage from the Star Wars
movie in which space ships "jumped to lightspeed"? What
is actually happening in the human eye to cause these blurred
streaks of light?
- How did Adam Frankel determine the depth of whales by
listening to the clicks of whales?
- Why do giant squid have larger and fewer neurons (nerve cells)
instead of smaller and more neurons?
- What do stomach contents tell researchers? Why investigate
them?
- What is it about saltwater that heals open wounds so
quickly?
- How do scientists know where to look for giant squid?
- How does a squid sucker work?
- How do we determine salinity of water?
- Which has broader geographic distribution: marine species that
produce small, but many eggs, or species that produce few, but
large eggs?
- Why would sucker scars on sperm whales be unreliable
evidence for the size of the squid that made the scars?
- How do submarine sonar and radar work?
- Explain the relationship between the success of the Maori
people and the historical way they treated the whales in the
coastal waters off the south island of New Zealand. (Include
their history in both whaling and whale watch tourism.)
What does their experience teach us in our relationship
with [insert a local animal or plant with which the
students would be familiar]?
- What is the muscle structure of the squid's funnel and why
is it built that way?
- What adaptations has the Giant Squid made to its habitat?
- Why do giant squid not get crushed by pressures at the
depths in which it lives? Why do our deep-sea submersibles
not collapse at those depths?
- Why would the sail squid (Histioteuthis) have one large
eye and one small eye?
- What are the advantages of photophores to sea animals that
live in the depths of the ocean?
Starting Points for Student Problem Solving
- How can you keep the ropecam from snagging on fishing gear,
the canyon walls, rock outcroppings, or swimming creatures?
- How do you mount a sonar transducer to the bottom of the
boat's keel such that it:
- extends well below the keel of the boat
- is light-weight, and easily retrievable
- remains rigidly straight against four knots of boat
speed?
- What is the best way to ship sensitive and expensive camera
and research equipment? Specifically, what sort of packing material
will best protect the equipment from extreme temperatures and
rough handling in transit?
- What can be done to make the dangerous descent on the dew and
moss-covered ladders leading to the research vessels
"lurching in the rough ocean below" more safe?
- How do scientists attach a crittercam to a live sperm whale?
Suggested Formats for Class Discussion or Reflective Writing
- Which is more important: scientific truth and discovery, or
animal discomfort? See the
journal
entries about the use of crittercams. (Find the entries for
February 16 and March 12, 14, and 15.) At what point does one
become a higher priority over the other? What are the responsibilities of the
scientist? . . .the local government? . . .the sponsoring
organizations? . . .the public?
- Would you be willing to wear a crittercam so others might learn
from you?
- If you could pick three living species from the ocean to save
for all future generations, which would you pick and why?
