The shores and oceans around Antarctica are home to about 100 fish species; six seal species, comprising two-thirds of the world's seals; several whale species, including the blue, fin, sei, humpback, sperm and right whales; more than 50 species of birds, including seven penguin species, which make up the largest percentage: the total population of birds breeding on Antarctica is estimated at over 100 million. Current and potential threats to Antarctica include exploitation of wildlife through over-fishing and hunting; an uncontrolled influx of tourists; destruction of the ozone layer and the resulting increase in ultra-violet radiation which could impact the phytoplankton upon which krill feed, and thus affect the food web of the Southern Ocean; and mining of the continent's anticipated mineral wealth (currently restricted by the Antarctic Treaty).
All researchers in Antarctica operate under the terms of the Antarctic Conservation Act, an extension of the Antarctic Treaty. The USAP has especially strict guidelines about "taking" wildlife, which is defined as anything which changes their behavior, from disturbing creatures while filming them to necessary direct contact as when obtaining blood or other physiological samples for research purposes. This Activity puts students in the shoes of researchers who need to get up close and personal with wildlife, without changing natural behavior more than is absolutely required.
Students will collect behavioral data on domestic "wildlife" and "animal behavior", exposing themselves to problems inherent in unobtrusive close observation.
Post the questions below and allow students 2-3 minutes to write their responses. Ask students how accurate these observations are? Are they "scientific?" "Objectively correct?" Why or why not?
Researchers interested in animal behavior train themselves to observe their surroundings with care. With some of the skills and hi-tech tools of James Bond, Agent 007, scientists are environmental spies who use whatever is available-from their senses to computers to satellites-to help them understand the creatures they're studying, without changing their behavior by the very act of studying them. Have students brainstorm real-world examples of such tracking. Some examples might include: the annual Audubon Christmas Bird Count; whale watching; one-way windows in research centers, lab schools and hospitals; hidden cameras in department stores; satellite tracking systems, sonar and radar. Once the "raw data" is collected, researchers organize and work on it until they see meaningful patterns in graphs or statistics, which allow them to make predictions about future behavior which can be tested. If the predictions are confirmed, then researchers can begin to postulate conclusions.
Observing and Recording Animal Behavior
Have students create and compare different types of graphs showing how they use their time (sleeping, reading, eating, studying, watching TV, etc.)
