You may wish to find your own organisms or your teacher can supply them for you. Discuss with students the evidence we have that organisms survive the Antarctic winters. Rotifers were plentiful along the shores of Lake Hoare. We know that they survived the winter and reproduce in great numbers. Perhaps one or two students can assume the role of class recorders.
Students can also document the discussion in their lab notebooks.
