INTERNATIONAL SEA URCHIN SCIENCE CENTER

10/13/1999

SITUATION: Below I am suggesting possible lab experiments that might be of environmental interest in a particular country. Hypothetical scientists names are used.

NOTE: This is a real PUSH LAB best reserved for your better students [seniors w/ chemistry background], when you do not have the time or resources to do self created experiments. Individual experiments could be used with younger students who are having difficulty synthesizing the details themselves in an independent experiment. Experiments, Sperm Experiments, & Extended Research

NOTE: Though I have made some attempt to link up a possible experiment with a particular country, this should not be taken to the point of "stereotyping" the problem to just that country. ALL countries face these problems. Pollution is worldwide! The links are to suggestions for "quick and dirty" experiments that can be done in small groups very quickly [assuming teacher sets up ahead of time]. You might break up into groups of 4 students with each group picking a different experiment. Then at the end of the period or the next day, have each group present a short presentation of their findings.

Do the above names look familiar? See Polyglot

All of the above can be expanded into much bigger / longer term experiments.
