Services      The curriculum included two workbooks: a student
workbook and a teacher's guide. These quickly became popular
throughout the US and eventually were used in other countries as
well. As a result of ILE's popularity and use throughout the US,
biologists revised ILE to reflect a more general lake ecology
curriculum. Two new chapters were added to give students a
better understanding of how lakes are formed and how non-native
species can devastate our natural waters.  The improved
Interactive Lake Ecology curriculum is now available for
teachers. The Student Workbook now contains nine chapters and
includes an appendix with vocabulary exercises, experiments, and
a glossary of terms found throughout the text. The corresponding
Teachers' Reference is comprised of all the text in the Student
Workbook, as well as answers to all questions and exercises, and
hints for the experiments.   copyright 2014. State of New
