Mid-Iowa School Improvement Consortium Core:   Science

 

These benchmarks represent the things that every student should know and/or be able to do by the time they complete their elementary and secondary eduation.

 

The first character of each identifier is the grade or course in which the benchmark is typically applied.  For high school classes, the benchmarks are categorized according to course:

LS-Life Science; CH-chemistry; ES-Earth Science; PS-Physical Science; PH-Physics. 

 

Schools teach to these benchmarks in varied order, and not necessarily at the particular grade or course level indicated.
