7th Grade Life Science Curriculum – 2007-08

General Topics:  These topics come from the current textbook (Glencoe Science Life Science).

Learner Objectives:  There are two formats used for the learner objectives.  The first format comes from the State Standards (example 7.S.1.2.3  i.e.:  7 = grade level; S = Standard; 1 = Standard number; 2 = Goal number; 3 = Objective number).  The second format (denoted by an asterisk * ) comes from the original district curriculum, but is not specified in the state standards.

 

These lists of standards, goals, general topics, and learner objectives are guidelines to be used, but are not all inclusive of material covered through the academic year.
