INTRODUCTION/OVERVIEW

PREFACE

These Science Standards are set forth to ensure graduates of the Rapid City Area Schools have the knowledge, skills, and competencies

essential to leading productive, fulfilling, and successful lives as they continue their education, enter the workforce, and assume their

civic responsibilities.

The content students need to acquire at each grade level is stated explicitly in these standards. With student mastery of this content, the

Rapid City Area Schools will be competitive with the best educational systems in other states and nations. The standards are

comprehensive and specific, they are rigorous, and they represent South Dakota‟s commitment to excellence. The standards are firm

but not unyielding; they will be modified in future years to reflect new research and scholarship.

THE PURPOSE OF THIS RAPID CITY AREA SCHOOLS SCIENCE CURRICULUM DOCUMENT

The Rapid City Area Schools Science Curriculum provides a listing of essential core content to be taught and learned. The standards

are designed to guide the planning of instruction and to anchor the assessment of learning from kindergarten through twelfth grade.

Performance descriptors bridge the content standards to assessments of the standards, provide information to teachers and students

regarding student progress toward mastery of the standards, and specify targets for instruction and learning.

IMPORTANT NOTE TO TEACHERS:

Pages 1-13 of this document are a condensed version of the state standards. They

serve as the Middle School Science Curriculum for the Rapid City Area Schools.

You are encouraged to view these pages first. To expand your understanding of

the Rapid City Area Schools Curriculum, see the South Dakota State Standards on

pages 14-63. The indicators in the Rapid City Area Schools Curriculum will help

you locate the corresponding state standards.

Guide to the Numbering and Symbol System

Used in the Document

Standards are coded to cross-reference grades, goals/strands, indicators, and standards.

1.N.1.1.

Grade Goal/Strand Indicator Standard

Grade refers to the grade level at which the standards are to be mastered by students.

Goal or Strand refers to the major area of science (e.g., physical science, life science, earth and space science) this group of standards

address. These strands are coded:

N for Nature of Science

P for Physical Science

L for Life Science

E for Earth and Space Science

S for Science, Technology, Environment, and Society

Indicator refers to the number of the indicator for this goal or strand. Each goal has one or more related indicators that describe key

aspects of the goal.

Standard refers to the number of the grade-level standard for the indicator. Each indicator has one or more grade-level standard(s) that

describes what students will know and be able to do related to the indicator at the specific grade level.

Examples in bold type are directly related and aligned to the level of the standard. These examples represent the level of difficulty

intended in the grade-level standard and possible materials, activities, or sub-skills classroom instructors could use in teaching the

standards.

Grade-level supporting skills represent enabling skills students may need to be taught in order to achieve the standards.

(•) Bullets represent enabling skills to the current grade-level standard students may need to be taught in order to achieve the

standards.

() Checkmarks are enabling skills to higher grade-level standards that are related to current grade-level standards and

thus may be introduced at an earlier time.

Examples that are NOT in bold type are related and aligned to the level of the bullets/supporting skills and checkmarks. These

examples represent the level of difficulty intended in the grade-level standard. They represent some possible materials,

activities, or sub-skills classroom instructors could use in teaching the supporting skills.

New Unpacked Standards are now available on the South Dakota Department of Education Website

http://doe.sd.gov/contentstandards/science/Unpacked/index.asp

These standards are not different from the 2005 content standards, but a more user friendly version. They have been included

in this document in order to further clarify what should be taught and learned at each grade.

Note: Some indicators will not have a corresponding unpacked standard because these topics are not expected to be mastered

at that particular grade level.
