INTERMEDIATE SCIENCE CURRICULUM

8th Grade

Notes to the Teacher

• This document was based on New York State Core Curriculum Grades 5-8 Science and designed for teachers to use in their development of lessons for standards focused instruction.

• Collaboration in lesson design, instructional delivery, assessment development, and resource application is strongly encouraged across and through the grade levels to establish collegiality, consistency, and continuity.

• In a standards-based educational system lesson development should begin with the content and skills (major understandings and performance Objectives) and integrated with assessment. This framework should be used to articulate the design and activities of the lesson.

• This document should be used to design standards focused instruction that would increase students’ understanding and skills in science as well as improve student preparation and performance on state assessments.

• The vocabulary is broken down into two groups. Testable vocabulary is in boldfaced, italicized font, (words that are in the Core curricula, including introductions, and may appear on the ILST). Suggested vocabulary is listed below. If the vocabulary is included in other areas of the Intermediate Core Curriculum, that may be taught in a different grade, the Performance Indicator, Major Understanding or Key Idea is included. Vocabulary that is included in one of the Commencement level core curricula is also indicated. The vocabulary list is not intended to limit teachers to specific vocabulary while planning but rather to provide a list of the minimum vocabulary that students must master to be prepared for the ILST.

CURRICULUM FRAMEWORK

This curriculum should be used as a lesson planning guide/instructional design for teachers.

The Key Ideas

The key ideas are broad, unifying, general statements that represent knowledge within a domain. They represent a thematic or conceptual body of knowledge of what students should know.

The Performance Objectives

The Performance Objectives are derived from the Key Ideas in the Core Curriculum. They are designed to match the Major Understandings and to focus assessment and instructional activities. Performance Objectives provide a general guideline for skill that students must demonstrate to provide evidence of the acquisition of the standard.

The Major Understanding

The Major Understandings are conceptual statements that make up the Content Standards within each Key Idea. They were taken from NYS Core Curriculum and the corresponding identification codes were also adopted. These statements should not be taught verbatim but developed conceptually through instructional activities and cognitive processes.

Suggested Assessments

These are stated as general categories based on the Major Understandings and Performance Objectives. They are designed to assess student understanding and acquisition of the standard. Teachers may develop items that focus on those assessment categories or design their own assessments that measure acquisition of the Major Understandings and Performance Objectives.

Vocabulary

The essential vocabulary was listed in order to acquire the concepts of the Major Understanding. Only vocabulary that is in the Elementary or Intermediate Level Science Core Curricula is testable on the ILST. Students should have a mastery of the required vocabulary and be at the acquaintance or familiarity level with the suggested vocabulary. Visuals should be used to assist in model representations and reinforcement of the terms.

The Suggested Activities

The suggested activities are designed to enhance the understanding of the concepts and prepare students for the assessment. Other activities that support the development of the Major Understanding and Performance Objectives in addition to preparing students for the assessment may also be used.

The Conceptual Question

The Conceptual question is based in the Performance Objectives and Major Understandings. It is conceptual in nature and is designed to focus the lesson. Teachers may elect to develop their own focus or conceptual question based on the Major Understandings and Performance Objectives.
