Weather and Water

Investigation 9

Terms in this table:

• “Investigation” is the number of the investigation
• “Materials Concept Code” is a reference number based on the science concepts and processes listed in the Overview section of the teacher’s manual
• “Materials Concept” is the text of the science concept or processes listed in the teacher’s manual
• “Indicator Code” is a reference number based on Cumulative Progress Indicators from the New Jersey Core Curriculum Content Standards (2002)
• “Framework Indicator Text” is the text of the progress indicator; the conceptual “strand” for the indicator is in parentheses
