Standards

Idea Sheets are cross-referenced to subjects listed in the Common Core, Next Generation Science Standards, and California Content Standards.

  • Plan & conduct an investigation to determine the effect of placing objects made with different materials in the path of a beam of light. ||Next Generation Science Standards||Grade 1||Physical Science||Waves and their Applications in Technologies for Information Transfer

  • Analyze data obtained from testing different materials to determine which materials have the properties that are best suited for an intended purpose.||Next Generation Science Standards||Grade 2||Physical Science||Matter and its Interactions
  • Develop a model to describe that light reflecting from objects and entering the eye allows objects to be seen.||Next Generation Science Standards||Grade 4||Physical Science||Waves and their Applications in Technologies for Information Transfer
  • Develop & use a model to describe that waves are reflected, absorbed, or transmitted through various materials. [Both light & mechanical waves. ] ||Next Generation Science Standards||Middle School||Physical Science||Waves and their Applications in Technologies for Information Transfer
