Unit Overview/Summary - FOCUS: 

Summary

The unit organizes performance expectations around the theme of seeing objects. Instruction developed from this bundle should always maintain the three-dimensional nature of the standards but recognize that instruction is not limited to the practices and concepts directly linked with any of the unit performance expectations.

Connections between unit Disciplinary Core Ideas (DCIs)  

The concept that seasonal patterns of sunrise and sunset can be observed, described, and predicted (ESS1.B as in 1-ESS1-2) connects to the idea that objects can be seen if they give off their own light or if there is light to illuminate them (PS4.B as in 1-PS4-2). This idea in turn connects to the idea that some materials allow light to pass through them, others allow only some light through, and others block all the light and create a dark shadow on any surface beyond them, where the light cannot reach (PS4.B as in 1-PS4-3).

Unit Science and Engineering Practices (SEPs)

Instruction leading to this unit of PEs will help students build toward proficiency in elements of the practices of planning and carrying out investigations (1- ESS1-2 and 1-PS4-3) and constructing explanations and designing solutions (1-PS4-2). Many other practice elements can be used in instruction.

Unit Crosscutting Concepts (CCCs)

Instruction leading to this unit of PEs will help students build toward proficiency in elements of the crosscutting concepts of Patterns (1-ESS1-2) and Cause and Effect (1-PS4-2 and 1-PS4-3). Many other crosscutting concepts elements can be used in instruction. All instruction should be three-dimensional
