This Scope and Sequence articulates how OpenSciEd’s middle school program is organized into bundles of performance expectations (PEs) used to design a target outcome, how the ideas in each unit build on prior learning, and how the three dimensions of the Next Generation Science Standards (NGSS) are reflected in the PE bundles.
OpenSciEd Scope and Sequence
The OpenSciEd unit map shows each PE bundle as an object in the diagram. Connections between the PEs are shown as arrows. A connection means more than a simple prerequisite relationship. If two PE bundles are connected, e.g., Units 6.2 to 6.4, that means that the unit designed for the second PE bundle (6.4) will involve students in revisiting and discussing what they learned about a particular PE as they work on understanding the phenomenon in this current unit. Students’ new models in 6.4 will require them to revise and extend the prior versions of some PEs from 6.2. The connections between PE bundles may be within a Disciplinary Core Ideas (DCI) strand or between strands.
Focal Science and Engineering Practices
The Focal Science and Engineering Practices (SEPs) are the SEPs on which the unit focuses. These are the SEPs that play a major role in explaining phenomena and solving problems in the unit. Of course, the NGSS SEPs work together to support explaining phenomena and solving problems, so each unit typically brings in other SEPs as needed.
Like the DCIs, these practices are used and built incrementally across units. The symbol “✓✓” indicates a focal practice for which the unit includes explicit supports to further develop elements of the practice. The symbol “✓” indicates a focal practice used in the unit, but for which further development of elements of the practice are not targeted.
Note: These tables represent our current plan. The focal practices may change as each unit is developed.
Focal Crosscutting Concepts
The Focal Crosscutting Concepts (CCCs) are the CCCs on which the unit focuses. These are the CCCs that play a major role explaining the phenomena and solving problems in the unit. Units typically bring in other crosscutting concepts, as appropriate, in addition to these focal ones. Note: These tables represent our current plan. The focal CCCs may change as each unit is developed.
