The materials show intentional, broad coverage of grade-band Life Sciences DCIs across multiple units. LS1.B (reproduction/growth) appears in selective breeding and plant reproductive structures [E1], LS3.A/LS3.B (inheritance and variation) via MS-LS3-1 and MS-LS3-2 [E2][E12], and LS4 (natural selection, common ancestry) via MS-LS4-1, MS-LS4-2, MS-LS4-3, MS-LS4-5 [E8][E2], plus LS2 ecosystem DCIs in grade 7 (MS-LS2-4, MS-LS2-5) [E10]. PEs are explicitly named and tied to phenomena and assessment rubrics (redwood growth, MS-LS1-5) [E3][E6][E9], demonstrating the materials are structurally designed to incorporate the full set of grade-appropriate LS core ideas.
