The materials provide clear structural evidence of connecting the three NGSS dimensions (SEPs, DCIs, CCCs) from unit to unit. E7 states the unit 'is designed to leverage science ideas from previous units and grades' and expects students to engage with practices and CCCs developed across 'the prior 11 units' independently. E12 explicitly tracks DCIs as prior knowledge developed in named earlier units (ETS1.B in the Tsunami, Homemade Heater, and Palm Oil units; ESS2.C/D in Storms), and E9 names CCCs (systems thinking, scale/proportion, patterns) built in earlier 6th-grade units with scaffolding guidance for varied sequencing. E2 confirms the intentional three-dimensional design with font coding to each NGSS dimension, supporting coherent cross-unit dimensional development.
