OpenSciEd 6-8 Science

The materials consistently connect their anchoring phenomena and problems to named grade-band (MS-level) DCIs. E2 ties rising temperatures to ESS3.A, ESS3.C, ESS3.D plus PS1.B and PS3.A; E9 links the changing-precipitation phenomenon to MS-ESS3-1 and the carbon/water system; E5 maps the ecosystem problem to MS-LS2 and MS-ETS1 PEs with focal DCIs; E7/E8/E11 explicitly identify which DCIs (ESS2.C, ESS2.D, ESS3.D) are developed or activated to explain the phenomenon. This structural, scope-and-sequence-level alignment of phenomena to grade-band DCIs across multiple units satisfies all required components.

The materials structurally embed three-dimensional integration as a core design principle: every lesson includes one or more lesson-level performance expectations (LLPEs) explicitly built to combine science and engineering practices, disciplinary core ideas, and crosscutting concepts, with font coding indicating each dimension's alignment [E1][E2][E3][E4][E5][E6]. This design is consistent across all grade bands (6, 7, and 8) and multiple units. E12 shows the integration operationalized in a real assessment, where LLPEs are described as 'an integration of elements from the three dimensions' to look for 'working together' in student explanations. This consistent, intentional integration in student learning opportunities meets all required components.

Materials consistently present phenomena as directly as possible through firsthand observation and authentic media rather than secondhand description: students examine actual candy ingredients and identify palm oil hands-on [E1], view real post-Superstorm Sandy images and explore an actual flameless MRE heater in action [E3], and watch authentic news video clips like 'The Town Without Water' from Porterville, CA to record noticings and wonderings [E5][E7]. The design further maximizes directness by localizing phenomena to students' own communities and bringing in local water bodies, schoolyards, and student-collected images [E4][E6][E8]. This structural pattern across units shows the materials intentionally give students the most direct access to phenomena available.

The materials show consistent, intentional support for three-dimensional sensemaking: every LLPE is explicitly designed to combine SEPs, DCIs, and CCCs with font-coded dimension alignment [E2], and assessments are built around the integration of all three dimensions working together across student explanations and models [E7][E9][E10]. Sensemaking is anchored in phenomena (bath bomb, sea turtle incubator) where students develop and revise models that integrate macroscopic/microscopic reasoning and apply CCCs like patterns and cause/effect [E3][E5][E6], and tools like the Progress Tracker and peer feedback sustain student-driven reasoning over time [E1][E12]. This structural evidence across multiple grade-7 and grade-8 units demonstrates the materials consistently support meaningful three-dimensional sensemaking.

Lesson-level tables explicitly pair each lesson with a 'Phenomena or Design Problem' column driving the learning (E1, E4, E9, E12), and the three dimensions are named throughout: DCIs (ESS3.A, ESS3.C, ESS3.D in E2), SEPs (analyzing/interpreting data, developing/using models, constructing explanations, asking questions, using mathematics in E6, E7, E8), and CCCs (Scale/Proportion/Quantity, Stability and Change in E7, E8). The structural design consistently embeds all three dimensions into individual lesson learning opportunities across both grade-6 and grade-7 units (E10, E11). This consistent presence across learning sequences meets the indicator's bar.

The materials are explicitly designed to elicit direct, observable evidence of three-dimensional learning. Every lesson uses Lesson-Level Performance Expectations (LLPEs) structured to combine SEPs, DCIs, and CCCs, with fonts indicating each dimension's alignment [E2][E3][E4], and assessment guidance routinely names 'when to check for understanding' and 'what to look for/listen for' tied to specific observable student products and discussions [E7][E9][E11]. Answer keys and rubrics instruct teachers to look for 'these three aspects working together' across student explanations and models [E8][E10][E12], and pre-assessments target student 'fluency in three-dimensional learning' [E5][E6]. This structural evidence across multiple grades and units shows the design intentionally generates direct, observable 3D evidence.

The materials intentionally leverage both prior science knowledge and personal/community experiences related to the anchoring phenomena. Teacher guidance explicitly identifies prior-unit and prior-grade knowledge to activate—e.g., water cycling from 5th grade and the Storms Unit [E2][E5][E6], energy transfer from the Cup Design Unit [E10], and DCIs about waves from 4th grade for the tsunami anchor [E8][E12]. The materials also deliberately draw on students' lived experiences, prompting them to share family/community water stories and personal experiences with natural hazards [E3][E9][E11], with named guidance on how and when to elicit (and not over-elicit) these ideas [E3][E12]. This shows intentional, structured leveraging of prior knowledge AND experiences across both grade-band units.

OpenSciEd's lesson-level performance expectations (LLPEs) are explicitly designed as three-dimensional, integrating SEPs, DCIs, and CCCs, with font-coded alignment to each NGSS dimension [E2, E6, E7]. Each lesson includes mapped assessment opportunities and 'When to check for understanding'/'What to look for' guidance that elicit observable evidence (student handouts, models, discussions) [E8, E9, E10], and answer keys instruct teachers to look for 'these three aspects working together across the students' explanations' [E11]. This structural design across multiple grades/units shows materials consistently elicit direct, observable evidence of three-dimensional learning, supporting all required components.

The materials show anchoring phenomena/problems embedded across multi-lesson storylines—hail/precipitation driving Unit 6.3 with re-anchoring in Lesson 14 [E7][E11], the bath-bomb phenomenon launching Unit 7.1 [E10], M'Kenna's digestive symptoms structuring Unit 7.3 [E12], and the community resilience plan in grade-7 Earth's Resources [E1][E8]. Each lesson includes Lesson-Level Performance Expectations explicitly designed as three-dimensional learning that combine SEPs, DCIs, and CCCs [E3][E4][E8][E10], and Driving Question Boards plus lesson-by-lesson phenomena tables [E11][E12] show students using and building all three dimensions across lessons to explain the phenomena [E5][E9]. This structural evidence supports all required components of the indicator.

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.

The evidence shows an intentional sequence where student tasks build in sophistication across the unit: in Lesson 2 students 'construct their first written argument with scaffolding' as a formative checkpoint [E2], progress to predictive arguments around competing claims in Lesson 5 [E3], then to revised evidence-based arguments evaluating alternate arguments in Lesson 9 [E6], culminating in an independent summative argument on notebook paper in Lesson 10 [E4]. The numbered lesson-level performance expectations (Lessons 1, 2, 3, 5, 6, 9, 10, 11) with escalating SEPs—from developing initial models [E9][E11] to constructing explanations using molecular models to predict outcomes [E7]—demonstrate a designed, increasing-complexity arc. The teacher guide explicitly frames early tasks as scaffolded/formative and later ones as summative, confirming the intentional progression [E10][E2][E4].

The materials systematically present DCIs, SEPs, and CCCs through dedicated 'Focal Disciplinary Core Ideas / Focal Science and Engineering Practices / Focal Crosscutting Concepts' boxes in each unit, with accurate standards alignment (e.g., MS-ESS2-4 water cycling, MS-PS2-3 electric/magnetic forces, ESS1.A 'The Universe and Its Stars,' PS2.B fields acting at a distance) [E1][E3][E5][E8]. The science content is stated correctly throughout — e.g., energy transfer tracking (CCC 5.4), particle motion/state changes (MS-PS1-4), and patterns of apparent solar/lunar/star motion [E5][E10] — and assessment keys/rubrics integrate the three dimensions accurately as LLPEs [E4][E7][E9]. No scientific inaccuracies appear in the retrieved evidence, and the structural design intentionally develops each dimension correctly, supporting a full award.

The materials show deliberate, explicit boundary-setting to keep DCIs within the grade band, the core requirement of this indicator. The 'Where we are going / Where we are not going' design feature explicitly flags out-of-band content as off-limits: stars and stellar evolution are named as high school and not modeled or explained [E3], the complex genetic basis of disease is identified as 'well above grade band' and avoided [E7], and base pairs/nucleotide sequencing are reserved for high school with mutation work intentionally limited to phenotype-level effects [E8]. The materials also carefully calibrate terminology to prior grade-band DCIs (the elementary definition of 'species' from LS4.B) rather than overreaching [E4], demonstrating intentional alignment to grade-band DCIs throughout.

The materials clearly incorporate Physical Sciences DCIs and performance expectations across grade bands. Grade 8 'Earth in Space' develops MS-PS2-4 gravitational interactions [E1, E6] and MS-PS4-2/PS4.B electromagnetic radiation and wave models of light for brightness, color, and reflection/absorption/transmission [E2, E8, E10, E12]. Grade 6 'Weather, Climate & Water Cycling' builds toward MS-PS1-4 particle motion and thermal energy with an explicit particle model of matter and energy transfer/convection [E4, E8, E9]. This structural alignment—named PS performance expectations, DCIs, and modeling sequences embedded in phenomena-driven units—supports all required components of the indicator.

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.

The materials provide robust, intentional development of grade-band Earth and Space Science DCIs across multiple units. The grade-8 'Earth in Space' unit builds toward MS-ESS1-1, MS-ESS1-2, and MS-ESS1-3 (Earth-Sun-Moon system patterns, gravity-driven motion, and scale properties of the solar system) with sequenced lessons and explicit DCI/PE alignment [E4][E5][E9][E10], while the grade-6 'Rock Cycling & Plate Tectonics' unit develops MS-ESS1-4, MS-ESS2-2, and MS-ESS2-3 (geologic time scale, surface-changing processes, plate motion evidence) [E7][E8][E11]. Lessons engage ESS1.C and connected DCIs through models, data analysis, and explanation-building across appropriate timescales [E1][E3][E6], showing structural evidence the program intentionally supports ESS core ideas across the grade band. Coverage spans both ESS1 (Earth's place in the universe/history) and ESS2 (Earth's systems) strands, supporting all required components.

The materials show intentional, structural ETS integration across multiple grade levels with explicit "Connections to Engineering, Technology and Applications of Science" sections in each unit ([E1], [E4], [E6]) that name the ETS elements developed and explain how. Students engage in authentic engineering design—identifying criteria and constraints, evaluating solutions and tradeoffs, and accounting for stakeholders ([E2], [E3], [E6], [E11])—with explicit alignment to engineering PEs MS-ETS1-1 and MS-ETS1-2 ([E8]) and a stated engineering design focus in the scope ([E9]). Materials also build on prior engineering experience across units ([E12]) and connect science and technology advancement to applications ([E5], [E10]), satisfying all required components.

Materials intentionally and repeatedly engage students in both asking questions and defining problems across grade-6 and grade-7 units, with explicit SEP alignment and teacher-guide design support. Students develop open-ended how/why questions for a Driving Question Board (E2, E11), use a dedicated Asking Question Tool to distinguish open/closed questions and identify question purpose (E4), and receive causal/systems question stems (E5). Problem-defining is well supported: students define design problems for food-resource and palm-farm systems with cause-effect framing (E6, E7), and assessment rubrics evaluate asking questions and challenging plans against criteria (E8), with recurring 'Supporting Students in Engaging in Asking Questions and Defining Problems' callouts (E1, E3). All required components are structurally present and standards-aligned.

The materials systematically engage students in the Developing and Using Models practice across multiple grades and lessons. Students develop initial individual models, compare with partners, and build class consensus models (E2, E6, E12), then revise them with new data over time (E10, E1). The practice is explicitly tagged to lessons and aligned to NGSS modeling PEs such as MS-PS1-4 and MS-ESS2-4/2-6 (E5, E7, E9), and the materials intentionally develop sophistication including identifying the limitations of a model (E4) and distinguishing diagrams as a model type (E8). Teacher guidance provides concrete look-fors on students' causal modeling (E3, E5, E11), confirming full structural support for this indicator.

The evidence robustly supports SEP3 across multiple lessons: students collaboratively plan AND carry out investigations in a closed system to determine where bath bomb gas comes from [E2][E3][E4], including identifying data, tools, and measurements needed [E3][E5][E7]. Materials guide students in planning what data to collect and how to organize it [E5][E12], carrying out investigations in small groups [E7], and the assessment explicitly evaluates students' ability to plan and carry out an investigation with calcium carbonate and malic acid, with an individual planning option [E6][E9]. This shows intentional, structural support for the full practice (both planning and carrying out, collaboratively and individually).

Structural evidence shows the materials intentionally and repeatedly engage students in analyzing and interpreting data across grades 6-8, with dedicated lesson segments (e.g., '4 · ANALYZE DATA FROM LIGHT AND TEMPERATURE INVESTIGATION' [E1], '3 · ANALYZE HAIL FREQUENCY MAP DATA' [E12], 'MAKE SENSE OF DATA' [E8]). Students work with real data tables ([E4]), construct and interpret graphs, trend lines, and best-fit lines ([E3][E9][E10]), and use structured sensemaking strategies like WIS/WIM and the I2 strategy ([E2][E3]). The design is explicitly framed as a learning progression toward data-analysis fluency anchored to NGSS Appendix F elements and the K-12 Framework ([E5][E10][E11]), with recurring teacher 'SUPPORTING STUDENTS IN ENGAGING IN ANALYZING AND INTERPRETING DATA' callouts. This satisfies all required components of the indicator.

Evidence shows the materials intentionally and repeatedly embed Using Mathematics and Computational Thinking across the grade band, with explicit SEP element coding (9.A.1, 9.A.2) tied to phenomena: graphing mass vs. volume and finding unit rate/density [E1][E3][E4][E5], using calculators to determine reactant proportions [E2], calculating rate of change/speed and graphing in coordinate quadrants [E8], constructing equations [E9], and ratio reasoning with percent change [E11]. Teacher guidance further names prerequisite CCSS math standards per unit and provides supports for student engagement in the practice [E6][E7][E10][E12], confirming structural design intent. This satisfies all required components of the indicator.

The materials extensively engage students in both elements of this practice. Constructing explanations is explicit: students 'construct an explanation for how increased temperatures can cause changes to a community's water resources' and use empirical evidence and reasoning to support/refute explanations [E1][E2][E3], aligned to MS-ESS3-1 [E5]. Designing solutions is equally developed: students define problems, criteria, and constraints, weigh tradeoffs and scales, develop viable community solutions [E4][E6][E12], and test/evaluate/combine designs using a Design Testing Matrix [E7][E9][E10]. This structural evidence across multiple units (Earth's Resources, Chemical Reactions) shows the practice is intentionally and repeatedly supported.

The materials intentionally and repeatedly support Engaging in Argument from Evidence: dedicated 'Supporting Students in Engaging in Argument from Evidence' teacher-guidance boxes [E1], explicit SEP performance expectations to construct/present written and oral arguments supported by empirical evidence and reasoning [E2][E4][E5], and structured scaffolds for making a claim, citing specific data as evidence, and connecting it to key model ideas as reasoning [E3][E7]. Answer keys with exemplary-response elements and scoring guidance for student arguments [E6][E8][E11] plus aligned ELA argumentation standards (W.7.1.A–E) [E9][E10] confirm the practice is embedded across multiple lessons with formative assessment. All required components are structurally present.

The materials explicitly embed the Obtaining, Evaluating, and Communicating Information practice with grade-band placement and NGSS alignment (E1, MS-ESS3-5), and provide structured tasks where students gather, evaluate source credibility, and communicate (E5, E8 cite CCRA.W.8 assessing credibility/accuracy, SL.2 evaluating diverse media, SL.4/W.2 presenting and writing informative texts). Communication is scaffolded with explicit audiences and multiple formats (PSA, infographic, blog, podcast, letter) plus peer/parent/community feedback and revision cycles (E12), and is assessed via dedicated rubrics that progress from communicating about a single action to tailoring information for a specific audience (E4, E11). This structural evidence—named practice, standards alignment, rubrics, and audience-specific communication tasks—supports all required components.

The retrieved evidence shows the Patterns crosscutting concept is intentionally and repeatedly built into instruction, with explicit teacher-guide callouts labeled 'DEVELOPING AND USING PATTERNS' that cue students to use patterns as a lens for observations [E2, E6]. Students apply patterns across observations of organisms [E1], comparisons across case studies [E3], population data over time [E4, E11], and structured I2 data analysis [E12]. The CCC is also formally tagged at the lesson level in performance expectations and assessment guidance ('Asking Questions and Defining Problems, Patterns'; 'Mathematical Reasoning... Patterns') [E7, E8], confirming deliberate alignment rather than incidental use.

The materials provide robust, intentional structural support for the cause-and-effect crosscutting concept. A dedicated cause-effect scaffold and sentence frames are introduced early and deliberately revisited across the unit (e.g., predictions via 'when we change (cause), we will observe (effect)' [E1], question frames in [E2][E4], and a fill-in-the-blank scaffold that grows into an interaction table in Lessons 1, 6, and 9 [E3][E8][E9]). Students actively use the framework to make sense of phenomena rather than passively hearing about it [E8], and the concept is deepened with correlation vs. causation distinctions in grade 6 [E5][E12] and explanatory 'because' clauses connecting cause to mechanism [E6]. This evidence covers all required components of the indicator.

The materials explicitly and intentionally develop the Scale, Proportion, and Quantity crosscutting concept across multiple grade-7 units with named CCC callouts and aligned standards. In Chemical Reactions & Matter, students determine the mass-to-volume ratio (unit rate/density), graph the proportional relationship, identify the constant of proportionality, and reason about doubling volume — all explicitly tagged as 'scale, proportion, quantity' ([E1], [E2], [E4], [E6], [E9]). The materials also trace the CCC progression from grades 3–5 ([E5]) and apply it in Chemical Reactions & Energy, where students scale up reactants while maintaining proportion ([E3], [E7], [E8]). This structural evidence — explicit CCC labeling, math-standard alignment, and teacher-guide design rationale — supports all required components.

The CCC Systems and System Models is explicitly named as a unit-level crosscutting concept [E1] and is intentionally developed throughout: students build and update a class Carbon System Model and water-system model [E7][E8], construct a causal diagram that unifies the carbon and water systems to explain how fossil fuel use affects water resources [E4][E6], and use systems thinking to reason about subsystems (individuals, families, schools) nested within the larger community system [E9]. This structural evidence—named CCC, teacher-guidance prose describing system modeling, and assessment look-fors tied to system components [E3][E10]—shows the materials deliberately support this indicator across all its required components.

The Crosscutting Concept of Energy and Matter is explicitly named and intentionally integrated across multiple grade-7 lessons in both the Matter Cycling & Photosynthesis and Metabolic Reactions units. Lessons repeatedly pair the CCC with specific performance objectives and checks for understanding — e.g., tracking matter cycling and energy flow through organisms [E7], explaining cellular respiration inputs/outputs [E1, E6], conservation of matter in open vs. closed burning systems [E10, E12], and modeling how bears rearrange matter to release energy during hibernation [E9, E11]. The 'What to look/listen for' guidance shows students are explicitly held accountable for reasoning with Energy and Matter [E4, E8, E9], demonstrating deliberate structural support for the indicator.

The grade-6 Cells & Systems unit intentionally and systematically develops the Structure and Function crosscutting concept, with explicit grade-band progression noted ('attends to the 3-5 grade band' and builds toward MS-LS1-1/2/3) [E6][E10]. Students repeatedly relate structures to functions across multiple lessons—dissection observations [E1][E7], microscopic cell structures [E6][E9], and nerves [E11]—captured on the recurring 'Our Body as a System' poster designed around this CCC [E3][E5][E8]. Teacher guidance defines the term as both noun and verb, adds it to the Word Wall, and explicitly frames the CCC lens for sensemaking [E4][E12][E2], demonstrating clear structural support for all components of the indicator.

The Stability and Change crosscutting concept is structurally and intentionally developed across multiple grade bands. Grade 7 explicitly states students 'use the lens of stability and change' from the first lesson of the unit [E10], with dedicated 'Developing and Using Stability and Change' teacher callouts [E2][E8] and student work distinguishing what is stable vs. changing in atmospheric gases [E7]. Grade 8 ties Stability and Change to natural selection through revised models showing trait stability and distributional change [E4][E5][E6][E11], and Grade 6 names it as an intentionally developed focal CCC [E12], demonstrating coherent multi-grade support.

Nearly every unit across grades 6-8 contains a dedicated, intentionally designed 'Connections to the Nature of Science' section that names specific grade-band NOS elements and describes precisely how students develop them ([E1]-[E12]), demonstrating consistent support for teachers and students across contexts. Multiple NOS-SEP elements are explicitly coded and developed—logical/conceptual connections between evidence and explanations [E1][E9][E10], science depends on evaluating/revising explanations [E2][E3][E9], and using a variety of methods/tools [E4][E5][E6][E8][E12]—and Engineering/ETS connections appear as well [E7]. This structural, consistent, cross-grade design meets the 2-point bar for demonstrating how the dimensions connect across contexts with explicit teacher support.

Evidence shows comprehensive teacher guidance for enacting both student and ancillary materials: Learning Plan Snapshots with part-by-part durations, summaries, slides, and materials [E2], plus structured unit storylines mapping phenomena to what students figure out [E1, E11]. Annotations are presented within the context of specific lesson-level performance expectations and three-dimensional goals — e.g., 'When to check for understanding / What to look and listen for' callouts tied to named PEs [E3, E5, E9], Assessment Opportunity boxes building toward specific objectives [E8], and concrete enactment supports like scripted teacher moves and 'Additional Guidance' on materials handling [E6, E7, E10]. All guidance keeps explicit attention on engaging students in figuring out phenomena (flameless heaters, bath bombs, floods/droughts) and solving design problems, satisfying both required components.

The materials provide a documented assessment system with multiple opportunity types throughout each unit and across the series—pre-assessment, formative, summative, and student self-assessment—embedded and flagged via an 'Assessment Icon' in teacher support boxes ([E1][E2]), plus lesson-by-lesson LLPE assessment opportunity tables in every grade ([E4][E10]). Teacher guidance for interpreting performance is present through scoring guidance and rubrics ([E3][E11]) and an explicit Assessment and Scoring section. Follow-up suggestions are evident, e.g., using exit tickets to gauge 'whether students need more support' and strategically selecting LLPEs to assess and provide timely feedback ([E5][E4]). This structural evidence spans grades 6-8 and meets all required components.

Both required components are supported. Materials provide adult-level explanations of grade/course-level concepts through teacher guidance, DCI/SEP/CCC targeted elements, rubrics, and answer keys (E2, E3, E10, E12) plus 'what students will figure out' summaries (E1, E11). They also explicitly show how concepts align to other grade/course levels by naming prerequisite standards from prior grades — e.g., grade-6 ratio/unit-rate CCSS cited as prerequisites in grade 7 (E5, E8) and grade-7 probability CCSS surfaced in grade 8 genetics (E7), with teacher guidance on making those cross-grade math connections (E2).

Strong structural evidence shows assessments are designed to capture the full intent of grade-band standards across the series: every OpenSciEd lesson includes lesson-level performance expectations (LLPEs) explicitly built for three-dimensional learning, combining SEPs, DCIs, and CCCs with font-coded alignment to each NGSS dimension [E3, E5, E6, E7, E8, E9, E10, E11, E12]. Lesson-by-lesson assessment tables summarize opportunities to assess every LLPE via handouts, home learning, progress trackers, and discussions, spanning all three grade levels (6, 7, 8) and many units [E10, E11, E12], with transfer/application tasks giving students opportunities to use all three dimensions to make sense of phenomena [E1]. ELA standard connections within assessment tasks further show alignment breadth [E2]. This consistent, series-wide assessment architecture supports all required components of the indicator.

The materials provide explicit standards correlation tables for college- and career-ready ELA and mathematics standards across multiple units and grades, including dedicated 'ELA Common Core College and Career Readiness Standards Connections' tables (E1, E3, E7, E8, E12) and math CCSS connections (E9, E10). They also explain the role of these standards in the overall series: E2 and E7 describe how projects align to different ELA/math/technology standards by modality and how to use them for cross-curricular connections, while E9 explains the vertical progression of math standards (developed in elementary, utilized in middle school, revisited in high school) and cautions about grade-level appropriateness. This combination of correlation information plus contextual explanation of the standards' role satisfies the indicator's required components.

The materials explain the program's instructional approaches—the OpenSciEd instructional model centered on phenomena-driven sensemaking, iterative knowledge-building, classroom discourse, and unit routines (E2, E9, E11), with strategies elaborated via callout boxes and the OpenSciEd Teacher Handbook (E2, E7, E10). They also explicitly reference research-based strategies, citing named studies such as Fortus et al. (2019), Nordine, Krajcik, & Fortus (2011), and A Framework for K-12 Science Education to justify the energy-instruction approach (E1, E8), plus UDL principles informing equity design (E3-E6, E12). Both required components are clearly met.

The materials include explicit per-lesson 'Materials List' sections organized by per student / per group / per class across multiple lessons and units, e.g. Lesson 1-4, 6, 9 in Unit 7.2 [E1][E5][E6][E7][E8] and Unit 7.4 [E10], plus a Forces at a Distance lesson in grade 8 [E11], demonstrating a consistent structural feature across the series. They also specify exact quantities (e.g., '40 g baking soda,' '110 mL room-temperature water') and include detailed advance-preparation/tray-setup instructions [E3][E12][E9], confirming a comprehensive, instruction-aligned supply list. This satisfies the single requirement for the 1-point band.

The materials provide clear, consistent science safety guidelines for teachers and students across every grade-band unit (6-8), as shown by near-identical safety language appearing in all twelve units [E1]-[E12]. These guidelines specify engineering controls and PPE (goggles, non-latex aprons/gloves, eyewash/shower, fume hood, fire extinguishers), require qualified adult supervision, mandate annual review of procedures, direct teachers to follow school/district/legal safety policies [E2][E3][E12], and call for students to be reminded of specific safety procedures before each investigation. Critically, each lesson includes teacher guidelines for applicable safety procedures covering setup, running, takedown, disposal, and storage [E1][E4], demonstrating safety guidance is embedded throughout the instructional materials.
