# Ontario Grade 6 Science and Technology — 9 November 2026

This dependent proposal reviews **55 retained codes: 44 specific and 11 overall**.
It builds on the unmerged Grade 5 proposal at `57d8edb3a6de268c16f81ced63b24153bfd7196a`, including reviewed
Grade 1–4 components and the optional existing-ID follow-up note. The exact base
and dispositions are retained in the
[code-by-code mapping](ontario-grade6-science-mapping-2026-11-09.json).
This is not accepted-main or deployed state. Current review stops at primary
Grade 6; historical Grade 7/8 catalogue entries do not expand the authoring scope.

## Outcome

| Scope | Full semantic support | Partial | New topics proposed |
| --- | ---: | ---: | ---: |
| 44 specific expectations | 17 | 27 | 0 |
| 11 overall expectations | 0 | 11 | 0 |

The proposal adds **103 distinct pairs across 40 specific codes and 78 existing
topics**, in 78 new Canada/Ontario **11–12** contexts. All prior intervals and
associations are preserved. No global start age is lowered. Topic identities,
authored claims/assessment, dependencies and authored research remain unchanged.

Full is an authoring source-fit judgment, not learner mastery, delivered teaching
or consumer eligibility. Partial conditions and candidate-only claims do not
request new topics. Overall expectations are reviewed independently of child-link
counts and may differ in scope from their specific children.

provides process context on printed pages 69–80 and Grade 6 on 146–156. All
44 specific paragraphs independently match the sources. Normalization removes
the extracted publisher copyright footer and joins the A3.2 hyphen line wrap;
no requirement content is discarded.

All-domain searches inspect complete descriptions, evidence, assessment and
prerequisites. Public artifacts contain source keys and our judgments, without
restricted expectation wording, PDFs or private operational data.

## Reuse and conservative boundaries

- **Biodiversity:** the existing species-variety/keystone claim already explains
  benefits, resilience and loss cascades. Same-species variation and survival
  explanations also exist. Neither is replaced with a new Ontario biodiversity
  topic. The complete multi-level diversity and within/among-community account
  remains Partial; the later broader resilience claim is not lowered.
- **Interactions:** colony roles, symbiosis, food webs and habitat engineering are
  real contributions across interaction categories. Merely listing them does not
  certify an integrated explanation of sustained diversity.
- **Classification:** existing grouping, unfamiliar-organism evidence and keys
  supply further classification. No unlisted compulsory advanced taxonomic-rank
  scheme is invented.
- **Local invasive case:** an authoritative CFIA reference localizes existing
  invasion/harm and biodiversity reasoning. This supplies an example resource,
  not a new provincial topic. Harmful invasion is distinguished from harmless
  introduced status; declining abundance is not automatically species extinction.
- **Electricity:** current and static charge explanations, conductor tests,
  conversion/device work and circuit-component functions already exist. Basic
  configuration vocabulary contributes to series/parallel comparison, while the
  complete common-use account remains explicit. The later full circuit-rules
  claim retains its age and meaning.
- **Applied performances:** a planned local conservation response is not an action
  already carried out. Private energy choices do not automatically establish
  school advocacy. These are performance conditions, not missing mastery IDs.
- **Flight:** drag, weight, force balance and structure/function arguments are
  actual components. They do not establish every lift/thrust relationship or
  machine/organism control application. Upthrust terminology is not silently
  equated with a complete aerodynamic-lift explanation. No new flight topic is
  requested in this batch.
- **Independent overall scope:** D1 concerns environmental aviation effects;
  D1.1 concerns societal effects and local/global perspectives. The overall remains
  independently Partial rather than inheriting an answer from its single child.
- **Space:** existing objects, mass/weight, geometry and observation technologies
  supply substantial knowledge. General astronaut/needs lists are not substituted
  for actual space-condition responses. The later Mars/SETI claim is not lowered
  for one matching human-needs clause. Checked space-impact cases remain explicit.
- **Community resources:** generic farming, generation sources and conservation
  knowledge do not establish culturally specific agriculture or Canadian community
  impacts. Appropriate sources and relevant case judgments remain required;
  Australian cultural evidence is not relabelled.

## Verified Ontario localization

The [CFIA emerald ash borer reference](https://inspection.canada.ca/en/plant-health/invasive-pests-and-plants/insects/emerald-ash-borer)
was read and captured 9 November 2026. It verifies Ontario occurrence and the
insect's feeding/mortality effects on ash. The HTML capture hash is retained as
supplementary evidence in the mapping. This is a factual local example supporting
B2.6, not another curriculum authority, pest-management advice or a requirement
that every school use the same organism.

## Proposed source-fit checks

These are proposed review tasks, not learner observations or canonical assessment
changes.

| Codes | Positive case | Near miss to reject | Transfer check |
| --- | --- | --- | --- |
| B2.3 | Explain why varied same-species traits can support survival under changed conditions. | Every difference is assumed helpful in every environment. | Predict a different stated environmental challenge with reasons. |
| B2.6 | Relate the verified local insect/ash effect to native organisms and the community. | All introduced organisms are called invasive, or any decline is called immediate extinction. | Explain another supplied harmful-introduction case using the same criteria. |
| C2.2 | Contrast accumulated charge/discharge with charge flow around a circuit. | Say both are identical because both may produce sparks or light. | Classify a different stated electrical event with reasons. |
| D2.2 | Identify actual drag/weight components and state which parts of the flight account remain unproven. | Call any upward force aerodynamic lift or declare two arrows a complete four-force explanation. | Use a supplied flight scenario to test the complete force relationship before judging Full. |
| E2.5 | Explain changing lunar appearance, eclipses and other relative-motion effects. | Attribute ordinary lunar phases to Earth's shadow. | Predict a different stated Sun/Earth/Moon arrangement. |

## Remaining conditions and validation

Multi-level biodiversity/resilience integration, enacted local conservation,
verified Indigenous agricultural cases, Canadian electricity/community impacts,
school advocacy, varied electrical generation, common circuit uses, complete
flight/control explanations and verified space-needs/impact judgments remain
explicit. These are not a pre-approved topic-creation backlog.

The diagnostic lists **81 distinct hard-prerequisite IDs** without an
explicit Ontario interval spanning 11–12. It is not a consumer selection rule.
Global/framework guidance and actual consumer behavior need separate review;
missing Ontario prerequisite intervals do not erase semantic support. No invented
source link, age-only association or dependency edit clears the diagnostic.

Public validation and generated-artifact checks pass. Exact checks preserve all
prior contexts and Grade 1–5 reports, authored fields, dependencies, catalogue,
clusters and archived research. Compatibility fields and research bindings change
only as required by the new associations. Source paragraph comparison, public
text-screen and report-link checks pass.

All primary Science grade code sets now have a reviewed proposal somewhere in this
dependent chain. This means the audit is comprehensive by selected code, not that
all expectations are fully covered or that Ontario's other subjects are complete.
No DB/learner writes or publication receipt are included. Reconcile unmerged
bases with accepted content before downstream handoff.
