1 of 7

D2.1

Strand D · Structures and Mechanisms identify internal forces acting on a structure, and describe their effects on the structure

D2.2

Strand D · Structures and Mechanisms identify external forces acting on a structure, and describe their effects on the structure

D2.3

Strand D · Structures and Mechanisms describe forces resulting from natural phenomena that can have severe consequences for human-built structures, and identify structural features and materials that can allow such structures to withstand these forces

Every lesson follows Ontario's 4-part structure. Minds On, Direct Instruction, Guided Practice, Consolidation. With timings, teacher moves, IEP and ELL supports, and look-fors built in.

7 of 7

Topic: Forces Acting on Structures Time: 60 minutes I can: identify internal and external forces and describe how each affects a structure

Minds On 8 min

Ask: Think about a bridge you have crossed. What do you think is pushing or pulling on it right now, even when no cars are on it? Think-pair-share one external force and one internal force. Listen for: students who recognize gravity pulling down (external) and materials being squeezed or stretched (internal). ELL support: gesture pushing palms together for compression, pulling fists apart for tension.

Direct Instruction 10–12 min

Introduce two categories: external forces (gravity, wind, load, water) and internal forces (compression, tension, shear, torsion). Model with a cardboard tube: push both ends to show compression, bend it to show tension on top and compression below. Check for understanding: thumbs up if students can name the force that squeezes a material. IEP/ELL anchor chart provided.

Guided Practice 12–15 min

Pairs read the reading resource on Chromebooks and complete worksheet Part 1 and Part 2 together, sorting scenarios as internal or external and naming the specific force. Circulate for: students correctly distinguishing the external agent (wind) from the internal response (compression). Extension for early finishers: analyze forces on a real Ontario structure like the CN Tower.

Independent Work 12–15 min

Students complete the rest of the worksheet individually on Chromebook. Teacher confers with students who struggled during guided practice, prompting with the anchor chart and gestures.

Consolidation 5 min

Exit ticket: name one external and one internal force acting on a school building, and explain how the internal force is caused by the external force. Level 3 looks like: student identifies gravity or wind as external, names compression in walls or tension in roof beams, and connects the two.

A real student-facing worksheet. 14 questions across 4 sections. Fill-in-the-blank, multiple choice, sorting, and short-answer. Print it, or share a link students can submit on any device.

Ontario Achievement Chart, 4 levels. Science-specific categories: Knowledge & Understanding, Thinking & Investigation, Communication, Application. Defensible to admin, ready to use for assessment.

6 of 7

Category	Level 1	Level 2	Level 3	Level 4
Knowledge & UnderstandingKnowledge of force types and their effects on structures	Identifies few force types; limited understanding of internal vs. external.	Identifies some force types; partial understanding of the distinction.	Identifies most force types; solid understanding of how internal forces arise from external ones.	Identifies nearly all force types; thorough, precise understanding with clear cause-and-effect articulation.
Thinking & InvestigationAnalyzing scenarios and sorting forces into correct categories	Sorts scenarios with limited accuracy; relies on prompting.	Partial accuracy; occasionally distinguishes external source from internal response.	Sorts accurately in most cases; consistently distinguishes source from response.	Insightful, independent reasoning; precisely explains each external–internal relationship.
CommunicationUsing scientific vocabulary accurately in writing and discussion	Little or no scientific vocabulary; unclear explanations.	Some vocabulary with partial accuracy; understandable but lacks detail.	Most vocabulary used correctly; clear, sufficiently detailed explanations.	Precise, confident use of vocabulary; thorough, well-organized explanations.
ApplicationConnecting force concepts to real-world structures	Limited or unclear connections to real-world structures.	Some connections, mostly general or based only on examples from the lesson.	Meaningful connections to familiar structures beyond those modelled.	Accurate, insightful connections to new contexts; extends thinking independently.

Common questions

The stuff teachers ask before signing up.

Is my student data safe? +

Yes. Your data stays in Canada on Supabase's Canada Central servers. Student names are never sent to the AI. Only anonymized accommodation notes like "ELL Level 2" are used for personalization. Built with Ontario's MFIPPA in mind from day one.

Is using AI for lesson planning actually okay? +

TeacherAI doesn't replace your professional judgment; it gives you a starting draft instead of a blank page. Every lesson, assessment, and comment is yours to review, edit, or rewrite before it reaches a student or parent. The AI drafts. You decide.

What if I don't like what it generates? +

Edit it. Every lesson, worksheet, rubric, and comment is fully editable in your browser. Worksheets have a "More Questions" button if you need extras. Report card comments regenerate per student. You're never stuck with the first draft.

Does it do full unit plans, not just single lessons? +

Yes. Pick a unit topic and TeacherAI drafts a scope and sequence with expectations coverage, big ideas, and an assessment plan. Choose anywhere from 2 to 12 lessons. Each lesson can be expanded into a full plan with worksheet, rubric, and answer key. The whole unit prints as a single PDF for TPA evidence or long-range binders.

Does it really work for split grades? +

Yes. This is one of the things TeacherAI was built for. Pick multiple grades (1/2, 4/5, 6/7) and get separate worksheets per grade with grade-appropriate expectations. The lesson plan handles differentiation. Each student is tracked against their own grade's expectations. Works for any split from Grades 1 through 8.

Will it work for Kindergarten? +

Yes. TeacherAI supports the new Ontario Kindergarten Curriculum (2026) with play-based "Play Invitation" lesson plans, K-specific worksheets with images, and observation-based assessment instead of Level 1-4 rubrics. Activities are designed for print-and-write. Kids draw, trace, and circle on paper while you observe.

What can TeacherAI do that a general chatbot can't? +

ChatGPT and Gemini can write a rough lesson if you prompt them well. They can't do the things that actually connect across your term:

Expectation tracking that feeds report cards. Every expectation you teach and mark all term flows into draft report card comments automatically. No retyping, no searching through your markbook at 9pm in June.

AI-suggested marks with observation feedback. Paste a student's work and get a Level 1-4 suggestion with Growing Success-aligned feedback in 30 seconds — no roster required. Or run a whole class: students submit on any device, TeacherAI marks every question for every student. Turns a week of marking into an afternoon.

Real Ontario expectation codes. Not "understands fractions" — actual B1.3 from the 2020 math curriculum, pulled from 1,300+ expectations across all K-8 subjects.

Printable, split-grade, Ontario-shaped output. Rubrics in Level 1-4. Worksheets per grade in a split. ETFO-conscious language ("suggest" not "auto-grade"). Ready for a TPA, not a reformat.

How is this different from TeachersPayTeachers? +

TPT is a marketplace. You search for something close to what you need, hope it fits your class, and pay per unit. TeacherAI generates lessons, worksheets, and rubrics for your exact topic, grade, and split. Everything aligns to the current Ontario curriculum and is fully editable. Many teachers use both: TPT for pre-built thematic units, TeacherAI for everything in between.

The marking, tracking, and report cards — handled.
