How OpenLab Science compares

A capability-by-capability comparison against six other physics and science lab products, researched and re-verified from public sources. Ordered the way a teacher or department actually evaluates: does it match my curriculum, is the lab itself good, does it support how a class runs, is the AI help real, who can access it — and last, what does it cost.

Curriculum & standards coverage

Named framework coverage

How many named standards (NGSS, AP, IB, state, etc.) does it map to at all?

• OpenLab Science (Yes): 8 named frameworks with real unit maps: NGSS High School Physical Science, general High School Physics, AP Physics 1, AP Physics 2, AP Physics C: Mechanics, AP Physics C: E&M, IB Physics (all five DP themes), and NGSS Middle School Physical Science.
• PhET Interactive Simulations (Partial): No official first-party framework map found. The site hosts a community-submitted “Alignment of PhET sims with NGSS” activity, which is not the same as an official, maintained standards correlation.
• ExploreLearning Gizmos (Partial): NGSS alignment (including Disciplinary Core Ideas, Science & Engineering Practices, and Crosscutting Concepts) is claimed for Gizmos Investigations, and the broader library is described as correlated to state standards, curricula, and textbooks.
• Pivot Interactives (Yes): NGSS, AP, and IB are named, plus customizable state-standard correlation — broad claimed coverage.
• Labster (Yes): AP, IB, GCSE/A-Levels, and NGSS are named; a separate skills page also references ACS and AAPT mappings.
• The Physics Classroom (Task Tracker) (Partial): Supports AP Physics 1 course use, but the site’s own lesson-plan notes state core materials were not originally designed around NGSS — a materially narrower and more qualified claim than the other products compared here.
• Inq-ITS (Partial): “NGSS-aligned” is claimed at a general level on the homepage; a detailed, per-unit official map was not found.

Mapping depth

Is a standard tagged in marketing copy, or is each unit mapped to specific labs a teacher can actually assign?

• OpenLab Science (Yes): Every mapped unit lists the specific labs that satisfy it — not a blanket “correlates to NGSS” tag. A teacher can open a framework page and see exactly which investigations cover which unit.
• PhET Interactive Simulations (No): No per-unit official mapping was found to evaluate.
• ExploreLearning Gizmos (Partial): Investigations are tied to specific NGSS elements; how granular and complete that mapping is across the full library was not established from public sources.
• Pivot Interactives (Not confirmed): How granular the per-unit mapping is behind that claim was not established from public sources.
• Labster (Not confirmed): How granular the per-unit mapping is behind those claims was not established from public sources.
• The Physics Classroom (Task Tracker) (No): No per-unit official standards map was found.
• Inq-ITS (Not confirmed): How granular the per-unit mapping is behind that general claim was not established from public sources.

Simulation & lab capability

Library size

How many simulations, labs, or investigations does the product publish? (We mark full at 100+ published presets/simulations.)

• OpenLab Science (Yes): 138 curated presets across 8 physics modules (mechanics, fluids, waves, thermo, circuits, electricity & magnetism, optics, modern physics) — over our 100-preset bar for a full mark. Smaller than PhET’s 174 or Gizmos’ 550+, and narrower in scope — physics only, not general K-12 science.
• PhET Interactive Simulations (Yes): 174 interactive simulations, per PhET's own simulation filter (counted 2026-09-12) — the largest single free library among the products compared here.
• ExploreLearning Gizmos (Yes): 550+ math and science simulations for grades 3–12 — the largest claimed library here, though it spans far more than physics.
• Pivot Interactives (Yes): 500+ activities — mostly interactive-video and sensor-based measurement investigations, not simulations. This is a different medium by design, not a smaller version of a simulation library.
• Labster (Yes): 300+ virtual labs across STEM — broad, but spanning far more than physics, and built for a higher-education audience first.
• The Physics Classroom (Task Tracker) (Partial): 81 Concept Checkers across physics and chemistry topics (counted on the live Concept Checkers index, September 2026), each tied to a simulation or tutorial page — the vendor separately advertises 700+ HTML5 interactive modules site-wide; this counted subset is the smallest simulation library among the products compared here
• Inq-ITS (Yes): 150+ investigations in its virtual-lab collection, spanning science broadly — the physics-specific subset is likely smaller than this headline figure.

Interactivity depth

Can a student freely build/configure a scene, or is the experience a fixed simulation, video, or scripted narrative?

• OpenLab Science (Yes): Every module is a buildable 2D scene — students place, connect, and configure real objects, not just move a slider on a fixed layout.
• PhET Interactive Simulations (Partial): Simulations are interactive with adjustable parameters, but generally not freely buildable scenes the way a sandbox is; depth varies a great deal by individual simulation.
• ExploreLearning Gizmos (Partial): Simulations and guided Investigations/STEM Cases are interactive but largely structured and canned rather than freely buildable.
• Pivot Interactives (Partial): Pivot’s model is real, recorded video and live sensor/uploaded-video measurement rather than a free-build simulation sandbox — a deliberate choice to use real physical phenomena, not a gap.
• Labster (No): Labster’s labs are immersive, scenario-led, and largely scripted rather than a freely buildable sandbox — a deliberate 3D-narrative design for realism, not a gap in a simulation product.
• The Physics Classroom (Task Tracker) (Partial): A mix of tutorials, problem/practice tools, HTML5 Interactives, and concept-check challenges — closer to a concept-practice and reference product than a lab-simulation platform, which is a different category, not a smaller version of one.
• Inq-ITS (Partial): Structured virtual inquiry investigations built around forming hypotheses and analyzing data, not a free-build simulation sandbox — a deliberate assessment-first design, not a gap.

Narrated lessons & built-in instruction

Does the product teach the concept itself — narrated instruction with worked examples before or alongside the lab — or is teaching left entirely to the teacher?

• OpenLab Science (Yes): 42 narrated concept lessons cover every preset: a law explanation, a formula symbol breakdown, a worked example, and self-check quizzes, presented by an avatar teacher with voice narration and captions. Text and voice are translated into all 46 UI languages, and any lesson replays from the preset guide.
• PhET Interactive Simulations (Partial): Some simulations can voice their own on-screen descriptions — a self-voicing accessibility feature that varies by simulation — but there is no narrated concept-lesson layer; PhET's teaching resources are written activities, not narrated instruction.
• ExploreLearning Gizmos (Not confirmed): First-party sources conflict: ExploreLearning's help center states Gizmos include no spoken audio, while its accessibility marketing describes on-screen text being read aloud in most scenarios. No narrated lesson layer was confirmed either way.
• Pivot Interactives (Not confirmed): Pivot's medium is real video of physical phenomena, not narrated instruction; no narrated concept-lesson layer was found in public sources.
• Labster (Partial): Genuinely narrated labs: the Dr. One assistant and other characters speak throughout the simulations, and an accessibility mode adds spoken descriptions. But the narration lives inside scripted scenario labs — there is no per-concept lesson library with worked examples, and the voice languages are far fewer than 46.
• The Physics Classroom (Task Tracker) (Partial): The Tutorial is a genuinely deep written instruction layer (with Concept Builders practice), but it is text on a page — no narrated audio instruction was found.
• Inq-ITS (Not confirmed): Rex, the AI tutor, coaches students during the inquiry workflow (hypothesis, data, CER writing); whether that coaching is spoken or text-only was not confirmed from public sources.

Live formula + SI-unit transparency

Does the product show the substituted equation and SI-unit readouts behind a live result, not just the result?

• OpenLab Science (Yes): The headline product differentiator: module formula panels evaluate the real symbolic formula with the scene’s current values live, and every readout carries its SI unit.
• PhET Interactive Simulations (Not confirmed): Could not confirm a consistent, platform-wide live substituted-formula display from public sources; behavior varies by simulation, and the absence of a central claim is not proof of absence.
• ExploreLearning Gizmos (Not confirmed): Could not confirm a consistent, platform-wide live substituted-formula display from public sources.
• Pivot Interactives (Partial): Calculated table columns, units, graph-fit equations, and RMSE are supported; a live simulation-state-to-substituted-formula panel does not apply in the same way to a video-measurement product and was not confirmed.
• Labster (Not confirmed): A consistent, platform-wide live substituted-formula display was not confirmed from public sources.
• The Physics Classroom (Task Tracker) (Not confirmed): A consistent, platform-wide live substituted-formula display was not confirmed from public sources.
• Inq-ITS (Not confirmed): The verified workflow centers on hypothesis, data collection, analysis, and claim-evidence-reasoning (CER) writing, not a live substituted-formula display; not confirmed as a capability at all.

Data tables, graphing & analysis

Are in-product tools for recording, graphing, and analyzing trial data built in?

• OpenLab Science (Yes): Live graphs, a recorded measurement history, and readouts with units, exportable to CSV. Breadth varies by module.
• PhET Interactive Simulations (Not confirmed): Could not confirm a consistent, platform-wide data-table/graphing tool from public sources; varies by simulation.
• ExploreLearning Gizmos (Partial): Data collection, analysis, and graphing are marketed as part of Investigations; the exact tools available vary by individual Gizmo.
• Pivot Interactives (Yes): A genuinely strong, dedicated toolset: data tables, calculated columns, multiple graph types, curve fits with RMSE, and uncertainty bars.
• Labster (Partial): Some labs allow generated data to be downloaded; a common cross-lab table/graph workbench was not confirmed.
• The Physics Classroom (Task Tracker) (Not confirmed): A common cross-activity data/graphing workbench was not confirmed from public sources.
• Inq-ITS (Partial): Students collect and analyze trial data and select supporting evidence at a workflow level; the depth of graphing-tool coverage per investigation was not confirmed.

Browser-based, no install

Does it run in an ordinary browser with no software or app installation?

• OpenLab Science (Yes): Runs as an ordinary browser web app; no install, no plugin.
• PhET Interactive Simulations (Yes): Runs in-browser, with optional offline and app access also available.
• ExploreLearning Gizmos (Yes): First-party system requirements describe browser/device access with no install.
• Pivot Interactives (Yes): Explicitly a web application; no downloads or apps required (an internet connection is required).
• Labster (Yes): Browser-based on computers, Chromebooks, iPads, and Android tablets.
• The Physics Classroom (Task Tracker) (Yes): HTML5 Interactives and web activities run in-browser.
• Inq-ITS (Yes): Supports current Chrome, Firefox, and Safari.

Investigation & assignment workflow

Printable worksheets + answer keys

Are printable student worksheets available, with a real answer key for teachers?

• OpenLab Science (Yes): All 138 presets have a printable 5E-model lab sheet, with a signed, email-verified teacher unlock for the filled-in answer key.
• PhET Interactive Simulations (Partial): Community and PhET-provided activity worksheets exist, alongside per-simulation Teacher Tips (behind a free sign-in), video primers, and alignment documents — but not every activity has a worksheet, and answer-key availability is inconsistent across the library.
• ExploreLearning Gizmos (Yes): Customizable Student Exploration Sheets are provided in Google Docs, Word, and PDF, with teacher answer keys.
• Pivot Interactives (Not confirmed): A product-wide printable worksheet-plus-answer-key offering was not confirmed; activities are primarily completed online.
• Labster (Partial): Downloadable lab manuals and report templates, plus editable quiz documents with and without answers, are provided as simulation supplements.
• The Physics Classroom (Task Tracker) (Yes): Free printable Think Sheets are available; paid Solutions Guides and course packages add answer keys and lab sheets.
• Inq-ITS (Partial): Student work can be saved or printed as PDF; a product-wide printable-worksheet-plus-answer-key library was not confirmed.

Investigation notebook / evidence capture

Is there a structured, in-product record of a student’s hypothesis, data, and conclusion?

• OpenLab Science (Yes): A structured investigation notebook and evidence-pack system covers all 138 presets, free and open to any teacher — no account or sign-up required.
• PhET Interactive Simulations (No): No integrated investigation notebook was found; external and community-authored activity sheets exist separately.
• ExploreLearning Gizmos (Yes): Gizmos Investigations include in-product experiment design, data collection and analysis, an “Evidence Picker,” conclusions, autoscoring, and teacher heatmaps — a genuinely structured evidence workflow.
• Pivot Interactives (Yes): Pivot markets itself directly as a digital lab notebook — instructions, data tables/graphs, written analysis, feedback, and scoring in one workflow.
• Labster (Partial): A downloadable lab-report template (synopsis, hypothesis, procedure, results, conclusions) is provided; an integrated, in-product investigation notebook tied to live lab state was not confirmed.
• The Physics Classroom (Task Tracker) (Not confirmed): Worksheets and lesson materials exist; an integrated evidence notebook tied to live simulation state was not confirmed.
• Inq-ITS (Yes): This is Inq-ITS’s strongest area: a documented workflow of hypothesis formation, designed trials, collected and analyzed data, a claim, selected supporting evidence, and a CER write-up — arguably the most complete structured-evidence workflow among the products compared here.

Teacher assignment, progress & grading tools

Can a teacher assign work, see progress, and grade or auto-grade it in-product?

• OpenLab Science (Yes): Teacher assignment and grading tools cover all 138 presets, free and open to any teacher — build and share an assignment link in minutes, no account required.
• PhET Interactive Simulations (No): No native, in-product assignment collection, progress tracking, or grading was found — PhET Studio explicitly disallows student logins, so no student work flows back to a teacher. Its presets and teacher-resource library are a different thing.
• ExploreLearning Gizmos (Yes): Customizable materials, built-in assessment, real-time progress/response heatmaps, and teacher scoring are documented for Investigations and STEM Cases.
• Pivot Interactives (Yes): Customizable assignments, student collaboration, scoring and feedback, grade export, and LMS integration are documented.
• Labster (Yes): Assignment from an LMS or Course Manager, automated grading, grade sync, attempt tracking, and instructor dashboards are documented.
• The Physics Classroom (Task Tracker) (Yes): Task Tracker provides classes, assignments, instant scoring, progress reports, customizable scoring and due dates, and score export.
• Inq-ITS (Yes): Auto-grading, class and student reports, real-time teacher alerts, and assignments with optional AI-tutor support are documented.

Save / share a configured scene

Can a teacher configure a specific setup and reliably share or reopen that exact state?

• OpenLab Science (Yes): Every preset and every free-built scene is shareable as a compressed link — open it and the exact scene (entities, settings, instruments) reloads. The 10 curated presets additionally keep human-readable parameter links (?mass=2&vx=3…).
• PhET Interactive Simulations (Partial): Free simulations do not offer this. PhET Studio — paid — lets an educator save a configured launch state and share it by URL; sharing with a colleague requires them to hold a license too.
• ExploreLearning Gizmos (Not confirmed): Snapshot images (pictures, graphs, and data captured into a document) are confirmed; a reopenable, shareable configured simulation state was not confirmed.
• Pivot Interactives (Partial): Student assignment work auto-saves for later return; sharing a configured phenomenon/video state with another user was not confirmed.
• Labster (Not confirmed): A shareable, reopenable configured lab state was not confirmed from public sources.
• The Physics Classroom (Task Tracker) (Partial): Task Tracker saves and continues student activity progress across sessions/devices; sharing a configured simulation state was not confirmed.
• Inq-ITS (Not confirmed): Account-based work persistence is implied by the student workflow; a shareable, reopenable configured lab state was not confirmed.

Data export (CSV or similar)

Can recorded data leave the product in a usable format, e.g. CSV?

• OpenLab Science (Yes): Recorded measurement runs export to CSV with units and provenance metadata.
• PhET Interactive Simulations (Not confirmed): Could not confirm CSV export on free simulations from public sources. A separately licensed product, PhET-iO, supports streaming output data and programmatic control for developers.
• ExploreLearning Gizmos (Not confirmed): Raw CSV/data export was not confirmed from public sources; snapshot capture into documents is confirmed.
• Pivot Interactives (Partial): Class and assignment scores export as CSV; separate raw student investigation-data export was not confirmed.
• Labster (Yes): Instructor dashboards export grade and engagement data, and some individual simulations offer generated-data downloads.
• The Physics Classroom (Task Tracker) (Yes): Task Tracker exports scores in spreadsheet format.
• Inq-ITS (Not confirmed): PDF save of student work is confirmed; CSV or raw-data export was not confirmed.

AI guidance

AI tutor / assistant

Is there an AI assistant, and does it actually see the student’s current lab state rather than acting as a generic chatbot?

• OpenLab Science (Yes): A free built-in AI tutor is shipped and genuinely lab-aware: its requests include the current serialized scene, live measurements, and the relevant formula context, not just a chat window bolted on the side.
• PhET Interactive Simulations (Not confirmed): No AI tutor or assistant was found on public PhET pages.
• ExploreLearning Gizmos (Partial): First-party material claims AI-assisted feedback within formative assessment; a conversational, lab-state-aware tutor for students was not confirmed.
• Pivot Interactives (Not confirmed): No AI tutor or assistant was found on public Pivot pages.
• Labster (Not confirmed): A built-in “virtual lab assistant” is claimed and embedded in the lab experience; whether it is genuinely AI-driven versus scripted guidance was not confirmed.
• The Physics Classroom (Task Tracker) (Not confirmed): No AI tutor or assistant was found on public pages.
• Inq-ITS (Yes): Rex is explicitly lab-aware — it responds during hypothesis formation, data collection/analysis, and CER writing, while teachers receive real-time skill alerts. This is a genuinely different kind of lab-awareness than OpenLab’s (process/assessment-focused, versus OpenLab’s live formula/measurement context), not a lesser one.

Accessibility & reach

Account-free student experience

Can students run labs and complete graded work without creating an account — the friction and privacy question for minors and shared devices?

• OpenLab Science (Yes): Every capability — labs, narrated lessons, printable sheets, assignment links, evidence packs, grading — works with no account anywhere in the product. A student on a shared classroom device never signs up or signs in.
• PhET Interactive Simulations (Yes): Simulations run with no account required — student accounts are not allowed at all. PhET's optional educator accounts (about 720,000 registered over five years) exist to share activities and teacher material; none of that is needed to run any simulation.
• ExploreLearning Gizmos (No): An account is required — access runs through teacher and school accounts with paid licenses, and even the 30-day trial requires sign-up.
• Pivot Interactives (No): Student and instructor accounts are required; the product's save-and-return model depends on them.
• Labster (No): Access runs through institutional purchases, LMS integration, or instructor accounts — there is no account-free path for an individual student.
• The Physics Classroom (Task Tracker) (Partial): The free Concept Checkers and tutorials can be used without an account, but the Task Tracker assignment/grading layer requires paid student accounts.
• Inq-ITS (No): Students work inside accounts — class setup and progress tracking depend on them; no account-free path was found.

Accessibility

What accessibility features exist, and is there a public conformance statement (e.g. VPAT) backing them?

• OpenLab Science (Partial): Real accessible controls exist — ARIA roles/labels, live regions, keyboard and click fallbacks — but there is no public WCAG conformance statement or VPAT yet, unlike PhET or Pivot.
• PhET Interactive Simulations (Yes): The strongest accessibility program among the products compared here: pan/zoom (91 simulations), alternative input (64), interactive highlights (57), and self-voicing interactive description (13), backed by disability co-design and a published accessibility statement. Coverage varies by individual simulation.
• ExploreLearning Gizmos (Partial): Keyboard-navigation targets, responsive and minimal-text design, and avoidance of repeated flashing/timed responses are documented; the vendor itself notes some color-contrast coverage is incomplete.
• Pivot Interactives (Yes): A VPAT dated June 2026 is published, alongside keyboard/screen-reader alternatives, accessible tables and video, and a built-in text reader; the vendor states current development targets WCAG 2.1.
• Labster (Partial): Keyboard navigation, screen-reader support, and resizable text are documented as features; coverage is stated to vary by individual simulation, with no platform-wide conformance statement found.
• The Physics Classroom (Task Tracker) (Partial): A 2026-dated Accessibility Conformance Report exists for HTML5 Interactives; its detailed support levels need a dedicated review before treating it as a blanket “yes.”
• Inq-ITS (No): No current first-party accessibility statement or VPAT was found.

Languages supported

How many languages does the product interface support?

• OpenLab Science (Yes): 46 UI locales (English, Arabic, Bengali, Bulgarian, Simplified & Traditional Chinese, Catalan, Czech, Danish, Dutch, Filipino, Finnish, Spanish, Swedish, French, German, Greek, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Norwegian, Persian, Polish, Brazilian Portuguese, Romanian, Russian, Slovak, Croatian, Slovenian, Lithuanian, Latvian, Estonian, Irish, Maltese, Malay, Marathi, Telugu, Tamil, Thai, Turkish, Ukrainian, Urdu, Vietnamese) — printable lab sheets are translated too.
• PhET Interactive Simulations (Yes): The most-translated simulations reach about 90 languages each (per PhET's own per-simulation translation lists, checked 2026-09-12) — more languages than any other product compared here, including OpenLab.
• ExploreLearning Gizmos (Not confirmed): Core simulation interface language count was not confirmed from public sources; Spanish and French lesson resources are documented separately for multilingual learners.
• Pivot Interactives (Not confirmed): Language count was not confirmed from public sources.
• Labster (Partial): 5 languages listed (English, Italian, German, French, Spanish) — fewer than OpenLab's 46; availability varies by simulation.
• The Physics Classroom (Task Tracker) (Not confirmed): Language count was not confirmed from public sources.
• Inq-ITS (Partial): 2 languages: English and Spanish — fewer than OpenLab's 46.

Translated teaching materials

Beyond the interface, how much of the actual teaching material — worksheets, labs, narrated audio — exists in more than one language?

• OpenLab Science (Yes): In all 46 languages: the interface, the printable lab sheets for all 138 presets, and the narrated lesson audio — text and voice, not just menus, but the materials a student actually reads and hears.
• PhET Interactive Simulations (Partial): The simulations themselves are translated (the deepest per-simulation coverage reaches about 90 languages) — a genuinely translated product. The teacher-activity library is community-contributed and not systematically translated.
• ExploreLearning Gizmos (Partial): Spanish and French lesson resources are documented for multilingual learners; the full library's materials are not offered across a wide language range.
• Pivot Interactives (Not confirmed): The language coverage of Pivot's activities and materials was not established from public sources.
• Labster (Partial): Materials and simulations are offered in 5 listed languages (English, Italian, German, French, Spanish), varying by simulation.
• The Physics Classroom (Task Tracker) (Not confirmed): The language coverage of the tutorial and worksheet materials was not established from public sources.
• Inq-ITS (Partial): The whole product — labs, tutoring, and interface — is available in English and Spanish: genuinely localized, but only two languages.

Pricing

Free tier

What, if anything, is usable at no cost, on an ongoing basis (not just a trial)?

• OpenLab Science (Yes): Every lab, every preset, every printable sheet, and the built-in AI tutor are free, with no account and no paywall.
• PhET Interactive Simulations (Yes): The entire core simulation library is free, with no account required. PhET is funded by grants and donations — and is transitioning the collection from a CC BY to a non-commercial (CC BY-NC) license, with the exact scope and date unconfirmed.
• ExploreLearning Gizmos (Partial): A 30-day full-library trial is offered, after which a limited, rotating free selection remains — not an ongoing free tier at full breadth.
• Pivot Interactives (No): No meaningful ongoing free tier beyond a trial — this is a paid product from the outset.
• Labster (No): No meaningful ongoing free tier — the most expensive product compared here, aimed at institutional purchasing.
• The Physics Classroom (Task Tracker) (Partial): Concept Checkers and tutorials are free to browse; the Task Tracker assignment/grading layer requires a paid subscription.
• Inq-ITS (Partial): A 30-day trial and an informal free-teacher pilot path are offered; not an ongoing free public tier.

Paid tier / entry price

What does a school or teacher actually pay to get the full product, and how is it priced?

• OpenLab Science (No): None. There is no paid tier: the whole product, including the teacher tools, is free for students, teachers, and whole schools.
• PhET Interactive Simulations (Partial): PhET Studio, launched in 2025, sells saved-and-shared launch-state presets: $50 per editor per year (introductory; the $100 list price is struck through on the page), curriculum deployments from $5,000 per year, and custom commercial pricing — purchasable in the United States only. Studio collects no student work. The core library stays free either way.
• ExploreLearning Gizmos (Not confirmed): No public dollar price is published; pricing runs through a quote-based sales path. A public school-district procurement document (2025–26) lists a $2,995 site license (K-5); district-wide rollouts cost more.
• Pivot Interactives (Yes): Clear public per-seat pricing: $6.10/student/year for the grades 6–12 Classroom plan, $11.10/seat/semester for higher-ed options, with custom district quotes available.
• Labster (Yes): No public per-seat price is published: Labster quotes custom contracts, and its pricing FAQ states annual engagements typically begin at $5,000 USD.
• The Physics Classroom (Task Tracker) (Yes): Human-confirmed 2026-07-28: Standard (ad-free) tier $5/student/year under 75 students, $4/student/year at 75+. Ad-supported tier $2.50/student/year under 75, $2/student/year at 75+ (no student personal data shared with advertisers, though advertiser tracking cookies are used). Homeschool plan $50/child/year, ad-free, with a bundled Physics curriculum. $50 minimum order on every tier.
• Inq-ITS (Not confirmed): No public dollar price was found; pricing is tiered by student count through a district or multi-year quote.
