📖 Features — Detailed Guide

1 · 125+ Working Canvas Simulations

Each subject (Physics, Chemistry, Biology, Mathematics, General Science) now ships 25 interactive simulations rendered on the HTML5 Canvas with realistic SVG laboratory apparatus. They run entirely in your browser — no plugins, no servers.

How to use: open a subject hub → click any simulation card → adjust the sliders and observe in real time. Most labs include a built-in Record button to capture data, plus an auto-graded quiz at the bottom.

• Physics (25): 10 originals (pendulum, projectile, waves, Ohm's, lens, Hooke's, gas laws, SHM, induction, photoelectric) + 15 new (free fall, Newton's 2nd Law, friction, energy, momentum, density, pressure, refraction, sound, specific heat, capacitor, Doppler, radioactivity, thermal radiation, spectrum).
• Chemistry (25): 10 originals + 15 new (atomic structure, molar mass, solubility, concentration, equilibrium, kinetic theory, Hess's Law, buffers, catalysis, polymers, indicators, empirical formula, periodic trends, thermo, crystallisation).
• Biology (25): 10 originals + 15 new (plant cell, enzymes, respiration, heart beat, kidney, digestion, mitosis, food chain, blood types, breathing, skeleton, muscle, ecosystem, Punnett square, Darwin's finches).
• Mathematics (25): 10 originals + 15 new (linear, factoring, derivatives, integrals, limits, logs, exponentials, circle geometry, permutations, complex numbers, number bases, central tendency, percentage, compound interest, plus repeat coverage).
• General Science (25): 10 originals + 15 new (weather, water cycle, food pyramid, climate change, renewables, recycling, seasons, tides, acid rain, music, magnetic field, star life cycle, plate tectonics, biodiversity, plus more).

2 · 🔬 Interactive Equipment Gallery (NEW in v7)

The Equipment Gallery (under Tools → Equipment) contains 36 realistic SVG laboratory apparatus drawn in vector graphics for crisp display on any screen:

Beaker · Conical Flask · Test Tube · Bunsen Burner · Compound Microscope · Thermometer · Digital Balance · Voltmeter · Ammeter · Dry Cell · Lamp · Switch · Resistor · Burette · Bar Magnet · Compass · Simple Pendulum · Tripod Stand · Petri Dish · Refracting Telescope · Pipette · Filter Funnel · Potted Plant · Spring · Trolley · Inclined Plane · Pulley · Convex Lens · Concave Mirror · Stopwatch · Bohr Atom · DNA Helix · Heart · Brain · Volcano · Ringed Planet.

How it works: search by name, filter by subject (Physics/Chemistry/Biology/Gen Sci), click any card to open a full-size modal with description and common uses. Apparatus also appears on every simulation page on a wooden virtual lab bench, so students always know what real-world tools they are simulating.

3 · Interactive Periodic Table (118 elements, fixed in v6)

All 118 elements correctly placed with search by name/symbol/atomic number, category filter, electron configuration, electronegativity, state at STP, group, period and common uses.

4 · Built-in Quizzes & Auto-Grading

Every simulation page ships with a 3-question multiple-choice quiz. They are scored instantly with feedback. Teachers can also build their own quizzes in the Assessment Builder.

5 · Teacher Dashboard · Classroom · Assessments · Reports

Manage classes (with shareable codes), students, assessments. CSV bulk import onboards an entire class in seconds. Reports include CSS-rendered bar charts and CSV export. Backup & restore exports a single JSON file containing all your data.

6 · Student Portal

Students create a profile, see level & points, view all 10 unlockable badges (locked ones dimmed), check progress per simulation and watch live leaderboard.

7 · Parent Portal

Parents search by student name or ID — view points, level, completed sims and badges. All data stays in browser localStorage.

8 · School Admin Dashboard

Enterprise-grade overview: total classes, students, sims completed, badges, quizzes, average scores. Includes school branding, activity log and full data backup/restore — all free.

9 · Gamification

10 unlockable badges, points system (10 per sim, 50 per badge), levels (200 pts each) and real-time top-20 leaderboard.

10 · Tools Suite (7)

• Equipment Gallery (new) — 36 SVG apparatus.
• Interactive Periodic Table — 118 elements.
• Scientific Calculator — sin, cos, tan, log, sqrt, powers, memory.
• Graphing Tool — plot up to 3 functions.
• Stopwatch / Lap timer — millisecond precision, CSV export.
• Unit Converter — 8 categories.
• Equation Solver — linear, quadratic, 2×2 simultaneous.

11 · Community Forum & OER Library

A simple browser-local forum and a seeded library of free external resources (PhET, Khan Academy, WAEC syllabi, Desmos, NASA, etc.).

12 · Dark Mode + PWA (Install on Phone)

Toggle dark mode from the top bar. The app installs as a Progressive Web App on Android/iOS — works offline on 2G or no network.

13 · 100% Free, Privacy-First

No AI APIs, no analytics tracking, no backend, no login servers. All data stays in localStorage. Deploy on any free static host (Cloudflare Pages, GitHub Pages, Vercel, Netlify) at zero cost.
