Interactive Simulations
Interactive simulations built for the revised Class IX syllabus. Explore, experiment, and understand — right in your browser. 4 simulations are free. Unlock all with Early Access.
Launch any simulation below instantly. No account needed. Each links directly to the full interactive experience.
Spin an interactive 3D globe, explore tectonic plate boundaries, hotspots, and continental drift.
Watch the animated story of the Indian–Eurasian plate collision forming the world's mightiest mountain range.
Control a car through uniform and accelerating motion and watch Distance-Time and Velocity-Time graphs plot live.
Build atoms interactively — add protons, neutrons, and electrons. Explore Bohr's model and electron shells.
Geography, History, Political Science, and Economics — brought to life through interactive exploration. Covers the complete Class IX Social Science syllabus under NCF-SE 2023.
Spin an interactive 3D globe, explore tectonic plate boundaries, hotspots, and trace how continents have drifted over millions of years.
Watch the animated story of how the Indian plate collided with the Eurasian plate over 50 million years to form the world's mightiest mountain range.
Simulate seismic waves spreading from an epicentre, watch a tsunami form in the open ocean, and understand why coastal regions are most at risk.
Follow the South-West monsoon as it sweeps across India month by month — see how pressure gradients, land masses, and the Western Ghats shape rainfall patterns.
Ascend through the troposphere, stratosphere, mesosphere, and beyond. Discover what happens to temperature, pressure, and air composition at each layer.
Navigate a clickable world map to explore tropical rainforests, grasslands, deserts, and tundra. Compare climate, vegetation, and wildlife across biomes.
Make lifestyle and policy choices and watch their impact on atmospheric CO₂ in real time. Understand deforestation, industry, and transport as key drivers.
Visualise warm and cold ocean currents on an interactive globe. Explore how they regulate climate, influence rainfall, and affect coastal fisheries.
Observe how the Moon's gravitational pull creates high and low tides. Simulate wave formation, coastal erosion, and the difference between tides and tsunamis.
Apply physical, chemical, and biological weathering agents to different rock types and watch landscapes transform over geological time.
Journey from Australopithecus to Homo sapiens on an interactive timeline. Compare skull shapes, brain sizes, and tool use across 3 million years of evolution.
Transition a nomadic group into a settled farming community. Manage crop selection, tool development, and the rise of the first permanent settlements.
Compare Mesopotamia, Egypt, Indus Valley, and China — their rivers, urban planning, writing systems, and governance structures side by side.
Navigate the Silk Road, Indian Ocean trade networks, and the Spice Route on an animated map. See how goods, ideas, and religions moved across the ancient world.
Map the rise and fall of medieval empires across Asia and Europe. Examine feudalism, military campaigns, religious institutions, and the spread of knowledge.
Compare democratic systems across countries. See how constitutional rights, separation of powers, and civil liberties vary — and what makes democracy work.
Run an Indian general election from campaign to counting. Understand first-past-the-post voting, voter turnout, the role of the ECI, and coalition formation.
Compare proportional representation, FPTP, and mixed electoral systems with the same set of votes applied to each. See how different systems produce different outcomes.
Shift demand and supply curves and watch the equilibrium price and quantity adjust in real time. Understand price signals through a live market simulation.
Make resource allocation decisions under scarcity. Visualise trade-offs on a Production Possibility Curve and understand why every choice has a hidden cost.
Set government price controls and observe their unintended effects — shortages, surpluses, black markets — in a live market with adjustable sliders.
Compare simple and compound interest over time with interactive charts. See how banks, loans, and savings work, and why compounding is called the "eighth wonder".
Launch a small business and navigate real economic decisions — pricing, costs, revenue, profit, and break-even point — in a guided startup simulation.
Physics, Chemistry, Biology, and Earth Science — interactive labs that replace passive reading with hands-on exploration. Built for the Class IX Science syllabus under NCF-SE 2023.
Drive a car through uniform, accelerating, and decelerating motion. Watch live Distance-Time and Velocity-Time graphs plot in real time as you control speed.
Draw your own motion graph and watch the simulation play it back. Reverse-engineer what a graph means before calculating it — understand before memorising.
Apply forces to objects and observe inertia, acceleration, and action-reaction pairs. Interactive scenarios illustrate all three of Newton's laws with adjustable parameters.
Slide objects across surfaces with different textures and masses. Measure static and kinetic friction, and see how lubricants and normal force change the outcome.
Roll a ball down a ramp and track the conversion between kinetic and potential energy at every point. See the law of conservation of energy in animated form.
Operate levers, pulleys, inclined planes, and wheels. Adjust load and effort to see how each machine provides mechanical advantage and changes the direction of force.
Swing an object in a circle and explore centripetal force, angular velocity, and period. Change the radius and mass to see how they affect the force needed.
Visualise longitudinal sound waves, adjust frequency and amplitude, and see how compressions and rarefactions travel through different media.
Fire a sound pulse at surfaces and measure the reflected echo. Calculate distances using the speed of sound — just like sonar, ultrasound, and bat navigation.
Build atoms interactively — add protons, neutrons, and electrons. Explore Bohr's model, electron shells, and the relationship between atomic number and mass number.
Fill electron shells step by step following Aufbau's principle. Predict the chemical properties of elements based on their outermost shell configuration.
Apply filtration, evaporation, distillation, and chromatography to separate mixtures. Choose the right technique based on the properties of each substance.
Drag and drop ions to form ionic and covalent compounds. The simulation validates valency rules and displays the correct chemical formula instantly.
Run chemical reactions in a virtual sealed container and verify that total mass before and after is always equal. Build intuition for balancing chemical equations.
Dissolve salts in water at different temperatures and plot the solubility curve. Predict when crystallisation occurs and understand saturated vs unsaturated solutions.
Zoom into plant and animal cells and identify every organelle. Compare prokaryotic and eukaryotic cells, and understand the function of each component.
Examine microscope slides of epithelial, connective, muscle, and nervous tissue. Identify structural features and match each tissue to its body function.
Sort organisms across Monera, Protista, Fungi, Plantae, and Animalia. Explore classification criteria, evolutionary relationships, and key examples from each kingdom.
Place cells in hypotonic, isotonic, and hypertonic solutions and observe water movement across the semi-permeable membrane. See turgidity and plasmolysis happen live.
Guide pollen from stamen to pistil through wind, water, insects, and birds. Explore self-pollination vs cross-pollination and trace the journey to fertilisation.
Step through cell division phase by phase — prophase, metaphase, anaphase, telophase. Compare mitosis and meiosis side by side and understand why each matters.
Trace the movement of carbon, nitrogen, and water through the atmosphere, biosphere, and lithosphere. See how human activity disrupts these natural cycles.
Heat land and water surfaces with simulated sunlight and measure how they warm and cool at different rates. Understand why land heats faster and sea breezes form.
Observe how pressure gradients and the Coriolis effect combine to create trade winds, westerlies, and polar easterlies. Link global wind patterns to India's climate.
