Explore Science ThroughInteractive Simulations
Discover Physics, Chemistry, and Biology through hands-on interactive simulations — enhanced with AI explanations, guided walkthroughs, and real-time learning support.
Explore by Subject
Choose a subject area to dive into curated simulations with AI-powered learning support.
Physics
Explore forces, motion, energy, waves, electricity, and the fundamental laws governing our universe.
Chemistry
Investigate atoms, molecules, reactions, states of matter, and the building blocks of all substances.
Biology
Discover life processes, genetics, evolution, cell biology, and the mechanisms of living organisms.
Build an Atom
Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas!
Circuit Construction Kit: DC
An electronics kit in your computer! Build circuits with resistors, light bulbs, batteries, and switches. Take measurements with the realistic ammeter and voltmeter. View the circuit as a schematic diagram.
Energy Skate Park: Basics
Learn about conservation of energy with a skater dude! Explore different tracks and view the kinetic energy, potential energy and friction as he moves. Build your own tracks, ramps and jumps for the skater.
Forces and Motion: Basics
Explore the forces at work when pulling against a cart, and pushing a refrigerator, crate, or person. Create an applied force and see how it makes objects move. Change friction and see how it affects the motion of objects.
Gene Expression Essentials
Explore how genes are expressed to make proteins. Observe transcription (DNA to mRNA) and translation (mRNA to protein). See how transcription factors regulate gene expression.
Gravity and Orbits
Move the sun, earth, moon and space station to see how it affects their gravitational forces and orbital paths. Visualize the sizes and distances between different heavenly bodies.
Molecules and Light
Do you ever wonder how a greenhouse gas traps heat from the sun? Explore how light interacts with molecules in our atmosphere. Start with the basics and then see how light interacts with ozone, oxygen, and other atmospheric molecules.
Natural Selection
Watch the bunnies multiply, adapt, and evolve! Add wolves and see how the population changes. Introduce mutations and see which traits are selected for or against.
Neuron
Stimulate a neuron and see how it fires an action potential. Explore how the action potential travels along the axon. Learn about the role of ion channels in nerve signaling.
pH Scale
Test the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Visualize the relative number of hydroxide ions and hydronium ions in solution.
Projectile Motion
Blast a Buick out of a cannon! Learn about projectile motion by firing various objects. Set the angle, initial speed, and mass. Add air resistance. Make a game out of this simulation by trying to hit a target.
States of Matter
Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time.
Wave on a String
Explore the wonderful world of waves! Wiggle the end of the string and make waves, or adjust the frequency and amplitude of an oscillator. Observe a string vibrate in slow motion.
