Interactive Science Education
Master complex scientific concepts through hands-on, visual simulations designed for students, educators, and curious minds.
Every simulation opens with what you'll learn, so you know what to look for before you start.
Guided "Try this" steps walk you through the key experiments. Then change anything and see what happens.
Each page ends with a full explanation of the science and equations behind what you just saw.

Stimulate a labeled neuron and follow a real action potential from the cell body, down the myelinated axon, to the synapse. Powered by a full Hodgkin-Huxley model with live voltage and ion-channel plots.
Launch SimulationWatch helicase open the replication fork while DNA polymerase builds the leading strand in one piece and the lagging strand in Okazaki fragments. Step through it base by base.
Launch SimulationBuild s, p and d orbitals in 3D, then combine orbitals from two atoms into σ and π, bonding and antibonding molecular orbitals, with bond order worked out for you.
Launch SimulationExplore a model of the solar system whose orbits follow Kepler's laws, including the asteroid belt and Earth's Moon. Hover or click any planet to compare its distance, period and eccentricity.
Launch SimulationPlace two wave sources and see exactly where they add up and where they cancel. Change wavelength, amplitude and spacing to reshape the interference pattern in real time.
Launch SimulationDraw any wave or pick a preset, then watch rotating circles rebuild it one harmonic at a time, with its frequency spectrum and coefficients alongside.
Launch SimulationFour experiments in one: the double slit, wave functions in a box and on a spring, tunneling through a barrier, and the uncertainty principle.
Launch SimulationOur simulations provide hands-on experience with complex scientific concepts, making abstract ideas concrete and accessible.
All simulations are built on accurate scientific models and principles, ensuring that students learn correct information.
Designed with educators in mind, our simulations integrate seamlessly into lesson plans and can be used for demonstrations or student exploration.
Web-based simulations work on any device with a browser, making them perfect for classroom, home, or remote learning environments.
