Chemistry Simulations
Free interactive chemistry simulations for all grades. Explore teacher-made K-12 chemistry simulations — projector-ready, and built for the classroom.
Free interactive states of matter simulation. Explore states of matter hands-on online — great for whole-class or independent practice.
Free interactive phases of matter simulation. Explore phases of matter hands-on online — great for whole-class or independent practice.
Mix hydrogen and oxygen and make water. Count atoms before and after, get the ratio wrong and watch one reactant run out first, then heat the flask and see the reaction speed up.
Free interactive evaporation and condensation simulation. Explore evaporation and condensation hands-on online — great for whole-c

Explore the quantum picture of hydrogen: rotate electron probability clouds, compare four orbitals, reveal nodes in a central slice, and build a cloud from independent position measurements.
