Chemisode Simulations
Interactive models and virtual practicals that help students connect chemistry and physics ideas with visible behaviour, laboratory equipment, modelled data and student-collected results.
Choose a simulation
Open any activity below. Each simulation includes its own instructions, controls and science explanation.
Simple Distillation
Build a liquid mixture, heat it and watch evaporation, condensation and collection in a working distillation apparatus.
Fractional Distillation
Explore how hydrocarbons separate through a temperature gradient according to chain length and boiling point.
Particles, Temperature & Density
Change temperature and compare particle motion, state changes and density across different substances.
Specific Heat Capacity
Run a vegetable oil practical, record results, plot and extrapolate a graph, calculate values and export a student logbook.
Water Solubility
Compare ionic, polar and non-polar substances and visualise how water molecules interact with each solute.
Precipitation Reactions
Choose two ionic solutions, predict the outcome, compare macroscopic and particle views, then write molecular and net ionic equations.
Gravimetric Analysis Laboratory
Perform interactive gravimetric investigations for sulfur in fertiliser, salt in chips and lead in soil using macroscopic and particle views.
Endpoint Rush
Control a burette, swirl the flask and judge indicator endpoints in practice, timed rush and quantitative analysis modes.
Spectra Lab
Explore how mass spectrometry, IR and NMR instruments produce spectra, then interpret evidence across 20 unknown organic compounds.
HPLC Chromatography Laboratory
Develop HPLC methods, run standards and samples, interpret retention times and use peak areas for quantitative analysis.
Potassium Nitrate Solubility Lab
Prepare test tubes, heat and cool potassium nitrate solutions, record crystallisation temperatures and construct a solubility curve.
Atom Builder
Build atoms and ions with protons, neutrons and electrons, then compare shell arrangements with advanced orbital diagrams.
Electromagnet Simulations
Explore four interactive devices showing how electric current creates magnetic fields and produces controlled movement.
Magnetic Field Lines Simulator
Add and rotate magnets, move a compass and explore field direction, strength, attraction and repulsion.
Invisible Wall
Connect potassium iodide and lead(II) nitrate with water, then observe where a yellow lead iodide boundary forms as the ions diffuse.
