Forces & Motion
Change mass, surface friction and applied force. Watch acceleration, net force and velocities respond in real time.
Thermo Forge
Read reaction energy profiles, calculate calorimetry heat transfers (q = mcΔT) and predict Gibbs free energy & spontaneity.
Equation Forge
Balance chemical equations with real-time atom inventories, drag-and-drop stoichiometric coefficients and custom reaction tests.
Ion Forge
Add or remove electrons, read the net ionic charge and forge stable octet ions against the clock.
States of Matter
Heat and cool different substances. Watch particle kinetic motion, spacing, pressure and phase changes respond.
DNA Replication
Open the double helix, apply helicase, primase, DNA polymerase and ligase to build leading and lagging strands.
Protein Synthesis
Transcribe DNA genes into complementary mRNA messages, then translate codons at the ribosome to build polypeptides.
Gene Expression
Regulate a gene promoter, transcribe mRNA and watch ribosomes translate it into functional proteins.
Calculus Grapher
Explore derivatives, tangent slopes, integrals and accumulated area under curves on one responsive graph.
