Science step by step
Ten guided routes from an accessible question to deeper chemistry and physics.
Mapa de la taula periòdica
Read the periodic table as a map: position, electrons and recurring chemical behaviour.
Dels àtoms als enllaços
Follow the path from atomic structure to the forces that hold molecules and solids together.
Dels mols a les reaccions
Connect particles, amount of substance, balanced equations and measurable laboratory quantities.
Energia en química
See how bond changes, heat, enthalpy, entropy and Gibbs energy fit into one story.
Llum i àtoms
Connect photons, spectra, energy levels and the fingerprints that reveal chemical elements.
Isòtops i temps
Understand isotopes, radioactive decay, half-life and why nuclear clocks can measure time.
Gasos, pressió i temperatura
Build intuition for pressure, volume, temperature and the ideal-gas model.
Àcids, bases i equilibri
Move from proton transfer to pH, equilibrium and the meaning of a chemical buffer.
Electricitat i matèria
Connect charge, electrons, ions, electric fields and the movement of current.
Ones i mesura
Use wavelength, frequency and amplitude to understand sound, light and scientific measurements.
