Science step by step
Ten guided routes from an accessible question to deeper chemistry and physics.
Periodiskās tabulas karte
Read the periodic table as a map: position, electrons and recurring chemical behaviour.
No atomiem līdz saitēm
Follow the path from atomic structure to the forces that hold molecules and solids together.
No moliem līdz reakcijām
Connect particles, amount of substance, balanced equations and measurable laboratory quantities.
Enerģija ķīmijā
See how bond changes, heat, enthalpy, entropy and Gibbs energy fit into one story.
Gaisma un atomi
Connect photons, spectra, energy levels and the fingerprints that reveal chemical elements.
Izotopi un laiks
Understand isotopes, radioactive decay, half-life and why nuclear clocks can measure time.
Gāzes, spiediens un temperatūra
Build intuition for pressure, volume, temperature and the ideal-gas model.
Skābes, bāzes un līdzsvars
Move from proton transfer to pH, equilibrium and the meaning of a chemical buffer.
Elektrība un viela
Connect charge, electrons, ions, electric fields and the movement of current.
Viļņi un mērīšana
Use wavelength, frequency and amplitude to understand sound, light and scientific measurements.
