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.
