Age levels

11–13 y.o.

The task set is designed for participants of a younger age with a basic level of knowledge. 8 tasks in the set include questions on classical astronomy and general concepts of the universe.

13–14 y.o.

The set of tasks is designed for participants continuing their exploration of the universe and the laws that govern it. 6 tasks are focused on classical questions in astronomy and the application of physical principles in space.

15–17 y.o.

This set of tasks is designed for participants with a solid understanding of fundamental astronomical concepts and laws.
The 10 problems in the set cover topics in astrometry, celestial mechanics, stellar astronomy, and the practical foundations of astronomy.

13–14 y.o.

To successfully solve the tasks, you need to know the names and symbols of chemical elements, the names and formulas of common inorganic compounds, be able to use the Periodic Table, understand molecular models, know the basic chemical properties of the main classes of inorganic compounds, be able to find stoichiometric coefficients in the reaction equations, know how to describe the composition of solutions, and be able to find the formula of an unknown substance based on quantitative data.

15–16 y.o.

Solving the problems in this set requires knowledge of the structure, physical and chemical properties of inorganic substances, as well as general principles governing chemical processes. The participants are expeted to perform calculations based on reaction equations, determine the composition of an unknown substance using quantitative data, and calculate thermochemical characteristics of processes based on qualitative reactions.
