How to make model of the Solar system ? Our Solar System About 4,6 milliard years ago, the Sun and the planets were formed from a cloud composed of dust and gases. 99,9% of the total mass of the Solar System is concentrated in the enormous Sun. Around the Sun, attracted by its powerful gravitation, nine planets rotate with their more than 100 satellites and a great number of smaller cosmic bodies – small planets/asteroids, comets and meteor bodies (meteoroids). The planets are divided into two main groups: internal, planets of the terrestrial group – Mercury, Venus, Earth and Mars and external – giant planets – Jupiter, Saturn, Uranus and Neptune. Pluto belongs to the category of dwarf planets. The planets rotate around the Sun in the direction from west to east. Their orbits are almost circular, and their planes almost conside with the equatorial plane of the Sun. The proposed model of the Solar System can be made in the classroom, as well as at home in the form of a given homework. It visualizes the educative process in “Man and Nature” at a primary and junior high-shool stage, but can be used by the teacher also for teaching the subject of “Physics and Astronomy”. The arrangement of the planets is according to the principle of their formal division into internal (close to the Sun) and external ones. The dimensions of the Sun and the planets approximately correspond to the real ones on the respective scale.

Necessary materials: Balls made of styrofoam of different diameters, a cone made of styrofoam, small wooden spits, a tray made of styrofoam (from sweeties or biscuits), glue – silicone, acryl paints. Mode of work: You cut 8 small spits of different length and fix each of the planets to the Sun (the largest ball) on one plane. You fix the Sun with a small spit to the cone, which you sticked to the tray in advance (for a geater support). The pupils can colour the Sun and the planets (in advance or after that) with acryl paints, observing photos from textbooks, encyclopedias or from Internet sites in astronomy.
