When children begin to study the concept of solarsystems, realize the fact that all planets "swirl" around the Sun, for them this process can be difficult and overwhelming. However, the child can better understand these principles, if you make a visual aid. Of course, it will be better and more pleasant if the parents with their son or daughter make their own models of the solar system. Although many moms and dads do not consider it necessary and buy ready mock-ups.
Solar system: general information
The planet Earth makes one revolution every yeararound the center of the solar system - the Sun. All planets revolve around the "center" of the universe for a certain amount of time. For example, Mercury "bypasses" the Sun for 88 terrestrial days, and Uranus - for 84 terrestrial years. In total, there are 8 planets in our system: Mercury, followed by Venus, then Earth, followed by Mars, followed by Jupiter, then Saturn, followed by Uranus, then Neptune. Each of them, together with meteors, satellites, comets, dust or gas formations is an integral part of the solar system. The planets closest to the Sun are very hard because of the constant high temperature. As you move away from the star, the temperature gradually decreases.
Features of some planets
The smallest planet isMercury. This object of the galaxy is located closest to the Sun. Because of this, the atmosphere is completely burned out. And on the bright side, the temperature reaches + 430 °, and on the dark side - -170 °.
Of particular interest is Saturn with its rings. This planet has a three-layered atmosphere. The rings of Saturn consist of rocks and ice. On the surface of the planet, the temperature reaches -150 °.
To understand the principle of "working" of our "microgalaxy", one can make models of the solar system one of the ways. So you can decorate the interior and make an excellent visual aid.
Option number 1. How to perform the reconstruction of the solar system
To create a solar system you will need:
- cut from a cardboard circle (diameter about 30 cm);
- a simple pencil;
- colored paper;
- fishing line;
- colored pencils and markers;
Step 1. In the center of the cardboard circle, two perpendicular lines must be drawn. The intersection of these diameters will serve as a fixation point for the Sun.
Step 2. Using the compass, the parent or the kid should draw 8 circles of different diameters, which will serve as orbits. It should be taken into account that 4 orbits should be closer to the Sun. Then leave a gap for the asteroids. Then follow the "home" for the rest of the planets. After the outline of the orbits, you need to make a hole in the cardboard with scissors. One of the holes should be in the center. The rest are in chaotic order, one hole in each orbit.
Step 3. From color paper of the appropriate color, you need to cut out the planets and the Sun. On each cut circle you can write the names of the planets.
Step 4. With the help of Scotch tape, you need to attach the line to the objects. The free end of the line is adhered to the outside of a large cardboard circle by duct tape. The planets are in such a sequence, starting from the closest to the Sun: the first is Mercury, the second is Venus, the third is Earth, the fourth is Mars, the fifth is Jupiter, the sixth is Saturn, the seventh is Uranus, the eighth is Neptune.
Step 5. The length of the line can be adjusted to your liking. After fixing the planets, you need to hang a model of the solar system, made with your own hands, with the help of connected three pieces of the line of the same length with one longer segment with the ring. The model is ready.
Option number 2. How to perform the reconstruction of the solar system
To create a 3d model of the solar system, you need to prepare the following materials:
- a large ball of foam;
- 9 bamboo skewers;
- 9 balls of foam plastic;
- adhesive tape;
- scissors or knife;
- paint, pins, fishing line;
Step 1. Cut the strips of adhesive tape, sign them by the name of each of the planets and the sun.
Step 2. Prepare 9 bamboo skewers of different lengths:
- I - 2.5 inches = 6.35 cm;
- II - 4 inches = 10.16 cm;
- III - 5 inches = 12.7 cm;
- IV - 6 inches = 15.24 cm;
- V - 7 inches = 17.78 cm;
- VI - 8 inches = 20.32 cm;
- VII - 10 inches = 25.04 cm;
- VIII - 11.5 inches = 29.21 cm;
- IX - 14 inches = 25.56 cm.
Step 3. Draw the prepared foam balls with colors in accordance with the color of the planet: the Sun (the largest ball) - yellow, the Earth - green and blue, Mars - red, etc.. Wait until the paint dries completely.
Step 4. Stick the labeled pieces of adhesive tape onto the dried balls.
Step 5. 2.5 inch skewer to attach to the Sun, and on the other end to attach Mercury. Then the rest of the planets are fixed in the same way in the correct order.
Step 6. You can tie up the created system, attaching a pin and line to the model of the Solar system.
That's it. You can create various models of the solar system from numerous materials. The main thing is to give vent to fantasies and study literature.
Another similar model, made of papier-mache.
A few examples of the models of the solar system made with their own hands are shown in the photos below.
These images show that you do not need to be a sideman in order to make a visual, convenient and simply beautiful reconstruction of the solar system.</ p>
