Binat Atid attended the University of Jews. This time they had to meet the Givat Ram campus, where they were studying the exact sciences. It was a long and saturated day, like all the days of the study tour of young intellectuals. The main challenge facing the programme is to familiarize itself with the academic system of education in Israel. The visit to the Givat Ram campus was the first stop on this route. Early this morning, at the campus gate, the boys met a student at the university, Dr. Boris Larin, who gave them an interesting lecture about…

On 17 September 1857, Constantine Tziolkovsky was born in the village of the Ijev Ryazan turbine family. In a 10-year-old age, Kostya got scarlatina and lost hearing. The boy was unable to attend school and had to study on his own.

Chemical experience with powder: how the powder explodes! The powder is smoke, or black, powder is a mixture of potassium selitre (calignite - KNO3), sulphur (S) and coal (C). It s flammable at about 300 °C. The powder could be blown up. It consists of oxidant (seliter) and reinstater (coal). The serial is also a reinstater, but its primary function is to connect the calium into a solid compound. When the powder burns, there is a reaction: 2KNO3+C+S circle K2S+N2+3CO2, which gives a large volume of gaseous substances

Today, in the output: simple electric motor on the battery; air balloon and -170°C; black sugar; free fall; dissolved shells; fuel for hydrogen machines. Attention: Some experiences can be hazardous to health. They need to be followed by security equipment. Below, look at six videos with explanations. Why is the wire spinning because there s an electrical charge in the wire? And that s nothing but an orderly motion of charged particles. Each of them has a magnetic field that deviates their direction. This rejection is called Lorenza s power. The…

The chlorine limb is used as a disinfectant and as a strong oxidant. 0, 5 g chlorine, cross the porcelain cup with several drops of salt acid. Gaseous chlorine is produced and determined by smell. Interesting studies can be carried out with a chlorine limestone on colour discoloration. To this end, prepare the meds in the water and let her stand. The visual layer It s common knowledge that the iodine solutions, when adding the solution to the edge, take the blue colour. Prepare a diluted aqueous solution of iodine (possible to use Lugol solution)…
