Учителям 1-11 классов и воспитателям дошкольных ОУ вместе с ребятами рекомендуем принять участие в международном конкурсе «Законы экологии», приуроченном к году экологии. Участники конкурса проверят свои знания правил поведения на природе, узнают интересные факты о животных и растениях, занесённых в Красную книгу России. Все ученики будут награждены красочными наградными материалами, а учителя получат бесплатные свидетельства о подготовке участников и призёров международного конкурса.

AK-47 Lieutenant-General^ Mikhail Timofeyevich Kalashnikov (Russian: Михаи́л Тимофе́евич Кала́шников; 10 November 1919 – 23 December 2013) was a Russian general, inventor, military engineer, writer and small arms designer. He is most famous for developing the AK-47 assault rifle and its improvements, AKM and AK-74, as well as the PK machine gun. Kalashnikov was, according to himself, a self-taught tinkerer who combined innate mechanical skills with the study of weaponry to design arms that achieved battlefield ubiquity. Even though Kalashnikov felt sorrow at the weapons' uncontrolled distribution, he took pride in his inventions and in their reputation for reliability, emphasizing that his rifle is "a weapon of defense" and "not a weapon for offense".
Diesel engine Rudolf Christian Karl Diesel (18 March 1858 – 29 September 1913) was a German inventor and mechanical engineer, famous for the invention of the diesel engine and his mysterious death. Diesel was the subject of the 1942 film Diesel. The diesel engine (also known as a compression-ignition or CI engine) is an internal combustion engine in which ignition of the fuel that has been injected into the combustion chamber is initiated by the high temperature which a gas achieves when greatly compressed (adiabatic compression). This contrasts with spark-ignition engines such as a petrol engine (gasoline engine) or gas engine (using a gaseous fuel as opposed to petrol), which use a spark plug to ignite an air-fuel mixture.
Rubik's Cube Ernő Rubik (Hungarian: [ˈrubik ˈɛrnøː]; born 13 July 1944) is a Hungarian inventor, architect and professor of architecture. He is best known for the invention of mechanical puzzles including Rubik's Cube (1974), Rubik's Magic, Rubik's Magic: Master Edition, and Rubik's Snake. Rubik's Cube is a 3-D combination puzzle invented in 1974 by Hungarian sculptor and professor of architecture Ernő Rubik. Originally called the Magic Cube, the puzzle was licensed by Rubik to be sold by Ideal Toy Corp.
Maxim Gun Sir Hiram Stevens Maxim (5 February 1840 – 24 November 1916) was an American-born, British inventor who moved from the United States to the United Kingdom at the age of 41. He remained an American citizen until he became a naturalised British subject in 1900. He was the inventor of the Maxim Gun – the first portable, fully automatic machine gun – and held patents on mechanical devices such as a mousetrap, hair-curling irons, and steam pumps. He laid claim to inventing the lightbulb, and even experimented with powered flight, but his large aircraft designs were never successful. However, his "Captive Flying Machine" amusement ride, designed as a means by which to fund his research while generating public interest in flight, was highly successful. The Maxim gun was invented by Sir Hiram Stevens Maxim in 1884, and was the first recoil-operated machine gun. It has been called "the weapon most associated with British imperial conquest".
