Abstract

The article is about the development of the personal competition of the first grade pupils during a science lesson theme “Electricity is very important and it is a very good assistant in a man’s life”. The students were asked to confirm or to deny sentence. Children accomplished two different tests. They follow safety requirements: they checked if the cord was unbroken, and they poked a power plug into a socket. On the basis of the practical work there was an educational film created (https://youtu.be/1kg7zrMYcU4). This film was shown to the classmates. Having learned from this film, other class students could accomplish the same tests. All the children liked it very much. The goal of the test: • To prove in practice that electricity is very important and it is a good assistant in the man’s life. The raised hypothesis: • Electrical items can do the same task better than a man, and to work with the electric items is much easier than with the manual devices. Necessary devices for tests: • For the first test we need: two eggs, two bowls, a whisk/manual eggbeater, an electric eggbeater, and a stopwatch. • For the second test we need: beans of coffee, a manual coffee grinder, an electric coffee grinder, a stopwatch and two plates. Results of the tests: • It is obvious, that the egg, which was whipped with the electric eggbeater was fluffy and the hand was not tired. • The coffee beans were grinded finer with the electric grinder. And other coffee beans which were grinded in a manual way were not so small. After the grinding the hand hurt. Conclusions of the tests: • The raised hypothesis was confirmed. The electrical devices accomplished the same tasks better than a man. To work with the electric devices is easier than with the manual ones. Advices for those who want to accomplish the same tests: • You can accomplish a test with the vacuum cleaner and the broom: “Dust cleaning”, or with the manual grinder and the electric grinder: “Who will crush the grains of buckwheat faster?” Keywords: engaging in educational material, educational method, practical work, smartphones.
