As part of the library laboratory “Funny Science” on April 16th, a master class “Seething Lava” was held. An example of a volcanic lava eruption was presented to the children. This same phenomenon that occurs during a chemical reaction was invented in 1754 by Joseph Black (Scottish physicist and chemist).
In our library laboratory, the guys learned about various types of volcanoes and other interesting facts. The experiment was simple and safe, aimed at developing in children such skills as observation, comparison, analysis, generalization. The most interesting thing is that the necessary substances for the experiment are available to everyone that is used in everyday life: soda (sodium bicarbonate), citric acid, vegetable oil, red dye. It is with the help of these additives that our interesting experience can be repeated at home. Only with the help of adults!
As a result of the master class, a review of thematic books and magazines on fascinating chemistry was carried out.
