Today, the children of the Polyanskaya School of the Spasskiy district tested the Pchelka-U/Khim express-laboratory and told about the results of their project. Let us recall, the mini express laboratory was given to the Polyanskaya School not by chance. The pupils became the winners of the republican contest "School Eco-patrol". Mini lab helps schoolchildren to perform a lot of tasks. Its uniqueness is that children can work independently, without participation and control of adults.
