He jumped from the street, took off his shoes, stroked the cat anddarted to the table. All children do that, what could be there. Even the most refined and obsessed with clean moms. The child simply does not understand why you need to wash your hands - they look clean enough, the dirt has not even begun to fall off. And what will happen if you touch a perfectly clean cat? Never mind! It is in this insane struggle that mothers earn a neurosis for themselves, forcing the child to wash their hands, and then checking if he has washed them. Even if the child is already 40 years old.A photo: GettyImages A teacher from North Carolina, USA, has found a way to solve this problem. Does the child believe only what he sees? So, you need to show him microbes clearly. "My colleagues said that this is the most disgusting, but also the coolest experiment," says Donna Gill, author of the technique. All that is needed for the experiment is three pieces of bread. One of them will be a control copy - you need to take it with tweezers and put it in a clean plastic bag. Take the second piece with just washed clean hands and also send it to the package - this is a clean piece. “The third piece should be given to each student in the classroom. And only after that, put in a bag labeled “dirty,” Donna explains. After a few days, the children will see the practical results of the experiment. The bread that each student touched simply stabbed with mold. Control and clean the same pieces remained the same as they were.Photo: @donna.g.allen.5"This is a great way to explain to children why it is so important to wash their hands," the teacher is sure. By the way, Donna is not the first to teach children hygiene in such a visual way. A similar experiment was described in the textbook "The Human Body", published in the 70s of the last century. Only there, Petri dishes were needed for it: the child touches one with dirty hands, another - with not very thoroughly washed hands, the third - with thoroughly washed hot water and soap. And then he watches how differently intense the vegetation grows in each of the dishes. The authors of the book assure that after this, the boy not only did not forget to wash his hands, but did it fanatically.
