My holidays in the planet Earth

When we travelled to planet Earth we saw that human have a very strange education. Children have to go every day to a place (school) where they learn about different kinds of subjects while their parents normally are working. In the school the children have to go to a place (class) where an adult person teaches them in the different subjects. In this place children normally can be girls or boys and don´t have the same skin but they usually have the same age and they have to wear a uniform or not depending of the school. In the class the children are sitting in front of the adult person and they are listening. Sometimes one child can raise the hand and says something about the subject or they can speak when the adult person asks them. Finally we observed that children have a little time between classes to have a rest, eat something, go to the bathroom or play with their friends and classmates.
