20 October is International Arbor Day. Also on this occasion, in biology class with the fifth graders, we tried to show the others how magical and important the forest is on Earth and that it really looks like a prefabricated house. We created a 3 D model of the forest layers. Each floor has its role in the forest and a huge importance for the cycle of life. In addition, our squirrel in the schoolyard made our work more pleasant.
