    November was the month when our students performed air activities. Here is what the students did in nature, geography, art, chemistry, physics, mathematics and biology lessons. In the nature lessons, fourth grade students observed the "production" of oxygen by Canadian urea in the process of photosynthesis, and based on experience, they concluded how hot and cold air behaves. Class 4b students showed great ingenuity by building remarkable anemometers. In the geography lesson, the students learned about the influence of air masses on the climate of Poland. During the art and technology classes, the students performed works inspired by the air movement - the mobile type. The 5 classes were made by fantastic creatures with a structure moving on the air. Autumn breezes and gale were also the subject of works with wind-powered umbrellas or rocking, slowly falling leaves made in graphic techniques (frotage or prints from paint). In the fifth grade there was a biology lesson devoted to the role of air components such as carbon dioxide and water vapor (water) in the process of photosynthesis. The students also observed experience confirming that one of the photosynthetic products is oxygen - the most important component of the air. On the other hand, in chemistry classes in the seventh grade, students learned the air as a homogeneous mixture of gases. They experimentally studied the approximate composition of air, determined its properties. They got to know some of the constant and variable air components (oxygen, carbon monoxide (IV), nitrogen, noble gases, hydrogen). Eighth grade students had to perform a lichen scale. It is a scale that, by observing types of thallus of lichens growing on the bark of deciduous trees, allows to assess the level of air pollution with sulfur (IV) oxide in a given area. Lichens serve as the indicator species (bioindicator) here. With the scales prepared by them, students went to a field lesson to determine the concentration of this pollution in the air around the school. Conclusions from the lesson: the concentration of sulfur dioxide in the air around the school varies within 100-170 μg SO2 / m3, and sometimes even above this value.
