Seasons of the year

This chapter provides basic theoretical knowledge on the topic of „Seasons“, which is, from the perspective of the phenology-based approach to the curriculum of nature, indispensable. The sequencing of the seasons is adapted to the beginning of the school year; the time sequence in nature is not intentionally applied. Astronomers follow the Sun to determine the seasons of the year. Meteorologists determine the seasons according to changes in the weather. From the meteorological point of view, autumn starts on the first of September. The difference in the date of commencement of autumn from the two points of view, the one astrologers and the other of meteorologists, is due to the fact that changes in the temperature of the Earth’s surface are delayed behind the position of the Sun because a certain time is required to warm up or to cool the Earth’s surface. The seasons of the year alternate because the Earth’s axis is tilted and the angle of incidence of the Sun’s rays at which they hit the Earth changes.
