Rola monitoringu procesów zachodzących…
Zachęcamy do wykorzystania danych z monitoringu przyrodniczego, zgromadzonych przez uczniów w projekcie EDUSCIENCE, a także uświadomienia uczniów jak dużą rolę monitoring środowiska odgrywa w badaniach naukowych i codziennym życiu.
Zapraszamy na lekcję online: Kiwi…
Lekcja będzie prowadzona z Polskiej Stacji Antarktycznej im. Henryka Arctowskiego.
Zachód słońca w Hornsundzie
W Polsce koniec sierpnia kojarzy się ze szkołą, kasztanami i grzybobraniem. Jednak w Polskiej Stacji Polarnej na Spitsbergenie to wspaniała okazja, żeby podziwiać pierwszy od blisko czterech miesięcy zachód słońca.

Zapomniane oblicze pokrzywy
Pokrzywa zwyczajna (Urtica dioica L.) to jedna z tych roślin, którą poznajemy już we wczesnym wieku i to najczęściej od tej nieprzyjemniej strony. Swędzenie, zaczerwienienie, wysypka to częste efekty spotkania z pokrzywą.
