The document outlines activities carried out by students from the 7th B class at Escola Secundária C/ 3o CEB do Fundão to map the forest ecosystems in Portugal. The activities included visiting a local forest to collect materials like mushrooms, plants, leaves, seeds and soil. In the classroom, students conducted experiments with the collected soil, classified leaves and plants, sowed seeds of Quercus pirenaica, and made Christmas postcards about the forest. Other classes contributed activities related to measuring the forest area, studying the landscape and weather. Photos from forest visits and an herbarium site are also mentioned.
