fieldwork and classroom work:
Students work in small groups to investigate selected trees in their local environment. They identify tree species and measure tree height using three different methods: the GLOBE Observer app, the pencil method and the mirror method. They also measure tree circumference at breast height and use the collected data to calculate tree diameter, estimate tree age, above-ground biomass, stored carbon and the amount of CO₂ absorbed by the tree.
The students compare the results obtained using different measurement methods, analyse possible sources of measurement error, create graphs showing the relationship between tree size, age and carbon storage, and discuss the role of trees in the carbon cycle. The activity concludes with the creation of a digital poster presenting their results and conclusions.
