Learning material
From the foundations of primary school to deeper analysis
Each completed lake page explains the formation and shape of a lake, inflows and outflows, shoreline, water layers, bathymetry, area, volume, depth distribution, habitats, protected areas, species and the influence of people. Visual tables and maps help teachers connect natural science, geography, mathematics, environmental education and digital skills.
The materials first create a clear conceptual foundation and then lead smoothly to interpreting scientific parameters, comparing water layers and understanding why repeated measurements are needed.
