In the course "How Plants Work", children discover what plants need to grow and how they absorb, transport, and store energy. They learn about the key growth factors and investigate how plants transport water. In simple experiments, they explore how plants store energy in the form of starch, how heat can be produced in the process, and why leaves are green. Fundamental processes of photosynthesis are introduced – such as light absorption by chlorophyll, the function of chloroplasts, and oxygen production. By examining leaves and plant structures under the microscope, children gain fascinating insights into the internal structure of plants, prepare their own slides, and independently observe stomata or leaf cross-sections.
